vi 224/424 Operator’s Manual - 880027-1000
Introduction
This manual covers both the 224 and 424 printers. The primary difference in the two
printers is print width. The 224 uses a 2.1 inch (53mm) print head and the 424 uses a 4.1
inch (104mm) print head. Both printers are offered with a standard resolution of either 203
dpi (8 dots/mm) or an optional 300 dpi (12 dots/mm). The print mechanisms of the 224 and
the 424 printers utilize different parts to account for the difference in print width. Otherwise,
the printers are virtually identical. This manual will use the 424 for illustration purposes.

NULL modem cable is not necessary. A serial data cable is required to use serial
communications, refer to Table 3-1 below for correct cable configurations.
The factory settings, unless otherwise requested, are set at 115200 baud, 8 data bits, 1 stop
bit and no parity with both hardware and software handshaking enabled. The baud rate is
user selectable from 110 to 115,200 and uses software XON/XOFF flow control and/or
hardware CTS handshaking.
If XON/XOFF handshaking is used, the only signals that the printer requires are the RXD,
TXD, and GND signals. If the hardware handshaking is used, then the CTS and RTS signals
are required. The other signals are offered in the event that the host computer would
require them.
3.2.2.1 RS-232 Serial Cables
The printer uses a standard through serial cable, typically referred to as a modem cable,
which may be purchased through Microcom Corporation or a local computer supply
company. A NULL-modem cable is not required because the printer is configured as DCE.
For a 25-pin serial communication port – Use a 25-pin female to 9-pin male cable.
For a 9-pin serial communication port – Use a 9-pin female to 9-pin male cable.

3.2.3 USB Communication Interface
A standard USB 1.1 connector is provided on the rear panel of the printer. The USB port
operates as a virtual serial communications port and requires the installation of the
Microcom Corporation supplied USB driver for proper operation. The USB cable must be
connected to a host PC that is already powered on before the printer is turned on. The
^D108 command is used to select the USB port and requires a power cycle to take affect.
3.2.4 Optional Ethernet Communication Interface
The Model 224 and 424 printers provide an optional 10/100BASE-T Ethernet connector on
the rear panel of the printer. The ^D108 command is used to select the Ethernet port at
power-up.
3.2.5 Optional Cutter Interface
The printer is fitted with a connector on the rear panel for the optional cutter interface. Use
this connector when a cutter is to be installed on the printer. To prevent damage to the
printer and/or cutter, connect the cutter when the printer power is off. The cutter type is set
by the user using the ^D115 command and will be reported on the Statistics Label.
3.3 Loading Media
The easy- to-release print head makes loading media into the Model 224/424 printer an
easy process. Follow the instructions below to properly load the media.
1. Feed the media into the paper path, located on the back of the printer, until you feel
resistance.
2. Push and hold the Print Button to feed the media through the printer.
3. Once the media exits the front of the printer, release the Print Button.
The printer is also equipped with an Auto-Load feature. This feature allows the printer to
automatically sense new media as it is inserted into the printer, and automatically feed the
media to provide proper registration of the first label/tag to either the leading edge or a
registration mark. For more details on this feature, please refer to Chapter 5, Auto-Load
Commands.

3.5 Printer Modes
The printer has four primary modes of operation. The different types of modes have an
impact on how the Print Button and the Status Indicator Light operate. This section is
intended to provide the user with an explanation of these different modes.
3.5.1 Idle Mode: GREEN
The printer is in the IDLE Mode when it is not printing and/or has no pending activity. The
indicator light is GREEN, which indicates that the printer is ready to receive label formats
and/or commands.
In IDLE Mode the Print Button has several different functions:
a) Pressing the button quickly will reprint the last label
b) If the printer was just turned ON and no formats were sent to the
printer, pressing quickly will print the power-up label,
c) Holding the button depressed: Form Feed labels until the button is
released.
224/424 Operator’s Manual - 880027-1000 3-7
Getting Started Chapter 3
3.5.2 Halted Mode: RED
The printer is in the HALTED Mode when it has stopped due to an error condition. The
Status Indicator Light will be solid red in color when the printer has entered the HALTED
Mode. The printer will remain in this mode until the error has been corrected and cleared.
Once the error has been cleared, the printer will attempt to execute the previous format
and/or commands.
3.5.2.1 Steps to clear the >STOCK OUT< error
a) Load new label media.
b) Press the Print Button quickly to start printing.
c) Press the Print Button until label is properly registering on media.
d) Press the Print Button again during printing to resume batch printing.
3.5.2.2 Steps to clear the >STOCK OUT< error with “E-Z Out function”
If Soft Switch #5, Bit #1 is set to “1”, then a single quick press of the Print
Button will clear the >STOCK OUT< error once the printer has more label
media loaded.
3.5.2.3 Automatic Stock Eject on >STOCK OUT<
The printer performs an Automatic Stock Eject operation whenever it runs out
of label media. As soon as the >STOCK OUT< condition is detected, the
printer feeds the label media forward to clear the drive roller.
The feed distance is just enough to eject the last of the label media past the
drive roller and then stop. This happens automatically, the user doesn’t have
to hit the Print Button.
3.5.3 Paused Mode: Solid or Flashing AMBER
There are several ways that the operator can control the output of the printer. The printer
will display either solid or flashing AMBER depending upon the mode of operation. Also,
the printer will display a solid AMBER during a FLASH operation.
Solid AMBER A printed tag/label is waiting to be taken by the operator when the
printer is in a Tag/Tear (^D97) or Peel-and-Dispense (^D98) mode.
The printer is in the FLASH mode.
Flashing AMBER Pressing the Print Button during tag/label printing will pause printing. It
will resume printing by pressing the Print Button again.
3.5.4 Diagnostic Mode
The Diagnostic Mode temporarily powers up the printer using factory default parameters.
Also, the printer’s current user configuration parameters and statistical information are
printed out on a Status Label. This provides useful information to help diagnose and
troubleshoot problems. The printer will use the factory default parameters until the printer
has been reset using a soft reset or by cycling power. The printer will then return to the
configuration shown on the Status Label.

3.5.4.1 Entering Diagnostic Mode
To enter the Diagnostic Mode, press and hold the Print Button “IN” while turning the printer
“ON.” Release the Print Button after printer begins to print the Status Label. The printer will
enter the DIAGNOSTICS Mode, and print the Statistics label and a print test pattern.
In the DIAGNOSTICS Mode, the printer is forced to use the RS-232 port at 115,200 baud.
The normal Soft Switch settings are ignored, and factory default settings are loaded into the
printer. These default settings will remain in effect until the printer power is cycled or a Soft
RESET command is issued (^D32). These are the only 2 ways to get out of the
DIAGNOSTICS mode.
3.5.4.2 Statistics Label
The Statistics Label may be printed either by entering the DIAGNOSTICS Mode or sending
the Printing Statistics Command.

Chapter 4: Designing Labels Using LDS
Label Design Software (LDS) refers to the control language resident in the printer used to
create labels. All bitmapped fonts, character sets and bar codes are resident in the printer.
Additional fonts and graphic images may be sent from a host and stored in the printer’s
memory.
A label format is produced by a series of 5 steps:
1. Control commands to define printer operation.
2. A format header to define the label height, width, print speed, etc…
3. Field data that defines the placement of text, bar codes, graphics or lines.
4. Actual text data to place in the Field data strings.
5. Control commands to initiate printing.
4.1 Control Characters
Throughout this manual there are references to control characters. In order to print them in
this manual, they have been written using standard characters and icons. Escape
characters are represented by <ESC> and a carriage return is represented by <CR>. It is
important to note that all printer functions, unless otherwise noted, must be followed or
terminated with a carriage return (<CR> or HEX OD).
Note: Control codes are ignored when the printer is configured to accept binary
compressed files (^D23).
4.2 LDS Design Exercises
There are many different machines capable of sending information to the printer including
main frames, mini-computers, special purpose computers and PC’s. For the purpose of
simplicity, the design exercises contained in this manual will use one of the easiest methods
by using an IBM compatible PC and a VT-100 terminal emulation software program. This
method of connection will allow two-way, serial communication with the printer.
Items required:
- A computer with at least one unused serial communication port (COM1, COM2…).
- A serial interface cable.
- A VT-100 terminal emulation program such as HyperTerminal™.
- A text editor that does not add formatting characters such as Microsoft® Notepad.
4.2.1 PC Connection (Serial)
The printer is shipped with serial communication parameters set to 115200 bits per second,
no parity, 8 data bits, and 1 stop bit (115200-N-8-1). This means that for proper
communication, the PC’s communication port must be set to these parameters. If a terminal
program is not available, it is possible to send files to the printer using the DOS COPY (for
example: C:\>COPY FILENAME COM1) command. When using DOS, it is a good idea to
set the communications port up using the DOS MODE (for example: C:\>MODE
COM1:9600,n,8,1,p) command before copying the files to the port. Create a text file, enter
“^D3” <CR> (carriage return) and save it as “D3.txt”. Send the file to the printer by either
using the DOS COPY (C:\>copy d3.txt com1) command or by using a terminal program.
224/424 Operator’s Manual - 880027-1000 4-1
Designing Labels Using LDS Chapter 4
Figure 4-1 HyperTerminal™ Window Example
4.2.2 Format Creation
Special Control code functions (see Chapter 5, Special Control Codes) and/or label formats
may be entered directly through the keyboard but this is not the most efficient method if
entering a large amount of data or numerous commands. Large formats and/or numerous
commands should be entered in an ASCII text editor and then uploaded to the printer.
Microsoft® Notepad has been used for the creation of label designs in this manual because
it is simple to use and does not add formatting characters.
The LDS programming language uses thermal dots as the unit of measure. All commands
and parameters, unless noted otherwise, should be entered using dots. The 224 and 424
printers may be fitted with either a standard density 203dpi head, or a higher density 300dpi
print head.
These are the conversion values for each print head:
Print head Dots/mm Dots/inch Inch/Dot
203 8 203 0.0049
300 12 300 0.0033
EXAMPLE: To enter the width of a label that is 2” wide when using a 203dpi head, the
value entered would be 406 (2” x 203 dots/in. = 406).
The printer can accept either the one-character control code (“Ctrl + E” (HEX05)) or the twocharacter caret (^) plus alpha character (“^E”). In other words, for a PC keyboard, the same
command can be generated either by holding down the “Ctrl” key and pressing the alpha
character or by entering the two characters; the “^” (the character generated when you
press the “Shift” key and the “6”) plus the alpha character. See Chapter 5 for additional
information regarding control codes and printer commands.
4-2 224/424 Operator’s Manual - 880027-1000
Chapter 4 Designing Labels with LDS
There are some special features offered by the printer that assist in label design. For
example, the auto-size command (^A2^D39 <CR>) provides most of the header format
information needed to define the different properties of the media being used. The current
state of the printer is accessed through the enquiry command (^D5 <CR>, Ctrl E, or 5 NULL
characters + 01 (HEX 00 00 00 00 00 01) if binary compression has been enabled). The
statistical information of the printer is made available through the use of the ^A0^D29 <CR>
or more simply ^D29 <CR> command.
The following sections of this chapter are intended to provide the user an overview of the
LDS language. The overview will include information regarding the label format, header
definition, and list the different types of field information available. The combination of these
sections and Chapter 5 should provide the user with the information required for easy format
creation and printing. Once some understanding of these basic concepts has been
achieved, use the Quick Reference Guide in Appendix C for expedient label design.
4.3 Label Design: An Overview
A label format consists of a header record and field records, followed by the text data to be
printed. The records describe how the label is to be printed. The header contains
information about the label itself such as label height, width, print speed, etc. The field
records refer to the data section and contain information about positioning coordinates, and
the type of character generation such as text, graphics, bar codes, etc. The number of
fields is limited only by the amount of free memory available.
Below is a sample label format created for the Model 424 with a 300 DPI print head. We will
refer to this format as we break down the steps and components to produce the format.
Refer to Figure 4-2 for a printed representation.

Corporation <CR> Text data string #2.
Thermal Printing Solutions <CR> Text data string #3.
012345 <CR> Text data string #4.
^D3 <CR> Print label.
The command ^D57<CR> on the first line informs the printer that a format is coming and
causes the printer to enter the format entry mode.
The next line is the header information that sets the label size and other pertinent
information.
224/424 Operator’s Manual - 880027-1000 4-3
Designing Labels Using LDS Chapter 4
The next five lines are layout and configuration for each data field in the format.
The command ^D56<CR> selects the user’s layout or more simply the end of the formatting
information.
The command ^D2<CR> instructs the printer to start accepting data for each of the defined
field’s strings that are entered into the previous format received (between the ^D57 and
^D56 commands). Field #1 defines the placement and configuration for Text Data String
#1; Field #2 defines the placement and configuration for Text Data String #2, etc… The
label is printed from the bottom left corner to the top of the label.
The next three lines are the text data for the associated field format lines.
Text Data String #4 is being accessed twice. The format places the Text “012345” on the
label and then is accessed again placing a Code39 symbol representing “012345” on the
label.
The command ^D3<CR> instructs the printer to print.

4.4 Label Header
The label header consists of eleven parameters that control the media layout as well as
printer configuration. A comma (,) delimiter is used to separate the parameters and a
carriage return is required to terminate the header.
The values for header elements requiring measurements are expressed as thermal dots or
pixels. Dot or pixel size varies depending upon the print resolution of the print head. Two
print resolutions are currently available for the 224 and 424 printers (203 DPI and 300 DPI).
The dot size of a 203 dots per inch head (8 dots/mm) is 0.0049”. The dot size of a 300 dots
per inch head (12 dots/mm) is 0.0032”. The dot size is the same in both the horizontal and
vertical direction. For example, a 4” X 6” label printed with a 203 DPI print head would be
4-4 224/424 Operator’s Manual - 880027-1000
Chapter 4 Designing Labels with LDS
812 (4 X 203) dots in the horizontal or “X” direction, and 1218 (6 X 203) dots in the “Y”
direction.
While the maximum number of dots in the horizontal or “X” direction is limited by print head
size, it is virtually unlimited in the vertical or “Y” direction. Vertical dot rows are “stepped” by
the drive roller motor.
This is a list of the header element mnemonics for the sample label in Figure 4-2:

4.4.1 HFM (Number of Fields in Layout)
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD, SPG, OFX, OFY
This parameter is used to specify the number of fields in the layout. If more format fields are
defined than specified in the HFM parameter, they will be ignored and will not print. The
HFM was set to a value of 5 in the format used to create the sample in Figure 4-2. This
means that a total of five format fields are to be generated. If the HFM were changed to 4,
only the first four format fields would be generated.
4.4.2 LSX (Print Head Size X)
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD, SPG, OFX, OFY
This parameter is used to specify the width of the print head using dots as the unit of
measure. The maximum width of the LSX parameter is determined by the width of the print
head. LDS has been specifically designed to accommodate a variety of print head widths.
These are the LSX values that should be used for proper print registration with various print
heads:
Print Width Dots/Inch # of Dots (LSX Value)
2.207” (56.05 mm) 203 448
2.133” (54.186 mm) 300 640

Table 4-1 Valid LSX Values
4.4.3 LSY (Label Size Y)
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD, SPG, OFX, OFY
This parameter is used to specify the height of the label using dots as the unit of measure.
The maximum height is virtually unlimited and is dependant only with available printer
memory. The label sample (Figure 4-2) LSY measures 3” or 900 dots.
4.4.4 WEB (Web Size)
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD, SPG, OFX, OFY
The WEB parameter is the width, measured in dots, of the webbing or backing material that
is found on the left side of a die-cut label. This parameter is used to introduce an offset to
accommodate the backing of die-cut media. The label sample (Figure 4-2) WEB measures
.0625” or 20 dots.
4.4.5 GAP (GAP Size)
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD, SPG, OFX, OFY
This parameter is the height, measured in dots, of the registration mark used to identify the
beginning of a label. The label sample (
Figure 4-2) GAP measures 0.123” or 40 dots.
4.4.6 DPS (Print Speed)
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD, SPG, OFX, OFY
The DPS parameter is used to set the printing speed for the printer. Refer to
the list of print speeds, DPS values, and corresponding inches per second values. To print
at greater speeds, change the DPS value to a lower setting as shown on Table 4-2.
Table 4-2 for

4.4.7 LCB (Label Control Byte)
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD, SPG, OFX, OFY
This parameter selects the method the printer uses for detecting registration marks on the
different media types. The Model 224 and 424 printers have both upper (transmissive) and
lower (reflective) gap detectors as standard equipment. The following sections discuss the
LCB settings for the different media types.
4.4.7.1 Die-Cut and Blow-Hole Media (setting = 0)
A selection of “0” in the LCB parameter instructs the printer to detect the leading edge of a
die-cut label or a “blow-hole” to identify the start of the next label. In this method light from
the lower sensor passes through the stock to the detector in the upper sensor. This is
224/424 Operator’s Manual - 880027-1000 4-7
Designing Labels Using LDS Chapter 4
referred to as “transmissive” sensing. The label sample (Figure 4-2) is die-cut, therefore,
the LCB is set to “0”.
4.4.7.2 Continuous Media (setting = 2)
If the LCB parameter is set to a value of “2”, the printer will not search for a registration
mark. The gap detectors are only used for stock out conditions when set for continuous
media types. The printer will print all fields that contain data and then advance the media by
the amount specified in the SPG parameter of the header when the default AGD of “1” is
entered in the header. This means that fields that are left blank or text data for the
associating format fields that are left empty will not print.
For example: Imagine a receipt format that contains 100 lines. If data is provided for the
first 50 lines, the printer will not advance for the remaining 50 lines that have been left blank.
The printer would stop immediately after printing the 50th line and then advance the media
by the amount specified in the SPG header parameter.
When the AGD header parameter is set to “0”, the printer will advance the same amount of
media even when text data fields are left blank. In this case, the advance distance is
determined by adding the SPG parameter and LSY parameter values.
For example: Imagine the same format as mentioned above that has an LSY value of 609
(3” x 203 = 609), an SPG value of 285, and an AGD value of “0” that contains 100 format
lines. If text data is provided for the first 50 lines and the remaining 50 lines are left empty,
then the printer will print the first 50 lines, advance the next 50 lines, advance the remaining
LSY value, and then finally advance the SPG or 285 dots. Regardless of the format fields, if
the LSY is set to 609 and the SPG is set to 285 the printer will advance a total of 881 dots
(609+285=881).
4.4.7.3 Black Line Media (Reflective) (setting = 3)
The Reflective Black Line method is used when media using a black line for a registration
mark and reflective detection is desired; a “3” should be entered in the LCB parameter. This
setting will detect the leading edge of the black line by using the lower sensor only. The
light from the emitter in the lower sensor is reflected down to the detector in the lower
sensor. This method is the preferred method for detecting media containing a black line
and should be used whenever possible.
Note: The detector in the upper sensor is still used to detect a “paper out” condition.
4.4.8 AGD (Activate Gap Detector)
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD, SPG, OFX, OFY
This parameter selects the number of step (dot rows) that the printer should skip before gap
sensing is activated. This value is usually set to “1”. It is a good idea to set it to a value to
ignore areas of pre-printed or perforated stock that might cause incorrect gap detection.
4.4.9 SPG (Steps Past Gap)
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD, SPG, OFX, OFY
This parameter is used to specify the number of steps (thermal dots) to advance the media
after a registration mark has been detected. This parameter is required to properly register
4-8 224/424 Operator’s Manual - 880027-1000
Chapter 4 Designing Labels with LDS
print on each label. The table below lists proper SPG settings for particular printer
configurations when the LSY is greater than the parameter value.
Model/Print Head DPI D2G Value
224/424 – 203 DPI 468
224/424 – 300 DPI 730
Table 4-3 Dot to Gap Parameters
For media that has a LSY value less than the parameter value in table 4-3, the SPG will
need to be calculated. SPG can be calculated using this formula:
SPG = (D2G + LSY - DRM) mod (LSY + SBL)
NOTE: All values are in pixels or dots.
D2G = This is a physical distance from the registration sensors to the print head's dot row,
and is a specific value for each model.
LSY = This is the actual height of the media in pixels or dots.
DRM = The Distance to Registration Mark is the distance from the leading edge of the
printable area to the beginning of the registration mark.
SBL = The Space Between Labels is the non-printable distance between the media,
typically found on die-cut labels. If the media contains space between the actual
printable portions of the media being used, this would be the SBL parameter.
Please note that this does not reflect a blowhole or black line height, as these
registration marks are typically positioned within the printable area. When die-cut
media is used, this value is also used in the GAP header parameter.
Calculation Examples:
Die-cut Media:
A 424 203 DPI printer being used with 3" x 1" media containing a .125" die-cut gap. The
SPG would be calculated as follows:
SPG = (D2G + LSY - DRM) mod (LSY + SBL)
SPG = (468 + 203 - 203) mod (203 + 25)
SPG = 468 mod 228
SPG = 12
D2G (468) = The Dot to Gap distance for a 203 DPI 424 printer (Table 4-3).
LSY (203) = The height of the printable area; 1" x 203 DPI = 203 dots.
224/424 Operator’s Manual - 880027-1000 4-9
Designing Labels Using LDS Chapter 4
SBL (25) = The Space Between Labels, or die-cut GAP in this case;
.125" x 203 DPI = 25 dots.
DRM (203) = The Distance to Registration Mark is from the leading edge of
the printable area to the next registration mark;
1" x 203 DPI = 203 dots.
The SPG can be fine adjusted by temporarily adding a line at dot row #1 using Line Draw
and adjusting the SPG number up and down to get desirable registration.
4.4.10 OFX (Offset X Direction)
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD, SPG, OFX, OFY
This parameter is used to move or offset all format fields in the X direction without altering
the format fields coordinates themselves.
4.4.11 OFY (Offset Y Direction)
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD, SPG, OFX, OFY
This parameter is used to move or offset all format fields in the Y direction without altering
the format fields coordinates themselves.
4.5 Sample Header
This is the header for the format used to generate the printed sample in Figure 4-2 followed
by a summary of the header values.
5, 1280, 900, 20, 40, 7, 0, 1, 405, 0, 0 <CR>
5 = 5 format fields are following the header.
1280 = LSX (total print head dots) is 1280 dots.
900 = LSY (label height) measures 3” or 900 dots.
20 = WEB measures 0.0625” or 20 dots.
40 = GAP measures 0.123” or 40 dots.
7 = Print speed (DPS) of 7 = 4.5 inches per second.
0 = LCB of 0 for die-cut labels.
1 = AGD of 1 step.
405 = SPG of 405 for proper placement of the next label.
0 = No X offset.
0 = No Y offset.
<CR> = A carriage return must follow the header.
4.6 Label Format Fields
The Label Format Fields are used to define the characteristics, placement and
representation of the corresponding text data of the individual fields. A format field is
broken down into many different parameters. It is not necessary to enter values for all of the
parameters (default value will be used if a parameter is left blank) but each parameter must
be separated with the comma delimiter (“,”). A carriage return must follow each format field
for proper operation to occur. The values entered must be positive integers for all of the
parameters of the format field.

4.6.1 TSN (Text String Number)
The parameter determines which line of text data will be used for formatting. This allows for
more than one field to use the same text data. A TSN of “1” accesses the first line of data.
A TSN of “2” accesses the second line of data, and so forth. The text data is the text that
follows the “^D2<CR>” command in the label’s layout. A graphic image field must point to a
text string that contains at least one character. The maximum value for a TSN is 65536.
224/424 Operator’s Manual - 880027-1000 4-11
Designing Labels Using LDS Chapter 4
4.6.2 XB (X Beginning Coordinate)
The X coordinate of the field is measured in thermal dots. The far left edge of the print
head, as viewed from the front of the printer, is X coordinate “1”. There is no X coordinate
of “0”. The X coordinates increase in size from the left to right. An XB of 300 would place
the field one inch from the left side of the print head. Any offsets required for media that is
not as wide as the print head must be manually entered for the XB or the OFX header
element may be used.
Example: The print head is 1280 dots, if 3” or 900 dot wide media was used, the offset of
190 should be added to each XB coordinate.
Offset example: 1280 - 900 = 380; 380/2 = 190.
4.6.3 YB (Y Beginning Coordinate)
The Y coordinate of the field is measured in thermal dots. A YB of 1 would be the bottom
edge of the label as viewed front the front of the printer. The Y coordinates increase in size
from the bottom to the top of the label. A YB of 300 would place the insertion point one inch
from the bottom of the label.
4.6.4 CC (Character Count)
This parameter determines the number of characters that will be used by the format field. If
the number of characters in the selected text string is greater than the quantity specified by
the CC, the remainder of the text string will be ignored. If the text string has less than the
number specified by the CC, then only those characters defined by the text string will be
printed. For example, the text string “character count” should have a CC of “15” including
the space character. This parameter should be set to a value of “1” if the field is a graphic
image.
4.6.5 TCI (Text Conversion Identifier)
The TCI parameter determines how the text string will be printed. The TCI is used to select
text, bar codes, lines, downloadable font, or graphics. All of the TCI values used by the
224/424 printer are listed in
data “012345” would print the text “012345” while a TCI of “15” would produce an
“Interleaved 2 of 5 symbol”.

4.6.9 CMX (Character Multiplier X Direction)
The CMX parameter multiplies each character in the X direction. The valid range is 1 to
65536. For bar codes with a FO of 0 & 180 degree rotation, the CMX would be the
multiplier while the CMY would be the actual height in thermal dots. For bar codes with a
FO of 90 & 270 degree rotation, the CMX would be the actual height in thermal dots while
the CMY parameter would be the multiplier.
4.6.10 CMY (Character Multiplier Y Direction)
The CMY parameter multiplies each character in the Y direction. The valid range is 1 to
65536. For bar codes with a FO of 90 & 270 degree rotation, the CMY would be the
multiplier while the CMX would be the actual height in thermal dots. For bar codes with a
FO of 0 & 180 degree rotation, the CMY would be the actual height in thermal dots while the
CMX parameter would be the multiplier.
4.6.11 CS (Character Spacing)
This parameter adjusts the spacing between each character. If this parameter is omitted,
then the default for the selected character generator (CGN) is used. The values (0-127) add
dots while (128-255) subtract dots. For example, a value of 4 would insert 4 dots between
the characters while a value of 131 would subtract 4 dots between the characters. Bar
codes have default spacing according to the indicated multiplier. Multiplying a text string will
not multiply the spacing between characters. This element may be used to properly space
the characters to create the desired printed effect.

Designing Labels Using LDS Chapter 4
4.6.12 TSP (Text Starting Position)
This parameter marks the starting position of the character in the text string to be used as
data. This is useful for allowing several fields to use sections of the same text string,
minimizing the amount of data transmitted. For example, for the text string 0123456789, a
TSP of 5 and a CC (Character Count) of 2 would print 45.
4.6.13 ,,, (Reserved Spaces)
These are spaces reserved for future use and nothing should be entered between the
comma delimiters.
4.6.14 AN (Attribute Number)
The AN parameter has four different effects. If set to a value of “0” the character spacing is
proportional. Reverse Text (white on black) is created by setting the AN to a value of “1”
and printing a black box on top of the text using the Line Draw function. (Special Note: The
AN parameter of the line field should also be set to a “1” for proper reverse imaging.) If the
AN parameter is set to a value of “2”, the character spacing will be fixed / non-proportional.
A setting of “3” will print both fixed/non-proportional character spacing and reversed text.
0 Proportional Character Spacing
1 Reverse Video
2 Fixed / Non-proportional Character Spacing
3 Fixed / Non-proportional Character Spacing and Reverse Video
8 True Reverse Video: Character cell = BLACK, Character = WHITE
4.7 Line Draw
It is possible to design lines into a label utilizing some of the elements of label format fields.
Specifically, a TCI value of “6” enables the line draw function. XB and YB provide a starting
position for a line draw. CMX and CMY provide length and thickness to a line. Other
elements not necessary to draw a line such as CC, CGN, FO, FJ, CS, and AN are ignored
by simply adding delimiters (commas) without values.
An example of two lines drawn on a label is shown in Figure 4-5. This 3 x 3” label was
designed for a 424 printer with a 300 DPI print head.

properly. “Line” was used in the example to clearly define the label format fields that contain
line values. However, it could have simply been one character such as a period “.”

4.8 Reverse Video
The printer has the ability to produce Reverse Video by printing white text over a black
background. Two methods are used to produce this effect. The advantages and
disadvantages are covered in greater detail in the following two sections.
4.8.1 Reverse Video
The first method (Reverse Video) is to place text over a black box created with line draw.
When the label format defines print at the same coordinate twice the printer will not print
creating a reverse print effect when the Attribute Number (AN) is set to “1” for the Label
Format Fields defining the line draw and the text fields. The size of the box is not defined
by the text. Adjustment to the size of the box must be made by adjusting the line draw
coordinates.

Chapter 5 Printer Commands
The 224 and 424 printers have a large and versatile collection of control commands to meet
the special needs of labeling applications. Most of the commands use the “^D” control
sequence, however the printer also recognizes a selected number of other control
sequences.
For all commands listed in this manual, the printer will recognize the one character control
code (“Ctrl+D”) or the two-character caret plus alpha character (“^+D+<CR>”) sequence. In
other words, the same command may be generated by either holding the control (Ctrl) key
down and pressing the alpha character or by entering the two characters – the ^ (caret,
generated when the “Shift” key is pressed and then the “6” key) and then the appropriate
alpha key (upper and/or lower case).
Unless specified otherwise, commands are entered by sending the ^Dxx command where
xx is the command number. The ^D commands are terminated by either issuing a carriage
return after the command or by issuing another command and/or control code. Some
commands load data or control numbers and are preceded by the ^Axx command. The xx
specifies the value and/or control number for the associating ^D command. The ^D
commands should precede or follow the actual format layout. They should be placed before
the ^D57 or just before the ^D3 print command.
To protect against errors, in situations where the two-character caret and alpha sequences
are used exclusively as printer commands, the control character recognition may be
disabled. This is accomplished by using the ^D93 command or by using the ^D21
command to setup Soft Switch #1 Bits #1 & #2.
Some mainframe and mini-computers cannot use the ASCII “^” character. In these cases,
substitute the ASCII pipe symbol (“|”) or use the one-character control code representation.
5.1 Special Printer Control Codes
To perform special functions, the printer uses the following control characters. All other
control characters will be ignored. Some of these instructions are also accessible through a
“^D” command sequence and will be noted as such.
^A Accumulator Mode: Used to supply the parameters for the ^D commands.
These parameters must be positive integers and are generally decimal
numbers but may be entered as binary if the ASCII “B” precedes the value or
parameter. For example, “^AB00000001^D21 <CR>” may also be entered as
“^A1^D21 <CR>” as well.
^B Text Entry Mode: Instructs the printer to enter printable text entry mode.
This command (or the preferred “^D <CR>”) must be sent before the text
string information. This command is the equivalent of the “^D<CR>” sequence
but does not require the carriage return (^B text string data). Because the
“control B” is shorter, it is easier to use in direct terminal mode. In general it is
224/424 Operator’s Manual - 880027-1000 5-1
Printer Commands Chapter 5
better to use the ^D2 command sequence inside a file or program to assist in
trouble-shooting the format.
^C Print: Starts the print cycle or batch. This command is the equivalent of the
“^D3<CR>” command sequence but does not require the carriage return.
Because the “control C” is shorter than the ^D3 command sequence it is
easier to use in direct terminal mode. In general the ^D3 sequence is better to
use inside a format and/or program to assist in trouble-shooting the format.
^D Command Mode: Used to issue commands to the printer. This command is
normally preceded by the ^A sequence. The ^D commands must be
terminated with a carriage return or another command sequence
(^A9^D73^D3<CR> is the same as ^A9^D73<CR> and ^D3<CR>).
^E Printer Enquiry: This command is used to attain the current status or
operational state of the printer. The “^E” does not require a carriage return
and is the equivalent to the “^D5<CR>” command sequence. If Binary
Compression is enabled (default setting) the ^E and ^D5 commands will not
function. Five NULL characters (HEX 00) followed by a SOH (Hex 01) are
required to get the printer’s status. (00 00 00 00 00 01) See 5.1.1 for
additional information regarding the Printer Enquiries.
^M Terminate Text or Data String: This command is the equivalent of the
carriage return character and is used to terminate commands and format lines.
^H Delete: This control code is used to delete the last printable character when
communicating to the printer through a keyboard via a terminal. The ^H is the
equivalent of the “Backspace” key on the keyboard.
^K Print Test Pattern: Used to generate a test pattern which consists of a series
of diagonal lines. The pattern is helpful in determining the condition of the
thermal dots on the print head. The ^K code is the equivalent of the “^D11
<CR>” command sequence.
^L Form Feed: Used to feed one blank form based on the previous format
configuration parameters. This command is the equivalent of the “^D12
<CR>” command sequence.
^Q XON: Instructs the printer to send data or resume sending data.
^S XOFF: Instructs the printer to stop sending data.
5 NULLS + 01: The 5 NULL method commands are a way to pass commands to the
printer even when the printer is configured in binary compression mode. The
command is sent to the printer as HEX characters; 00 00 00 00 00 01 are sent
to the printer in order to issue the command. This command is used to request
the printer’s status and is very similar to the ^E command. The biggest
difference between this command and the ^E is that when printers are
configured for binary compression (D23 -SW3 bit 7), which is required if saving
graphics, the ^E will not function. This means that if the printer is going to be
5-2 224/424 Operator’s Manual - 880027-1000
Chapter 5 Printer Commands
using binary compression, the 5 NULLs method should be used to request
status instead of the ^E command.
5 NULLS + 02: The 5 NULL method commands are a way to pass commands to the
printer even when the printer is configured in binary compression mode. The
command is sent to the printer as HEX characters; 00 00 00 00 00 02 are sent
to the printer in order to issue the command. This command is used to cancel
pending jobs/commands and to remotely clear errors returning the printer to
an idle >READY< state. If the condition causing the original error condition
still exists, sending new jobs will cause the printer to go back into an error
condition. This command simply provides the ability to remotely clear error
conditions and return the printer to a state that allows normal communication.
5 NULLS + 0F: The 5 NULL method commands are a way to pass commands to the
printer even when the printer is configured in binary compression mode. The
command is sent to the printer as HEX characters; 00 00 00 00 00 0F are sent
to the printer in order to issue the command. This command instructs the
printer to exit the temporary binary mode switch. If a printer has been
configured to use binary compression mode using the soft switch command
(D23 - SW3 bit 7), the 5 NULLs +0F method will be ignored when issued.
0F + 5 NULLS: The 5 NULL method commands are a way to pass commands to the
printer even when the printer is configured in binary compression mode. The
command is sent to the printer as HEX characters; 0F 00 00 00 00 00 are sent
to the printer in order to issue the command. This command provides a
temporary switch into binary compression mode without having to have the
printer configured for binary compression (D23 -SW3 bit 7) mode. This is
helpful when placed just before a graphic file. The printer will continue
processing the data as binary data until instructed to exit the temporary binary
mode (5 NULLs + 0F).
5.1.1 Enquiry Responses
It is important for the host computer to know the status of the printer as labels are being
produced. This facilitates security in the system and flags electrical, mechanical, and
functional error conditions. Enquiries also aid the system designer in adjusting the pace of
the printer with that of the operator.
The printer returns enquiry responses to the host in two different modes depending on how
Software Switch#1 is configured.
Text Mode: The response is sent to the host as text as shown in
are sent out the active communication port with a CR LF separating each one. The end of
the response is terminated with an extra CR LF.
Byte Mode: The response is sent to the host as a hexadecimal number (byte) as shown in
Table 5-1. Each string is represented by a single byte with nothing separating them. The
end of the response is terminated with a FFh character.

5.2 Basic Printer Configuration Commands
The following commands are used to set up basic printer configuration. Most of these
commands are non-volatile, and therefore do not need to be present unless changes are
desired. Changes made with these commands will not take effect until the printer’s power is
cycled “OFF” and “ON,” or a “soft reset “ command (^D32 command) is sent to the printer.
Note: When the printer is in the DEFAULT MODE, factory settings control printer operation.
This provides a starting point for re-establishing communication (factory default baud rate is
115,200) with the printer so that user settings can be reset should settings become
scrambled.
The statistics label printed when the printer is entered into the DEFAULT MODE reflects
current user settings, not factory default settings.
5.2.1 Baud Rate
This non-volatile command changes the serial port communication speed.
Note: Unless otherwise noted, the factory default baud setting is 115,200. The baud
rate will be temporarily set to 115,200 when the printer is in the Diagnostic Mode if
the user setting is different. The user set baud rate will resume after a “soft reset”
(^D32) or cycling the power to the printer.

5 48-466 Emulation Mode: A special limited 466/48-466 LDS
compatibility mode has been developed for the X24/X24M code base.
The objective of this compatibility mode is to allow applications that use
formats and/or commands developed for a Model 48-466 printer to be
sent to a 203 dpi X24 or X24M Model printer with little or no changes
required. This command allows the printer to enable a limited 48-466
emulation feature of the printer. When enabled, the printer will process
a 48-466 data stream and convert the data stream for proper operation
on an X24M printer. The emulation mode uses a lookup table for fonts
stored in flash and does not use the TCI 1 embedded fonts while this
mode is enabled. Please note that the X24 products store fonts in 0
/180 degree rotation and in 180/270 degree rotation. The odd memory
slots denote 0 or 180 degree rotation fonts while the even memory slots
denote 90/270 degree rotated fonts. The flash memory slot locations
are shown below:
48-466 TCI = 1, CGN # X24 Flash Memory Slot

2 3 and 4

5 9 and 10
6 11 and 12
7 13 and 14
8 15 and 16
Table 5-2 48-466 Emulation Fonts
The 48-466 emulation supports unique 48-466 command operations
and will process the data in the same way when technically possible.
These unique operations are briefly discussed below. Please consult
the Model 48-466 Operators Manual for additional information regarding
the command operation.
a) The printer supports the CGN lookup as defined above and in the
48-466 Operators manual when the emulation command is enabled.
224/424 Operator’s Manual - 880027-1000 5-11
Printer Commands Chapter 5
b) The 48-466 graphic structure is used when the emulation command
is enabled and discussed in greater detail the 48-466 Operators
manual.
c) The ^D59 command allows format slots 121 to 128 to be overwritten
to when the emulation command is enabled.
d) The ^Ax^D125 command controls the location of the euro character
as provided in the model 48-466 printers. The euro character which
by default is mapped to location 0xE3 (227 decimal) can be moved
to another location specified by the x if x>0. If x=0 no remapping will
take place and the euro will stay at location 0xE3. Also if the printer
must be configured to use a code page other than the default (0000)
code page.
The 48-466 and X24 code bases are not fully compatible, so the
emulation does have some limitations. The known limitations are briefly
mentioned below:
a) The 48-466 data stream should not use an Attribute Number of 2
(fixed/non-proportional) which is the seventeenth parameter. It is
not technically possible to emulate this model 48-466 feature.
b) The CS value used in conjunction with the AN set to a 2 to produce
a negative kerning effect should be removed and the field defaulted.
This is the 11th field defined in the format lines.
c) Fields that were using an AN of 2 and CS for negative kerning may
require that their placement coordinates are adjusted to produce the
same outputs.
Once these changes are made, the resulting data may be sent to a 48466 and 424M printer to produce the same printed image in most
cases.

connector on the PCB, to change the status of the outputs, and to
configure the inputs to generate immediate errors.
GP INPUTS:
The P17 connector is used for the GP inputs. These inputs are active
high (24VDC) and may be independently controlled.
The ^D150 command is used to report the current status of the inputs.
When issued, the printer will send the host the current status of the 4
general inputs in the form of “>IO 0nH< where “n” is a hex number from
0 to F.
Example: A status of >IO 05H< would indicate that inputs 1 and 3 are
active (24v) and that inputs 2 and 4 are inactive (0v); 05H =
0101(binary).
The ^D151 is a nonvolatile command used to set which GP inputs are
configured to cause an immediate error when active. An immediate
error will immediately stop printing and go into an error condition. Once
the input is inactive, the “error” would need to be cleared before the
printer will continue. The ^D29 statistical listing reports the GP inputs
that are configured to generate error conditions when active and are
listed under the “ERROR INPUT: 0nH” with the value for “n” equaling
the HEX value of the inputs. The inputs equal a binary number with the
inputs in the following order; 4321.
Command Syntax:
^D151<CR>0n<CR>
n = the hex value from 0 to F.
Example: If the application wanted to configure inputs 1 and 3 to
generate error conditions when active, a ^D151<CR>05<CR>
command (the <CR> indicates carriage return characters) would be
issued. The printer ignores the LF characters, so a <CR+LF> is
interpreted as a <CR> as well) would be sent to the printer.
GP OUTPUTS:
The P21 connector is used to provide 4 general purpose outputs.
These outputs provide 24V and may be used to provide the voltage
needed to power the GP INPUTS.
The ^D69 command is used to read and report the current status of the
GP Outputs in the form of “>IO 0nH< where “n” is a hex number from 0
to F. The outputs equal a binary number with the values in the
following order; 4321.
Example: A status of >IO 05H< would indicate that outputs 1 and 3 are
active (24v) and that outputs 2 and 4 are inactive (0v); 05H =
0101(binary).
224/424 Operator’s Manual - 880027-1000 5-13
Printer Commands Chapter 5
The ^D68 is a nonvolatile command used to enable which GP outputs
are active. The outputs are entered in as a HEX value that is equal to a
binary number with the outputs in the following order; 4321.
Command Syntax:
^D68<CR>0n<CR>
n = the hex value from 0 to F.
Example: If the application wanted to configure outputs 1 and 3 active,
a ^D68<CR>05<CR> command (the <CR> indicates carriage return
characters) would be issued. The printer ignores the LF characters, so
a <CR+LF> is interpreted as a <CR> as well) would be sent to the
printer.
NOTE: A status request (^E, ^D5, or 5 NULLs 01) will never show the
status of the outputs while a status request will show the input status if:
1) GP I/O is enabled AND
2) One or more bits have been configured to generate errors when
active AND
3) One or more of those halting bits have gone active and have
produced an error that has not been cleared.
NOTE: If the printer is not in the general purpose I/O mode, the inputs
status may still be read with the ^D150 command but the outputs
cannot be read (or written to) with the ^D69 or ^D68 commands.
NOTE: If an input has caused an error to be generated, then goes
inactive, and another print request received before the error is cleared,
the printer will not print and will remain in the error state. A status
request will show the active error inputs. This condition will remain until
the error is cleared.
NOTE: Default power up will disable I/O mode.

Printer Commands Chapter 5
5.2.3 Set Communication Port Selection Commands
The 224 and 424 printers have 3 different serial communication ports on the rear panel:
1) RS-232D 115,200 bits/sec, max.
2) USB 12Mbits/sec
3) Ethernet (option) 10Mbits/sec or 100Mbits/sec
Only one of the 3 serial ports can be active at any time, but all 3 cables can be connected to
the printer at the same time. In cases where more than 1 cable is connected, the printer
follows specific rules to determine which serial port is the active port when power is applied.
5.2.3.1 Set Serial Port Source Command (Non-volatile- ^D108)
This command sets which serial port will be used the next time the printer is turned ON. The
224/424 printer has three serial data ports on the rear panel: RS-232, USB, or Ethernet.
Only 1 port can be active at any given time. The D108 command sets how the printer
selects the active serial port the next time the printer is powered ON. Settings made with
D108 are saved in the printer’s system parameters and are used to select the serial port on
power-up.
^A ^D Command
X 108 Serial Port Source (Non-volatile)
0 AutoScan: When the printer powers up, it will scan the USB and RS-232
ports and select the “HOT” port. The USB port will be the HOT port if the USB
cable is connected between the printer and a PC that is powered “ON.” The
RS-232 port will be the HOT port if the USB cable is not plugged in and a
character comes in on the RS-232 port. The printer will continue to scan both
ports until one or the other condition is satisfied.
1 Ethernet: This command tells the printer to use the Ethernet port the next
time it powers up.
5.2.3.2 Set Serial Port Source Command (Volatile - ^D109)
This command is similar to the ^D108 command, except the ^D109 command immediately
switches between the 3 serial ports without the need to cycle power. Settings made with
^D109 command are NOT saved on power-down. The printer returns to the original port
setting on the next power-ON.
Note: The AutoScan option is not available with the ^D109 command.

5.2.4 Contrast Adjustment Commands
These commands are used to adjust the darkness of the label print. Print quality will vary
not only with different label stocks, sometimes even in different batches of the same label
stock. It is highly recommended that contrast adjustments be maintained at minimum
settings to achieve desired print quality. Higher contrast settings will reduce the life of the
print head.
5-16 224/424 Operator’s Manual - 880027-1000
Chapter 5 Printer Commands
5.2.4.1 Adjust Contrast Window (Volatile - ^D35)
This command is useful for adjusting contrast for specific label formats where different label
media is used on a single printer. The command can be entered into specific label formats
rather than affecting print contrast on all label formats.
^A ^D COMMAND
XX 35 Adjust Contrast Window: This is a volatile command used to adjust the
contrast window. The range is 1 to 9 of the base (^D36).
5.2.4.2 Adjust Contrast Base (Non-volatile - ^D36)
This command is used to adjust overall contrast on all formats.
^A ^D COMMAND
XX 36 Adjust Contrast Base: This non-volatile command is used to skew the entire
contrast window (^D35). This command has a ^A range of 10 to 200%.
5.2.5 Registration Mark Threshold Commands
While the printer is designed to work with a wide variety of label media, it is sometimes
necessary to adjust the printer’s thresholds in order to obtain proper registration and
operation. The numerical value in which the printer senses a registration mark is referred as
the threshold value.
The Threshold Value may be obtained by using the Auto-Size Label Command (^D39). A
more in-depth explanation of registration mark sensing and adjusting the threshold value is
found in the 428M Service Manual.
^A ^D COMMAND
XX 90 Reflective Detection Threshold: This command is non-volatile and is used
to set the reflective or black line threshold value (0-255) at which the printer
detects a black line used for print registration. The default is set to a value of
100 and should work for most media types.
XX 91 Transmissive Detection Threshold: This non-volatile command is used to
set the transmissive or GAP threshold value (0-255) at which the printer
detects gap and/or blow-hole registration marks. The default is set to a value
of 30 and should work for most media types.
XX 124 Stock Out Threshold: This command is non-volatile and is used to set the
stock out threshold value (0-255) at which the printer detects an out of stock or
>LOW STOCK< error condition. The threshold is typically set to a value that is
80 percent of the transmissive sensor reading when no media is detected by
the transmissive sensor. This value is calibrated at the factory and should not
require adjustment unless the transmissive sensor has been replaced.
X 129 Auto Set Threshold: This command will cause the printer to scroll 1350 dots,
determine the proper threshold value, and set the nonvolatile threshold for
proper registration. The ^Ax selects either reflective or transmissive detection.
0 Automatically sets the transmissive threshold value.
1 Automatically sets the reflective threshold value.

Printer Commands Chapter 5
5.3 Advanced Printer Configuration Commands
These commands are not commonly used.
5.3.1 Print Head Size Commands
The 224 and 424 printers can use a variety of different print head sizes and densities. The
^D78 and ^D79 commands (non-volatile) allow the printer to be setup thru software to drive
different print head sizes and densities. Power cycle or ^D32 is required before command
settings take affect.
Note: When using these commands, the ^D79 command MUST be sent prior to the ^D78
.
Head style Dots/Inch # of Dots Print Width
Medium resolution 203 448 2.207” (56.05mm)
High resolution edge 300 640 2.133” (54.186mm)
Medium resolution 203 640 3.153” (80.08mm)
High resolution 300 960 3.200” (81.28mm)
Medium resolution 203 832 4.095” (104.00mm)
High resolution 300 1280 4.110” (108.416mm)
^A ^D COMMAND
X 79 Set print head dots/inch (dpi). This command sets the dot density of the
print head. This command MUST be sent BEFORE the # of Dots (^D78) is set
with the ^D78 command. The only valid entries are ^A0 for 203dpi and ^A1 for
300dpi as shown in the “Dots/Inch” column in the table above.
XX 78 Set print head number of dots. This command sets # of dots in the print
head. This command MUST be sent AFTER the dot density (dpi) is set with
the ^D79 command. The only valid entries for XX are the numbers in the “# of
Dots” column in the table above.
These are examples of how to use the ^D78 and ^D79 commands:
EXAMPLE #1: How to set the printer for a 640 dot, 300 dpi print head:
^A1^D79<CR> (Sets 300 dpi)
^A640^D78<CR> (Sets 640 dots)
EXAMPLE #2: How to set the printer for an 832 dot, 203 dpi print head:
^A0^D79<CR> (Sets 203 dpi)
^A832^D78<CR> (Sets 832 dots)
5.4 General Purpose I/O
^A
^D Command
XX 110 General Purpose Command.
The printer has a special mode of communication for General Purpose control
environments. Communication is over the Ethernet port and uses the
following protocol.
5-18 224/424 Operator’s Manual - 880027-1000
Chapter 5 Printer Commands
The host sends a command byte to the Ethernet port every few milliseconds.
The printer’s Ethernet interface will pass the command byte on to the printer
only when there is a change, i.e., when there is a new command.
The printer sends a byte of status data to its Ethernet interface using the same
data format, and will only send the data when there is a change in status. The
printer’s Ethernet interface will send the printer status byte to the HOST every
few milliseconds.
This is the command byte configuration:
Command Byte From Host to Printer:
Bit # Function when = “1” Function when = “0”
0 PRINT DON’T PRINT
1 PRINT TEST PATTERN DON’T PRINT TEST PATTERN
2 RESET DON’T RESET
3 not used
4 not used
5 not used
6 not used
7 not used
The HOST only sends the command byte to the printer. The printer’s Ethernet
interface receives this command byte from the HOST and tests it to see if it is
different from the previous command byte. If there is a change, then the
command byte is put into the “xx” of a ^Axx^D110 command and sent to the
printer. Valid values for “xx” are determined from the “Host to Printer” table
above.
The printer sends a status byte to the host every few milliseconds thru its
Ethernet interface. This status byte is sent whether there is a change of status
or not.
Status Byte From Printer to Host:
Bit # Function when = “1” Function when = “0”
0 (LSB) IN RESET or PRINTING NOT BUSY
1 ERROR NO ERROR
2 DOWNLOADING A FORMAT FINISHED DOWNLOAD
3 FORMAT LOADED NO FORMAT LOADED
4 not used

Printer Commands Chapter 5
The General Purpose mode of operation is enabled by Soft Switch #5, Bit #8.
These are the specific commands:
^ABxxxxxxx1^D25 Enable General Purpose Mode
^ABxxxxxxx0^D25 Disable General Purpose Mode
Note that the binary data entry mode is shown in these 2 commands. The
user must set the “xxxxxxx” values to agree with current settings in order to
avoid changing any of the other settings in Soft Switch #5.
Entering General Purpose Mode
Sending the “Enable General Purpose Mode” command will set the printer up
to go into General Purpose mode. The printer will NOT go into General
Purpose Mode until a power cycle occurs to cause the data to be stored in
FLASH memory. This command is nonvolatile, so once the General Purpose
Mode is entered the printer will stay in General Purpose Mode thru
subsequent power cycles.
Exiting General Purpose Mode
A printer that is in General Purpose Mode will stay in General Purpose mode
thru power cycles until the “Disable General Purpose Mode” command
(^ABxxxxxxx0^D25) is issued. The next power-ON after a “Disable General
Purpose Mode” command will cause the printer to leave General Purpose
Mode.
Note: A default power-ON will also take the printer out of General Purpose Mode.
5.5 Synchronous Print Mode
This mode allows the printer to be synchronized to external equipment thru an external
PRINT control line. A second input control line ABORT allows a pending print job to be
terminated. Using this mode allows any label, no matter what size to begin printing
IMMEDIATELY using the print input signal. Printing begins 11 microseconds after the rising
edge of the PRINT control line.
Two control signals are required:
1) PRINT input line (connector P17, Pin #2),
2) ABORT input line (connector P17, Pin #8)
Signal logic levels:
The signals are active high and must be between +15Vdc and +24Vdc to be “1”.
The signals must drop below +10Vdc to be “0”.
To use this mode, follow these steps:
a) Download a label format to the printer. This format should not
have the normal ^D3 (PRINT command) in the format. If the
^D3 is left in the format, an initial label will be printed
regardless of the special input line settings.
a) Send the printer a ^D116<CR> command. This will force the
printer to process the label to the point that the label bitmap is
5-20 224/424 Operator’s Manual - 880027-1000
Chapter 5 Printer Commands
ready to be sent to the print head. After this command is sent
no communications will be possible with the printer until the
next step is completed.
b) To start the print, send a high-going pulse on the PRINT input
line. To ABORT the job, whether printing or not, send a highgoing pulse on the ABORT input line.
c) After the label prints or aborts, the printer will return to its
normal non-sync mode of operation.
The PRINT pulse should go back to “0” before the print ends to avoid a second label being
printed. A 10 millisecond pulse works fine.
Continuous sync mode works like single sync mode except after the label is printed it will
immediately be reprocessed (like the printer received another print command) and will wait
for another print signal on the General Purpose print input. This will be repeated until the
printer gets a paper-out error, which exits all sync modes. This mode provides the fastest
way to reprint a label when the slice buffer and starting slice are set properly (^D94 and
^D92).
The main difference between the two modes is single sync mode prints one label and exits
sync mode. Continuous sync mode allows a user to print as many labels as they want using
the print signal until the abort is received or a paper-out occurs.
^A ^D Command
116 Synchronous Print Mode
0 Exit all sync. modes.
1 Enter single sync. mode.
2 Enter continuous sync. mode.
WARNING! There is NO time-out on this command! Once the printer receives the ^D116
command and is waiting for the PRINT or ABORT pulse, it will wait forever!
5.6 Cutter Configuration Commands

5.6.2 Kiosk Cutter Commands
5.6.2.1 Kiosk Cutter Mode
This is a special mode that can be used to avoid media “curling” when left under the drive
roller for extended time. The printer feeds the media forward a programmable amount (See
^D112) so that the leading edge of the media is out from under the drive roller. This helps
prevent the leading edge of the ticket being curled up by the drive roller, which leads to
paper jams going into the cutter.
These are the steps the printer takes when media is to be printed:
1. Media is retracted from the “Idle” position into the printer,
2. Media is printed,
3. Media is advanced to the cutter & cut.
This mode is useful in Kiosk applications where the media may normally rest under the
driver roller for long times and become curled.
^A ^D Command
XX 111 Kiosk Cutter Mode.
0 Disable Kiosk Cutter Mode.
1 Enable Kiosk Cutter Mode.
2 Enable partial kiosk cut mode.
5.6.2.2 Kiosk Cutter Advance Distance Command
This command sets the advance/retract distance for the Kiosk Cutter Mode. The printer has
normal “default” values that it uses when it is fitted with a standard Microcom cutter. But in
custom applications, the distance between the print head dot row and the cutter blades may
be totally different. The ^D112 command is used to accommodate a non-standard distance.
The distance is measured between the print head dot row and the cutting point on the
cutter. Dimensions are in dot rows, so the count will be dependent on the Dots/Inch (dpi) of
the print head.
Print Head Resolution Inches/Dot
203 dpi .0049”
300 dpi .0033”
Table 5-2 gives the default values that the printer uses to advance the media to the cutter
blades. If these values are not appropriate for a custom application, then the ^D112
command may be used to set new advance/retract distances. This command is nonvolatile.

These dispense commands include Peel-n-Dispense, Tag/Tear, Cutter commands, and
224/424 Operator’s Manual - 880027-1000 5-23
Printer Commands Chapter 5
optional media handling commands as well. The following commands define these types of
operations.
5.10.1 Tag/Tear Operation
This command controls a method of dispensing the media so that the perforation between
labels is positioned on the tear bar or peel edge. Once the label is taken, the label media
retracts and allows proper registration of the next label print.
^A ^D COMMAND
X 97 Tag/Tear Operation:
0 Disable Tag/Tear operation.
1 Advance after every print.
2 Advance after copies count.
3 Advance when idle. (Does not use LPD - retracts stock at next sent label
format.)
5.10.2 Peel-and-Dispense Operation
This command is used when the labels are to be peeled from the backing material. Once
the label is taken, the label media retracts and allows proper registration of the next label
print. It requires the optional Label Present Detector (LPD).
^A ^D COMMAND
X 98 Peel-and-Dispense Operation:
0 Disable Peel-and-Dispense operation.
1 Enable Peel-and-Dispense operation.
5.10.3 Cutter Operation
^A ^D COMMAND
X 99 Cutter Control: This command enables full and/or partial cut operation.
This command works in conjunction with the ^D102 and ^D103 Cut Interval
commands. The ^D95 command is also used with the ^D99 command to
adjust the advance distance to the cutter blades and then retract to the home
position (dot row one).
Note: When doing partial cuts with an LPD, the printer will not proceed until
the LPD sees that the label has been taken. Then after a programmable
delay, the printer will retract and print the next label.
0 Disable Cutter operation.
1 Enable Full Cut.
2 Enable Partial Cut.
3 Enable Full and Partial Cut.
XX 102 Full Cut Interval: Instructs the printer when to issue a Full Cut. The default
value is 1. A value of “1” results in a full cut whenever the copies count is
reached, or after each format if a copies count has not been specified. If this
command is set higher than “1” (maximum of 65536), the printer will full cut
5-24 224/424 Operator’s Manual - 880027-1000
Chapter 5 Printer Commands
when that quantity is reached. This command will not operate if the Cutter
Control (^D99) command is set to partial cut.
^A ^D COMMAND
XX 103 Partial Cut Interval: This command instructs the printer when to issue a
Partial Cut. A partial cut requires the use of a Cutter that is capable of Partial
cuts. A Partial Cut leaves a thin piece of media in the center after the cut
cycle is finished. This small piece of uncut stock holds the media together and
the printer waits until the media is removed before printing the next label. The
default Partial Cut Interval is set to 1. The printer will issue a partial cut, if set
to a 1, whenever the copies count is reached. If set to a value greater than 1,
the printer will partial cut when that quantity is reached. This command only
functions when the Cutter Control (^D99) command is set to allow partial cuts.
Note: A full cut will override a partial cut. The following examples assume that the ^D99
command has been set to 3.
Example #1: If the Full Cut Interval is set to a value of 5 and the Partial Cut Interval
is also set to a value of 5, the printer will issue a Full Cut.
Example #2: If the Full Cut Interval is set to a value of 5 and the Partial Cut Interval
is set to a value of 1, the printer will partial cut after labels 1 through 4 and full cut after label
5.
118 Home Cutter: When this command is used, the printer will cycle the cutter
gear to determine the location of the gear and position it in the home position.
5.10.4 Load Advance/Retract Distance and Load Advance Delay
^A ^D COMMAND
XX 95 Advance/Retract Distance: This command is used in conjunction with the
tag/tear (^D97), peel-n-dispense (^D98), and cutter (^D99) commands. It is
used to adjust the number of steps the printer will advance the media after
printing has stopped and then retract the same distance so that media is not
wasted. While the maximum value is 64,000 steps, it is not recommended that
the printer advance further than one label size. This may create a paper jam
when the label is retracted back into the printer.
XX 96 Load Advance Delay: The ^Axx specifies the amount time, in milliseconds,
that the printer will delay the repositioning or retraction of the media. For
Example, “^A1000^D96 <CR>” would delay for a period of one second.
5.11 Slice Buffer Size and Set Starting Slice Number Commands
^D Command
^A
XX 92 Set Starting Slice Number: This command adjusts the number of
slices (dot rows) generated before the printer starts moving the label stock.
The default is set to 67% of the slice buffer size. Anytime the size of the slice

Printer Commands Chapter 5
buffer is changed (ref. ^D94 command), the Starting Slice # is also changed
automatically to a value that is 67% of the new slice buffer size.
“XX” can be any integer value up to a maximum of the number of slices in the
Slice Buffer (See Table 5-14). If a value for “xx” is entered that is too large for
the print head, the printer will respond with the correct maximum value for the

Print head DPI: 300
Slice Buffer Size: 3 (= 3x64KB = 192KB)
Bytes/slice = 4” x (300 dots/inch) x (1 byte/8dots) = 150 bytes
So a Slice Buffer size of 192,000 bytes can store 192,000/150 = 1,280 slices.
At 300 slices/inch, the buffer can hold 1,280/300 = 4.267” of printing.
Default setting for “Starting Slice #” is 100 slices.

2 88Kbytes (default size)
3 192Kbytes
4 256KBytes
5 320KBytes

This command sets the size of the slice buffer in increments of 64Kbytes. The
default size of the slice buffer is 88Kbytes.
NOTE: Any change to the slice buffer size will also automatically change the
starting slice to a default, which will be 67% of the new buffer size.
Because the printer can be fitted with a variety of different head widths and dot
densities, the actual number of slices that the buffer can hold will be
determined by the number of dots in the print head.

5.12 Auto-Load Media
The 224 and 424 printers provide an easy way for new media to be loaded into the printer
thru the use of the Auto-Load function. When this feature is turned ON, the printer will
sense the presence of new media as the operator is pushing it into the printer, automatically
feed the media into the printer, and then register the media using either the TOF sensor or a
Form Feed operation.
There are two types of Auto-Load:
• Auto-Load with Form Feed
• Auto-Load with Top Of Form.
5.12.1 Auto-Load with Form Feed
This command is useful to load media without having to press the Print Button to start
printing again. The operator must insert the label stock into the printer until it stops against
the drive roller. The printer will automatically begin to turn the drive roller after the stock is
sensed by the gap sensor. A delay may be set from when the stock is first sensed and
when the drive roller starts to turn.
The printer will advance a blank label before starting to print properly registered labels.
These are the steps for Auto-Load with FF:
1. With the head mechanism latched in its normal print position,
the user inserts new media until it stops at the drive roller,
2. The printer senses the new media and waits a
programmable amount of time set by the ^D120 command
(default is 1.5 seconds),
3. After the time delay (if set), the printer advances the media
until the first registration mark is sensed.
4. Label printing will resume if a job is pending.
Set up the printer to use Auto-Load with Form Feed by setting Soft Switch #5, bit #6
to “1”.
^AB00000100^D25<CR>
This command must be used if the printer is not equipped with a TOF sensor.
224/424 Operator’s Manual - 880027-1000 5-27
Printer Commands Chapter 5
5.12.2 Auto-Load with Top Of Form
This command is used on printers that are fitted with a “Top Of Form” (TOF) sensor that can
detect the leading edge of the media. Auto-Load with a TOF sensor prevents the loss of the
first label as in Auto-Load with Form Feed.
Soft Switch #5, bit #3 selects the type of TOF sensor. The TOF may be the standard
REFLECTIVE style, or it may use a TRANSMISSIVE sensor for more accurate sensing.
The TRANSMISSIVE style must be used with certain equipment configurations such as a
Cutter Catch Tray.
These are the steps for Auto-Load with TOF:
1. With the head mechanism latched in its normal print position, the operator inserts
new media until it stops at the drive roller.
2. The printer waits a programmable amount of time as set by the ^D120 command
(default is 1.5 seconds) after it senses the new media to make it easier for the
operator to align the paper,
3. After the time delay, the printer feeds the paper forward until the leading edge of the
media is seen by the TOF sensor,
4. The feed forward stops and then the printer retracts the media a programmable
distance as set by the ^D123 command and stops.
Soft Switch #5, bits #6 & #7 must be set to enter Auto-Load with TOF mode.
^AB00000110^D25<CR>
Note: TOF Error—When the printer cannot complete a TOF, it will stop, the LED will turn
“RED,” and if the queried, the printer will say “>TOF ERROR<.” To clear the error, just hit
the print button once. Another TOF can then be attempted.
5.12.3 Auto-Load Commands
^A ^D COMMAND
XX 120 Auto-Load Delay Selection.
Auto-Load Delay = xx milliseconds (up to a maximum of 5000 milliseconds or
5 seconds).
The Auto-Load Delay is the amount of time that the printer waits after
detecting that media has been put into the printer before it starts feeding it in.
A small amount of delay makes it easier for the operator to get the paper fully
inserted into the printer and properly oriented before paper motion begins.
The default value for Auto-Load delay is 1500 milliseconds (1.5 seconds). The
operator may use this command to adjust the delay to suit individual
preferences. ^A0 turns the delay OFF so that the driver roller is activated as
soon as media is detected. Since this is a volatile command the default
setting will be restored every time the printer’s power is cycled “OFF” and
“ON.”
Example: Have the printer wait 1.25 seconds before feeding paper on Auto-Load.
^A1250^D120
5-28 224/424 Operator’s Manual - 880027-1000
Chapter 5 Printer Commands
^A ^D COMMAND
121 Top Of Form Command.
This command initiates a Top Of Form operation:
a) Media is advanced until the leading edge is detected by the reflective
“Top Of Form” sensor,
b) Media is retracted to place the leading edge of stock under the print
head.
This command is useful when using the Auto-Load with Top of Form
command.
XX 123 Set TOF Retract Distance.
0 Sets the DEFAULT value of 1.084” (203 dpi = 220 steps; 300 dpi = 325 steps).
1 Æ 900 Valid retract distances, measured in dot rows.
When a Top Of Form operation is in process, the paper moves forward
until its leading edge is seen by the TOF sensor. As soon as the sensor sees
the paper, the printer stops the forward motion of the paper and begins to
move the paper in reverse toward the print head. This command sets how far
the media is moved back into the printer after the leading edge is seen by the
Top Of Form (TOF) sensor.
Example: ^A223^D123 would increase the retract distance on a 203 dpi printer to
1.099.”
5.13 Printing Commands
The following commands initiate printing, define the number of labels to be printed or control
how the printer initiates printing. All of these commands are terminated by either a carriage
return or by issuing another command or control code.
5.13.1 Basic Printing Commands
^D COMMAND
^A
3 Print Command: (Equivalent ^C) Informs the printer to print a single label or
start printing a batch of labels. Since commands are processed in the order
they are received, this is typically the last command in the format file. This
command is equivalent to the “^C” control code.
5 Send Printer Status: (Equivalent ^E)
8 Cycle Cutter: If a cutter is installed on the printer, this command will cause
the cutter to be cycled. The cutter’s operation will be determined by the D99
command.
If the cutter is a rotary cutter, it will always cycle in the forward direction to
make a full cut.
If the cutter is a guillotine cutter, the cycle direction will be determined by the
last setting given with a D99 command.
224/424 Operator’s Manual - 880027-1000 5-29
Printer Commands Chapter 5
^A ^D COMMAND
11 Print Test Pattern: (Equivalent ^K) Prints a label with diagonal lines that is
used in determining the condition of the thermal dots of the print head. This
command is equivalent to the “^K” control code.
12 Form Feed: (Equivqlent ^L) Prints or scrolls a blank form based upon the
previous format definitions. This command is equivalent to the “^L” control
code.
70 Clear Commands 73-76: Resets the ^D73 through ^D76 commands to their
default values.
XX 73 Load Copies Count: Instructs the printer to print multiple copies without
incrementing serial numbers. This command can be used in conjunction with
the ^D75 (Load Label Count) to allow duplicate copies to be made within a
batch of labels. For example, the following command string will print a total of
150 labels; three copies of each serial number for the 50 different labels.
(^A3^D73^A50^D75^D3<CR>)
1 74 Infinity Print: Prints a batch of labels until the printer is turned off. This
command is most effective when used in conjunction with the Tag/Tear and
Peel-n-Dispense modes. The “^A1” enables the Infinity Print while a “^A0” will
disable this function.
XX 75 Load Label Count: Instructs the printer to print a batch of labels using the
serial number function if enabled. If the serial number function is disabled, the
^D75 command will print the number of copies (the same label) specified by
the “^Axx” sequence just like the ^D73 command. This command may also be
used in conjunction with the ^D73 command. The batch of labels is printed
once a ^D3 command is executed; therefore the ^D75 command must be
issued before the ^D3 command. The only difference between this command
and the ^D73 is the ability to increment and/or decrement sequential numbers
in a batch.
XXX 76 Load Delay Time Between Printed Labels: Delays the printing between
labels in a batch. The “^Axxx” specifies the delay time in tenths of a second
with a maximum value of 650. For example, “^A10^D76<CR>” would
introduce a one second delay between printed labels. This command is
typically used in conjunction with the Peel-n-Dispense mode and applicators.
5.13.2 Auto-sizing and Valid GAP Commands
The auto-size command attempts to automatically calculate important format values for the
label header including LSY, GAP, AGD, SPG, the ^D90 value, and the ^D91 value. The
printer feeds a sample of labels through the GAP sensors and takes an average of the
values it receives. The auto-size command uses the appropriate sensors to detect the
registration marks set by the ^D47 command. Before issuing the auto-size command, verify
that the ^D47 is set to the proper setting for the media being used.
5-30 224/424 Operator’s Manual - 880027-1000
Chapter 5 Printer Commands
When using media that contains a black line for the registration mark, first execute the
^A3^D47<CR> command sequence before issuing the auto-size command or the results
may be invalid.
^A ^D COMMAND
39 Auto-size:
0 Clears the use of auto-size values set by issuing the ^A1^D39<CR>.
1 Uses the values obtained for header variables instead of what is specified in
the format file’s header.
2 Automatically sizes the label and displays to the terminal screen the values for
the format header.
3 Same as ^A2^D39<CR>, but the values will be printed on the media.
5 Diagnostic Mode that steps the motor while displaying the readings from the
GAP detectors to determine the media’s proper ^D91 setting. This is also
referred to as “tick-tick” mode.
5.13.3 Serial Number Commands
The following commands, ^D80 through ^D89, are used for the serial number function
commands of the printer. The printer can increment or decrement any single serial number
on the label by any amount. If the format contains more than one serial number, then all
serial number fields can only increment or decrement by a value of one. Single and Multiple
serial number commands cannot be used on the same format. Please note that the ^D57
command clears most of the serial number commands. Therefore, all serial number
commands should be placed after the ^D56 command or just prior to the ^D3 command.
The following two commands are valid for both single and multiple serial number functions:
^A ^D COMMAND
80 Clears Commands 86, 88, 89.
81 Disable Serial Number Function: This command disables both single and
multiple serial number functions.
The next three commands deal with the single serial number functions:
^A ^D COMMAND
XX 84 Load Text String Number to Increment/Decrement: Instructs the printer
which text string number to increment or decrement. The ^Axx value
determines which of the text strings will be used for incrementing or
decrementing.
XX 85 Load Increment/Decrement Step Value: The single serial number functions
increment or decrement by this value. ^Axx is the amount of increment or
decrement.
224/424 Operator’s Manual - 880027-1000 5-31
Printer Commands Chapter 5
^A ^D COMMAND
XX 86 Single Serial Number Status:
0 Disable increment and decrement
1 Enable increment: The serial number will be incremented by the step value
specified by the ^D85 command.
2 Enable decrement: The serial number will be decremented by the step value
specified by the ^D85 command.
The next three commands determine the status of multiple serial numbers:
^A ^D COMMAND
XX 87 Load Field Number to Clear Increment/Decrement: This command is used
to clear the status of one or more fields that are using the serial number
increment/decrement function. Example: A “^A1^D87<CR>” instructs the
printer to clear the increment/decrement function of text string number 1 or the
first text string.
XX 88 Load Field Number to Increment by 1: The ^Axx specifies which field to
increment by one.
XX 89 Load Field Number to Decrement by 1: The ^Axx specifies which text string
field that will be decremented by one.
A sample format using the single serial number function:
^D57 <CR>
1,575,609,,25,35,0,1,285,0,0 <CR>
1,280,300,2,1,5 <CR>
^D56 <CR>
^A2^D86 <CR>
^A1^D84 <CR>
^A5^D85 <CR>
^A3^D75 <CR>
^D2 <CR>
20 <CR>
^D3 <CR>
This format would enable the decrement function (^A2^D86). Select text string #1 to
decrement (^A1^D84), load the step value of 5 (^A5^D85) and then print three serialized
labels (^A3^D75). The printed result would be “20” for the first label, “15” for the second
label, and “10” for the third or last label.
5-32 224/424 Operator’s Manual - 880027-1000
Chapter 5 Printer Commands
A sample format using the multiple serial number function:
^D57 <CR>
2,575,609,,25,35,0,1,285,0,0 <CR>
1,280,300,3,1,5 <CR>
2,280,100,3,1,5 <CR>
^D56 <CR>
^A1^D88 <CR>
^A2^D89 <CR>
^A3^D75 <CR>
^D2 <CR>
100 <CR>
200 <CR>
^D3 <CR>
This format would enable the multiple serial number function and select the first text string to
increment by one (^A1^D88), the second field to decrement by one (^A2^D89), and print
three serialized labels (^A3^D75). The first text string would be printed as “100”, “101”, and
“102” while the second text string is printed as “200”, “199”, and then finally “198”.
5.14 Label Header Parameter Override Commands
It is possible to override label header parameters by adding one or more of the following
commands after the label format.
^A ^D COMMAND
40 Clears Commands 41 through 51
XX 41 Load Number of Fields in Layout (HFM): The ^Axx specifies the value.
XX 42 Load Label Width in dots (LXS): The ^Axx specifies the value.
XX 43 Load Label Height in dots (LSY): The ^Axx specifies the value.
XX 44 Load the Web Size in dots (WEB): The ^Axx specifies the value.
XX 45 Load the Gap Size in dots (GAP): The ^Axx specifies the value.
XX 46 Load Print Speed: The ^Axx specifies the value.
XX 47 Load the Label Control Byte (LCB): The ^Axx specifies the value.
XX 48 Load the Number of Steps to Activate Gap Detector (AGD): The ^Axx
specifies the value in Dot Rows.
XX 49 Load the Number of Steps Past Gap (SPG): The ^Axx specifies the value
in Dot Rows.
XX 50 Load X Direction Offset (OFX): The ^Axx specifies the value.
224/424 Operator’s Manual - 880027-1000 5-33
Printer Commands Chapter 5
^A ^D COMMAND
XX 51 Load Y Direction Offset (OFY): The ^Axx specifies the value.
5.15 Text String Commands
These commands offer special functions pertaining to the text strings. Some of the special
functions would include Pre-padded text and auto-print.
^D COMMAND
^A
60 Clears Command ^D61
XX 61 Mark Text Starting Position: The ^Axx specifies which text field to start
entering new data. This is useful for creating variable text fields after a string
of fixed text fields. If set to a value of 2, the first line of new text entered
following the ^D2 will overwrite line two. If two new text strings are entered,
the existing text lines two and three will be overwritten. This command is used
when fixed data is used much like a template and only the variable data is to
change.
62 Pre-padded Text: This command is used to pre-pad text data. Any data
already loaded into a field will be retained if the ^D62 command is sent.
The following is an example of Pre=padded text:
^D57<CR>
3,575,609,,25,35,0,1,285,0,0 <CR>
1,300,500,7,1,5<CR>

B<CR>
C<CR>
^D62<CR>
^D2<CR>
line 1<CR>
line 2<CR>

This format would produce a label with “Aline 1”, “Bline2”, and “Cline 3” printed
on the label.
5-34 224/424 Operator’s Manual - 880027-1000
Chapter 5 Printer Commands
^A ^D COMMAND
X 63 Text Control Mode: Allows the entry of new text without the ^D2 command
and/or clears all previous text when new text is added.
0 Disable modes 1 and 2.
1 Enable Auto-Print mode. If this mode is selected, the printer will accept new
text strings without requiring the ^D2 command. The printer can also autoprint a label when the number of received text strings (carriage returns) equal
the number specified by the ^D64 command. This mode is useful when
interfacing to a scale, bar code wand of other limited host that is capable of
generating and sending carriage return characters.
2 Clear Previous Text Upon Receiving New Data. When one of more characters
of new text is entered, the all-existing text data will be erased. The printer may
be programmed to enter the mode automatically upon power-up by position 1
of software switch #2 (^D22 command).
3 Enable modes 1 and 2.
XX 64 Auto-Print String Count: This command is used in conjunction with the
^A1^D63 auto-print command. The ^Axx specifies the number of text strings
(carriage returns) to accept before issuing the print command. When the
printer is in the auto-print mode, it is not necessary to send the ^D2 command
to enter text or the ^D3 command to initiate printing. The printer will accept
incoming text strings and print the label as soon as the number of strings
equal the amount specified by the ^D64 command.
The following is an example of the ^D61, ^D63, and ^D64 commands:
^A0^D64<CR> (Clears any old settings)

Printer Commands Chapter 5
5.16 Memory Commands
These commands offer special functions related to clearing, storing, and processing data in
the RAM and FLASH memory.
The printer can store up to 128 FORMAT files into the printer’s RAM memory and another
128 files into FLASH memory. Once stored, these files can be loaded from memory rather
than having to be sent down thru the serial port. Formats are retained even after power has
been cycled when stored in FLASH memory. Formats stored in RAM will be lost when the
printer is turned “OFF.”
The printer can be configured through software switch #2 (^D22 command) to automatically
process a specific format from the FLASH memory when the printer is turned “ON.” The
printer treats the stored formats as if they were sent through the serial port.
^A ^D COMMAND
XX 54 Send Format from RAM to Serial Port: The ^Axx specifies the slot number
(1-128) where the format file is stored in RAM.
XX 58 Process Format Saved in RAM: The ^Axx selects which stored format to
process (1-128).
XX 59 Save Formats to RAM. (volatile)
The ^Axx selects the memory slot (1- 128) into which the format is to be
saved. A format file must be terminated by an ESC (HEX 1B) or “[“ (left
bracket) character to save the format.
Sample format saved to RAM slot #1: ^A1^D59

^A ^D COMMAND
XX 131 Delete a FORMAT from FLASH.
^A0 deletes all FORMAT files in FLASH ^Axx deletes the FORMAT file stored
in FLASH slot (1 – 128).
This command deletes the Label FORMAT stored in Slot #xx of the FORMAT
storage bank in FLASH memory. Use this command to clear a FORMAT slot
in FLASH before storing a new FORMAT into the slot.
XX 134 Delete a GRAPHIC from FLASH.
^A0 deletes all GRAPHIC files in FLASH
^Axx deletes the GRAPHIC stored in FLASH Slot #xx
Valid values for Axx are A1 ⇒ A255. The user selects the CGN #xx that will
be cleared.
: After the GRAPHIC file has been deleted, the ^D119 command may be used
Hint
to verify that Slot #xx is now available in FLASH. The GRAPHIC may extend
over several slots and the ^D119 will indicate how many slots are used by the
GRAPHIC.
xxyy 135 Save FONTS to FLASH. (See Chapter 7)
This command is not normally seen by the user. It is put into a FONT file by
the FONT converter program which generates a special ^Axxyy^D135 code
which is placed at the beginning of the FONT download file. The ^Axxyy tells
the printer the overall size of the file according to this format:
xx = the number of additional 64KB sectors in the FONT file set
yy = CGN # (1-255)
If xx = 00, then the FONT fits into one 64Kbyte sector of memory and there
are no additional sectors required for the FONT.
5-38 224/424 Operator’s Manual - 880027-1000
Chapter 5 Printer Commands
If xx > 00, then the FONT is larger than one 64KB sector, and xx is the
number of ADDITIONAL 64KB sectors needed for the FONT. The xx field >
00 signals the printer to get ready for a multi-sector FONT download. Each
subsequent download contains a header with the xx field decremented by 1.
The last download file has a header field xx = 00.
EXAMPLE: ^A0124^D135 This command tells the printer that an extended
FONT download for FLASH memory is coming. The download will be 2
sectors long, and the printer will access the FONT in FLASH memory using
CGN #24 and TCI #7. The ^A0124^D135 command will be right at the
beginning of the file. So the ^D135 command is never sent by itself, it’s
always in a FONT download file, and the user never really sees it.
The FONT download file may be larger than 64Kbyte. The only limit on the file
size is the amount of memory available to hold the file. When the FONT file is
created, a specific reference number, called a CGN # is assigned to the file by
the user. After the FONT file has been downloaded and stored in FLASH, the
printer retrieves the FONT from FLASH by using its CGN # and TCI #7(for
FLASH). The FONT may be stored anywhere in the printer’s FLASH memory;
it is NOT restricted to a specific FLASH memory location. The printer
maintains a address table that tells where each FONT CGN # is stored in
FLASH.
The CGN # is established by the user when the FONT download file is created
using the font converter program. Since this is an arbitrary number picked by
the user, it is possible to create two separate FONT files with the same CGN
#. In fact, many FONT files could be created using the same CGN #. For the
printer to function properly, each FONT in FLASH must have a unique CGN #.
If a FONT is downloaded that has the same CGN # as a FONT that is already
stored in FLASH, then an error message is sent back indicating a Duplicate
CGN error.
The printer’s FLASH is nonvolatile, so FONTS that are downloaded using the
^D135 will be stored in FLASH memory until specifically erased by the user.
The following 3 parameters are included in the FONT file when it is created:
1. Memory destination: RAM or FLASH
2. Memory File #: 1Æ255 (this is the CGN #)
3. Rotation: 0°, 90°, 180°, or 270°
How to save a FONT to FLASH:
1. Create the special FONT download file with FLASH set as the memory
destination,
2. Send the file to the printer using a standard communications program
set for 8 data bits, no parity, 1 stop bit.
: After the FONT file has been sent, the ^D119 command may be used to verify
Hint
that the new FONT is now available in FLASH.

^A ^D COMMAND
XX 136 Delete a FONT from RAM.
^A0 deletes all FONTS from RAM
^Axx deletes the FONT stored in RAM Slot #xx
Valid values for Axx are A1 ⇒ A255. The user selects the RAM memory Slot
#xx that will be cleared.
Hint: After the FONT file has been deleted, the ^D119 command may be used to
verify that Slot #xx is now available in RAM. The FONT may extend over
several slots and the ^D119 will indicate how many slots are used.
XX 137 Delete a FONT from FLASH.
^A0 deletes all FONTS from FLASH
^Ax deletes the FONT stored in FLASH Slot #x
Valid values for Axx are A1 ⇒ A255. The user selects the FLASH memory
Slot #xx that will be cleared.
Hint: After the FONT file has been deleted, the ^D119 command may be used to
verify that Slot #xx is now available in FLASH. The FONT may extend over
several slots and the ^D119 will indicate how many slots are used.
XX 138 Process a FLASH FORMAT.
^Axx references the FORMAT file stored in slot #xx.
Valid values for Axx are A1 ⇒ A128.
Label FORMATS are saved into FLASH Slots #1 thru #128. Each of these
FORMAT slots specifies how to build the dot rows that are used to print a label
on the 224 and 424 printers.
This command tells the printer to take the Label FORMAT file in Slot #xx and
build up its image in the printer’s slice buffer. After this command is finished,
the label may be printed by sending the ^C print command.
NOTE: If the FORMAT file contains a print command, then the label will be
printed at the end of this command.
XX 139 Send a FLASH FORMAT to the host.
^Axx references the FORMAT file stored in slot #xx.
Valid values for Axx are A1 ⇒ A128.
Label FORMATS are saved into FLASH Slots #1 thru #128. This command
causes the printer to send a previously loaded FORMAT file out the
communications port to the HOST.
Use this command to view label FORMATs that have been saved in the
printer’s non-volatile FLASH memory.

X 152 48-466 SPG Correction.
This command is nonvolatile and only used in conjunction with the 48-466
Emulation mode (^D26 command). It is used to adjust the SPG value to
compensate for the mechanical differences between the 48-466 and X24
printers. Each time the printer receives an SPG value; it will be decreased or
increased by the amount entered for ^Axx. If the XX value is less than 127
then; SPG = SPG - XX. If the XX value is greater than 127 then; SPG = SPG
+ XX - 127.
Example: If the value for XX was 33 and a format is sent to the printer with the
SPG set to 100, the resulting SPG would be 67 (SPG = 100 - 33).
Example: If the value for XX was 147 and a format is sent to the printer with
the SPG set to 90, the resulting SPG would be 110 (SPG = 90 + 147 - 127).

Chapter 6: Downloadable Graphics
The 224 and 424 printers allow the user to download their own GRAPHICS and store the
GRAPHICS in either non-volatile FLASH memory, or in volatile RAM memory.
6.1 FLASH Data Types
The printer’s FLASH memory provides non-volatile storage for several types of data:
1) 120 FLASH memory banks are 64Kbyte sectors for storing downloadable FONTS
and GRAPHICS.
2) 128 slots for label FORMATS.
3) 7 “embedded” FONTS. These FONTS are downloaded at the factory.
NOTE: The printer’s FLASH memory retains data after power is turned OFF. So data that
is downloaded to the printer’s FLASH memory will be available until erased by the user.
FONTS & GRAPHICS stored in FLASH memory are accessed using TCI #7 and the
appropriate slot # (CGN #).
6.2 RAM Data Types
The printer’s RAM memory provides volatile storage for several types of downloadable data:
1) RAM memory slots #1 thru #255 are used to store downloadable FONTS and
GRAPHICS using TCI #8.
2) 128 slots for label FORMATS.
NOTE: The printer’s RAM memory is NOT battery backed-up. So when the printer is
turned OFF any data stored in the RAM memory is lost. The downloaded data that is stored
in RAM is temporary.
6.3 Using the BMP2MIC.exe GRAPHIC Conversion Utility
Bitmap graphic image files (*.bmp) may be converted to a LDS compatible format by using
the BMP2MIC.exe Graphic Conversion Utility. This and other conversion utilities may be
downloaded at http://www.microcomcorp.com.
The conversion utility is a DOS-base program and will require access to a DOS prompt.
Before starting the conversion utility, it would be helpful to gather the following information:
1)
In File This is the *.bmp file to be converted. (Limit the file name to 8
characters and locate file in the same directory as the conversion utility to simplify
data entry into the program.)
2) Out File Create a name for the converted GRAPHIC File. (Limit the file name
to 8 characters. An extension is not necessary.)

6.4 Graphic Download Methods
The printer supports both compressed and uncompressed graphic downloads. The
compressed format shortens the download time by reducing the number of bytes sent to the
printer. Please note that the compressed format is only usable on 8-bit data connections
and will NOT function on 7-bit data connections.
6.4.1 Uncompressed Graphic Downloads
The uncompressed converted GRAHIC file can be sent on either 7 or 8-bit connections, is
more flexible, and encodes using ASCII-HEX, but this method results in a much larger file
size than a compressed format.
The converted GRAPHIC file can be sent to the printer via any active printer port. A
terminal emulation program such as Hyper Terminal, ProComm, Tera Term, etc is
commonly used.
Note: It is highly recommended to use hardware flow control.
6.4.2 Compressed Binary GRAPHIC Downloads
The compressed format shortens the download time by reducing the number of bytes sent
to the printer. Data compression is accomplished by converting strings of 0 HEX or FF HEX
to shorter byte-plus-count sequences. These sequences are then expanded to the original
number of bytes inside the printer. A compressed binary converted GRAPHIC file must be
sent on a 8-bit data connection.
The printer must be setup to accept downloaded binary compressed files by setting
Software Switch #3, position 7 to “1”. Otherwise, the file may be sent to the printer through
any active printer port.
6.5 Advanced GRAPHIC Format Conversion for Programmers
The following sections are provided to developers who wish to create usable GRAPHIC
images within their own applications. Commands in the following section are not typically
seen for users using Microcom GRAPHIC utilities.

Downloadable Graphics Chapter 6
6.5.1 Save Compressed Graphics to RAM (D107)
The following is the format of the ^D107 command when used to store a compressed
GRAPHIC image file into RAM.
^A<RAM Memory Slot Number>^D107<CR>
<Rotation> <Count> <Image Data>
Where:
<RAM Memory Slot Number> is the memory slot location (1-255) where the GRAPHIC will
be saved in the printer’s RAM memory. The printer uses the same TCI of “8” to select
downloadable fonts or graphics. Therefore a font and a graphic cannot have the same Slot
Number or CGN number.
<Rotation> is an 8-bit integer, 0 for an upright GRAPHIC and 1 for a GRAPHIC rotated 90degrees counter-clockwise.
<Count> is a 32-bit integer, least significant byte first. This is the number of uncompressed
bytes that the GRAPHIC image uses, not the number of bytes that will actually be
transmitted. Due to compression, the number of bytes transmitted will normally be less than
this number.
<Image Data> is the compressed binary image.
6.5.2 Save Compressed Graphics to FLASH (D133)
The following is the format of the ^D133 command when used to store a compressed
GRAPHIC image file into FLASH.
^A<FLASH Memory Slot Number>^D133<CR>
<Rotation> <Count> <Image Data>
Where:
<FLASH Memory Slot Number> is the memory slot location (1-120) where the GRAPHIC
will be saved in the printer’s FLASH memory. The printer uses the same TCI of “7” to select
downloadable fonts or graphics. Therefore a font and a graphic cannot have the same Slot
Number or CGN number.
<Rotation> is an 8-bit integer, 0 for an upright GRAPHIC and 1 for a GRAPHIC rotated 90degrees counter-clockwise.
<Count> is a 32-bit integer, least significant byte first. This is the number of uncompressed
bytes that the GRAPHIC uses, not the number of bytes that will actually be transmitted.
Due to compression, the number of bytes transmitted will normally be less than this number.
<Image Data> is the compressed binary image.

Chapter 6 Downloadable Graphics
6.5.3 Binary Compression Algorithm
The binary data that make up the image file is a run-length compressed version of the
image data described in Section 7.2. Bytes with a value of “0” HEX or “FF” HEX are
followed by another byte indicating the number of times that value is repeated.
For example: Suppose the original (uncompressed) image file has a sequence of bytes like:
(All values are listed in Hexadecimal)
“00 01 02 03 04 00 00 00 00 00 00 FF FD FF FF FF FF FF 00 FF”
The encoded result would like this:
“00 00 01 02 03 04 00 05 FF 00 FD FF 04 00 00 FF 00”
Result interpretation:
00 - the first byte is 00
00 - count of 0 (the previous 00 byte is not repeated or repeated zero times)
01 - a 01 byte
02 - a 02 byte
03 - a 03 byte
04 - a 04 byte
00 - another “00” byte in the file
05 - the “00” byte is repeated 5 times for a total of 6 “00” bytes (00+05=6 “00” bytes)
FF - a “FF” byte
00 - count of 0 (the previous “FF” byte is not repeated or repeated zero times)
FD - a FD byte
FF - another FF byte
04 - the FF byte is repeated 4 times for a total of 5 “FF” bytes (FF+04 = 5 “FF” bytes)
00 - another 00 byte
00 - repeat count = 0
FF - another FF byte
00 - repeat count = 0
The compression scheme is slightly inefficient for single 00 HEX and FF HEX occurrences
by entering two for each of these occurrences but most image bitmaps include large areas
of either blank space (00 HEX) or black space (FF HEX).
If a string of more than 255 “00” HEX or “FF” HEX occurs, the byte-plus-count sequence
may be repeated as often as necessary to incorporate all occurrences of the byte. For
example, a string of 1132 “FF” HEX bytes in sequence may be encoded as:
“FF FF FF FF FF FF FF FF FF 6B”
The first four pairs of “FF” HEX each encode 256 bytes of “FF” HEX (one for the first “FF”
byte and 255 copies) totaling 1024 bytes of “FF” HEX. The next “FF” HEX byte adds
another and the 6B HEX adds 107 additional copies for a total of 1132 FF HEX bytes.
(4 X 256)+1+107 = 1132

6.5.4 Uncompressed FONT to RAM (^D104)
This command allows graphic and/or font images (fonts must be less than 64KB
uncompressed) to be transmitted in ASCII-HEX, thereby allowing all data to pass over 7 or
8-bit data connections. This command is usable on data connections that support either 7
or 8-bit data.
The following is the format of the ^D104 command when used for a graphic image file:
^A<Slot Number>^D104<CR>
<Rotation> <Count> <Image Data>
Where:
<Memory Slot Number> is the memory slot location (1-255) where the graphic will be saved
in the printer’s memory. The printer uses the same TCI of “8” to select downloadable fonts
or graphics. Therefore a font and a graphic cannot have the same Slot Number or CGN
number.
<Rotation> is an 8-bit integer, 0 for an upright font, and 1 for a 90-degree rotated image.
<Count> is a 32-bit integer, least significant byte first. This is the number of bytes that the
image uses.
<Image Data> is the graphic image data that has been converted to ASCII-HEX.
ASCII-HEX Conversion
The ASCII-HEX conversion is performed by “ORing” the most significant and least
significant nibbles of every byte with “30” HEX.
For Example: To convert the byte “6C” to ASCII-HEX, simply OR the first and second
nibbles with “30” HEX. This results in the two bytes “36” HEX and “3C” HEX. This
conversion results in a file size that is twice as big as the source, the data can now be
transmitted over a 7-bit data connection.

6.6 Graphic Image Data Format
The image data consists of a set of data structures and location offsets to those structures.
All data is stored in binary form. Multi-byte values are stored least-significant-byte first.
The method illustrated below allows graphic images to span 64KB memory segments.
When using graphics over 64KB, the printer will determine the number of 64KB slots
required to store the entire graphic and will split the large file into the correct number of
smaller files internally. The printer stores these smaller files sequentially in the slots
following the one specified in the appropriate load or save graphic command. Therefore,
before sending a graphic file that is 64KB or more (uncompressed size), make sure that the
specified font slot has enough following empty slots to store the file properly.
Graphics that are stored in multiple slots in this way may still be printed as if they are one
large graphic. In the label format, refer to the first slot (the one specified in the download
command) regardless of how many slots that may be required for large graphics. The
printer will automatically append the additional graphic files seamlessly without additional
user intervention.
(Word is a 16-bit value, Byte is an 8-bit value, and Label is a location within the file)
Label start: the beginning of the file
Word, Word, lookup_table_offset distance in bytes from start to beginning of

Label lookup_table beginning of lookup table
Word char_offset [last_char-first_char] an array of offsets, one for each character in
font. Each offset is the distance, in bytes, from
the start to the beginning of the corresponding
character’s data structure. The first word in this
array is the offset to the first character’s data;
the last word is the offset to the last character’s
data.

Chapter 7: Downloadable Fonts
The 224 and 424 printers allow the user to download their own fonts and store the fonts in
either volatile RAM memory, or non-volatile FLASH memory.
7.1 FLASH Data Types
The printer’s FLASH memory provides non-volatile storage for several types of data:
1) 120 FLASH memory banks are 64Kbyte sectors for storing downloadable FONTS
and GRAPHICS, using TCI #7.
These FONTS are downloaded using the ^D135 command. These
GRAPHICS are downloaded using the ^D133 command.
2) 128 slots for label FORMATS.
These FORMATS are downloaded using the ^D130 command.
3) 7 “embedded” FONTS. These FONTS are downloaded at the factory.
NOTE: The printer’s FLASH memory retains data after power is turned OFF. So data that
is downloaded to the printer’s FLASH memory will be available until erased by the user.
FONTS & GRAPHICS stored in FLASH memory are accessed using TCI #7 and the
appropriate slot # (CGN #).
7.2 RAM Data Types
The printer’s RAM memory provides volatile storage for several types of downloadable data:
1) RAM memory slots #1 thru #255 are used to store downloadable FONTS and
GRAPHICS using TCI #8.
These FONTS are downloaded using the ^D127 command.
These GRAPHICS are downloaded using the ^D107 command.
2) 128 slots for label FORMATS.
These FORMATS are downloaded using the ^D59 command.
NOTE: The printer’s RAM memory is NOT battery backed-up. So when the printer is
turned OFF any data stored in the RAM memory is lost. The downloaded data that is stored
in RAM is temporary.
7.3 Using the Font Conversion Utilities
The printer treats downloadable fonts just like the standard bitmapped font mentioned in
Chapter 5. Both LaserJet™ and TrueType® fonts can be converted using the
“SFP2MIC.exe” or “TTF2MIC.exe” software utilities. Note: The “SFP2MIC.exe” program
uses the Portrait or 0 degree source rotation for both normal and rotated fonts.
Downloadable font fields use the same structure as the bit mapped fields with the only
difference being that the TCI must be set to an “8” for volatile downloadable fonts and the
CGN refers to the memory slot location of the downloaded font. Nonvolatile fonts are
accessed thru TCI “7”.

Downloadable Fonts Chapter 7
The following section details the process required to convert and download fonts to the
printer. The conversion utilities “SFP2MIC.exe” and “TTF2MIC.exe” may be downloaded at
http://www.microcomcorp.com. These 16 bit DOS utilities convert LaserJet™ SFP or
TrueType® TTF fonts into a format that is suitable for downloading to the printer.
7.3.1 SFP2MIC.exe Program
1. Run the SFP2MIC program from a DOS prompt.
2. Follow the on screen instructions and note the slot number where the image is saved.
The 224 and 424 printers use the same font structure as the Model 412 printer.
Select the Model 412 printer when converting fonts for the 224 and 424 printers.
3. Make sure the destination memory slot is clear. The ^D100 command can be used
to clear the printer’s memory.
4. Download the resulting file (filename N12 (normal rotation) or R12 (rotated)) file to
the printer.
7.3.2 TTF2MIC.exe Program
1. Run the TTF2MIC program from a DOS prompt.
2. Follow the on-screen instructions and note the slot number where the image is
saved. The 224 and 424 printers use the same font structure as the Model 412
printer. Select the Model 412 printer when converting fonts for the 224 and 424
printers.
3. Make sure the destination memory slot is clear. The ^D100 command can be used
to clear the printer’s memory.
4. Download the resulting file (filename N12 (normal rotation) or R12 (rotated)) file to
the printer.
7.4 Font Download Methods
The printer supports both compressed and uncompressed graphic and font downloads. The
compressed format shortens the download time by reducing the number of bytes sent to the
printer. Please note that the compressed format is only usable on 8-bit data connections
and will not function on 7-bit data connections. The uncompressed (^D104) is usable on
either 7 or 8-bit connections and is more flexible but encodes using ASCII-HEX. This
results in a much larger file size. Microcom Corporation recommends the use of the
compressed format when possible.
7.4.1 Compressed Binary Commands
These commands allow graphic images or fonts to be transmitted in binary, thereby
reducing the number of bytes sent to the printer. Furthermore, the commands allow for data
compression by converting strings of 0 HEX or FF HEX to shorter byte-plus-count
sequences. These sequences are then expanded to the original number of bytes inside the
printer. These commands are only usable on data connections that support 8-bit data. So
the serial port MUST be configured for 8 Data Bits and no parity. These commands will
NOT function correctly with a serial port configured to 7-bit data bits.
