Verifying Printer Communications With Your System

After connecting the printer to your system, you need to test the
communications. The easiest way to test communications is to set the
printer to Data Line Print mode, which is part of Test and Service mode,
and send a character string down from your system.

If you have just printed a configuration test label, you are already in Data
Line Print mode. Start the following procedure with Step 4.

To verify communications with your system

1. Turn the On/Off switch to the off position.

2. Press and hold the Feed/Pause button while you turn the On/Off switch
to the on position. The printer prints the hardware configuration test
label.

3. Release the Feed/Pause button. You are now in Data Line Print mode.

4. Transmit at least four characters from your system.

1-22

At this point the printer does not attempt to interpret any printer
commands, but simply prints each character with its hexadecimal
equivalent underneath.

An example of using DOS to verify printer communications follows this

Note:

procedure.

5. To enter normal Print mode, turn the printer power off and then on
again.

If this procedure does not work, make sure that the DIP switches match the
serial port configuration of the system. Also, make sure you have the printer
cable securely plugged into the correct port of your system.

If you receive a write fault error, your cabling may not be correct. See
“Connecting the Printer to Your System” earlier in this chapter for more
information.

FranklinGothic

1233*

Example of Using DOS to Verify Printer Communications

1. At the DOS prompt, type this command and press Enter:

MODE COM1 96,E,7,1,N

The command configures the serial port.

2. Type these command lines and press Enter:

COPY CON COM1
ABCDEF^Z

where:
COPY CON COM1 tells the PC to copy the following information to the

COM1 port.

ABCDEF are random characters entered at the host.
^Z (Ctrl-Z) Enter sends the information to the printer.

The printer prints these characters:

Loading Media Into the Printer

You can load media into the 3440 printer in three different ways:

• fanfold media printing (covered in Chapter 1)

• roll media for straight-through printing

• roll media for self-strip printing

You can load media with the printer power turned on or off. The following
procedures for loading media assume that you have set the On/Off switch
to the on position.

Loading Roll Media for Straight-Through Printing

In straight-through printing, you load a roll of media on the supply roll post
and feed it straight through the printer mechanism and out the front of the
printer. As the 3440 prints individual labels, you can remove them from the
roll by pulling them down across the tear bar.

FranklinGothic

Helv Condensed

FG 8pt Italic

2-6

Note: This procedure covers how to load media for straight-through print mode
using a roll of direct thermal or thermal transfer label media. The default setting for
the printer is direct thermal mode.

Note: You should find a small label with a three-digit sensitivity number printed
on it attached to your roll of media or a 15 digit number stamped on the side of the
media roll. Save this information. You will need it to set the correct media
sensitivity number. See “Setting the Media Sensitivity Number” later in this
chapter for help.

To load the media

1. Raise the printhead by rotating the head lift lever clockwise until the
printhead disengages.

2. Turn the supply roll retainer counterclockwise to release it and then slide
it to the outer end of the supply roll post. Turn it clockwise to lock it in
place.

Note: If you are replacing the empty media roll with a new roll of the same
width, you do not need to adjust the edge guide or the supply roll retainer.

1233*

3. Place the media roll on the supply roll post and position it firmly against
the printer.

Note: If you are using a narrow roll of media (less than 3 inches), insert the
media support between the roll of media and the supply roll retainer before
securing it.

4. Turn the supply roll retainer counterclockwise and slide it up to the edge
of the media roll. Turn the supply roll retainer clockwise to secure.

5. Unscrew the edge guide and slide it all the way to the outer edge of the
lower media guide. Screw it in place.

Loading Media for Self-Strip Printing

Use self-strip printing in applications where you want to apply labels to a
surface immediately. After printing a label, the printer prints out the label
with the backing removed. The rewinder hub collects the backing after it
passes over the self-strip assist roller. The rewinder hub can hold the
backing from an entire roll of media.

Note: You should find a small label with a three-digit sensitivity number printed
on it attached to your roll of media or a 15 digit number stamped on the side of the
media roll. Save this information. You will need it to set the correct media
sensitivity number. See “Setting the Media Sensitivity Number” later in this
chapter for help.

Setting the Media Sensitivity Number

Media sensitivity is important because you use it to optimize print quality
and print speed. The three-digit sensitivity number specifies the amount of
heat required by the printhead to image a label. The amount of heat that
each roll of media or ribbon requires is unique due to different chemistries
and manufacturing processes.

Intermec has developed heating schedules (the amount of heat required to
image a label) to produce the highest possible print quality for Intermec
media and ribbon combinations on Intermec printers. Look for the three
digit media sensitivity number on:

• the side of the media roll. Use the last three digits (140 in the example) of

the 15 digit number stamped on the roll for the media sensitivity
number.

• a small label attached to the roll of media.

• a small label attached to the plastic bag of your ribbon roll.

Communicating With the Printer

You are now ready to print labels by downloading data from the host to the
3440 printer. Downloading is the universal term used to describe the transfer
of information from the host to any connected peripheral device, such as the
3440 printer. When you transfer data from your printer to the host, you are
performing a process called uploading.

You can use several methods to download information in your data
collection system. The next sections describe different ways to communicate
with the printer.

Using the PrintSet Software

Use the PrintSet application software to easily configure your printer from
your PC. You can upload the current configuration settings, modify them,
and then download them to the 3440 printer. PrintSet also lets you:

• download graphics and fonts (including TrueType).

• print test labels.

2

• allocate memory.

• download configuration files.

For help using PrintSet, refer to the online help portion of the application
software.

Using Third-Party Software

You can use third-party software to set many of the printer parameters. You
can configure the parameters that your software does not set by using the
printer command set or the configuration DIP switches.

Use your third-party software to create label formats and convert graphics
into a user-defined character (UDC) format that the 3440 printer can
interpret. Refer to your third-party documentation and Chapter 5,
“Designing Labels and Using IPL Commands,” for more information.

2-19

3440 Bar Code Label Printer User’s Manual

Using Intermec Printer Language (IPL) Commands

You can create labels by downloading formats (designs) and data with IPL
commands. You can use the printer to perform any function or activate any
feature of the 3440 printer except for those features or functions that you set
with the DIP switches. Use the following methods to download commands
to the printer.

Note: For help using IPL commands, see Chapter 6, “IPL Commands.”

Downloading Printer Commands Using DOS

Use the DOS Copy command to download printer parameter command
strings or to print files stored on the PC. If necessary, you can modify and
download them several times. For example, if your first attempt at a label
format does not work, you can return to the text editor, change the incorrect
commands, and then download the format again. By using this method, you
eliminate the need to retype command strings that do not change.

Using ASCII Control Characters or Hexadecimal Equivalents

With many communications or terminal emulation software, you create the
commands by using the equivalent ASCII control characters. For example,
you enter <ETX> as Ctrl-C.

When you enter ASCII decimal equivalents in a word processor, they
display on the screen as special characters. For hexadecimal equivalent
(<ETX> = 03), consult the pull-out ASCII chart in Appendix A, “Printer
Reference.”

Using Readable Protocol/Command Characters

If it is difficult for you to edit or transmit command files containing control
characters, you may want to use the readable protocol/command characters
feature. To use the readable characters feature, type the ASCII characters in
as a string. Use angle brackets around ASCII strings to represent the ASCII
characters. For example, if you want to enter the ASCII mnemonic for “start
of text,” type the control character out as a readable character string: <STX>.

The printer automatically detects whether you are using control characters
or readable protocol/command characters by the start of text (<STX>)
character. Refer to the pull-out ASCII chart in Appendix A, “Printer
Reference,” for a complete listing of the control characters and their
readable protocol/command character equivalents.

All characters in a message must be in the same form as the start of text
(<STX>) character. For example, if you include control characters in a
message that begins with the readable protocol/command character <STX>,
the printer throws them away. Using readable characters may consume
more space and time, but it has the distinct advantage of displaying
everything on the screen in readable characters.

Downloading Printer Commands Using a Command String

Another way to download commands to your printer is through a PC
communications program, a terminal emulation program, or a host
terminal. If you make an error while entering commands, you must retype
the command string instead of just editing it. If you keep your command
strings short, it is easier to retype a command. Design your formats as
combinations of several short command strings rather than one very long
string.

2-21

3440 Bar Code Label Printer User’s Manual

Switching Between Print Mode and Program Mode

Print mode and Program mode are two different operating modes of the
3440 printer. Before you download information to the printer, make sure
that you are in the correct mode.

• Use Program mode to define formats, pages, fonts, and characters.

• Use Print mode to download data and print labels.

To enter Program mode

• Type this command:

<STX><ESC>P<ETX>

It is a good practice to send this command every time that you download
formats, even if you think the printer is already in Program mode. If the
printer is in Program mode, it ignores this command.

If you are operating your 3440 printer from a platform not discussed in this
manual, it is important to keep several things in mind:

• The 3440 is an ASCII printer.

• You must configure the 3440 printer to match the settings of your

platform to ensure proper communications.

• You must download data correctly structured for the commands. Refer
to Chapter 6, “IPL Commands,” for a complete listing of 3440 printer
commands.

• Ensure that the cable you are using to communicate with the printer has
the correct pin-outs. See “Connecting the Printer to Your System” in

Cleaning the Media Guides and Media Path

You should clean the media guides and media path regularly to keep debris
off the media surface and printhead where irregularities can spoil print
quality or damage the printhead. Cleaning the guides also prevents the
media from skewing or improperly tracking as it travels through the media
path, which can result in smeared images and print off the side of the label.
Always clean the media guides immediately after a label jam in the printer.

To clean the media guides and media path

1. Turn the On/Off switch to the off position and remove the power cord.

2. Remove the media cover.

3. Remove the media and ribbon (if necessary).

This chapter provides some hints for troubleshooting error messages that the
printer sends to the host and problems you may experience with the printer.

FranklinGothic

Troubleshooting Checklist

Even though Intermec designed the 3440 printer to operate under harsh
conditions, you may still encounter error messages at some time. You can
easily fix most of the errors you encounter and consequently not delay
operation of the printer for very long.

If you receive an error message or encounter a functional problem with the
printer, try the following:

1. Send a <BEL> command to the printer and see if the printer sends an
error message to the host in response.

2. If there is an error message, find it in the table under “Error Codes” in
this chapter. Follow the instructions after the error message to correct the
problem.

Preventing Data Loss

Several problems can cause data loss or communications problems on the
3440 printer. Data loss can result in printing errors or missing field data.

The 3440 printer is a serial ASCII device. It communicates with the host
through an ASCII serial communications I/O port. Hardware handshaking
involves the use of a hardware wire. Software handshaking involves a
two-way datalink between the devices. The two devices communicate with
each other without losing data through the use of handshaking. The printer
sends both forms of handshaking simultaneously when the printer’s input
buffer is full. Any loss of data can cause printing errors or missing data.

Hardware handshaking uses pins 11 or 20 of the RS-232 interface to control
data flow. When the printer is using Intermec Standard protocol, it holds
pins 11 and 20 high when it is ready to receive data. The printer holds the
pins low when it is in one of the following conditions:

• Buffer full

• Ribbon fault

FranklinGothic

Helv Condensed Troubleshooting

4

• No label stock

• Label at strip pin

The 3440 printer uses XON/XOFF protocol for software handshaking. When
the input buffer is full, the printer transmits an XOFF character. This
character alerts the host to the fact that the printer buffer is full and cannot
receive any more data. When the printer is ready to receive more data, it
sends the XON character.

To check for communications problems

1. Check the cabling from the printer to the host system.

2. Check the communications interfacing of the devices connected to the
printer.

3. Check the printer for proper electrical operation of the I/O port.

4. Ensure the host system is not overrunning the printer input buffers.

5. Ensure the data string being sent to the printer contains the correct
information.

4-9

3440 Bar Code Label Printer User’s Manual

Error Handling

This section describes how the 3440 printer handles certain error conditions
it may encounter in printer or programming commands.

Syntax Errors

The 3440 printer responds to syntax errors in the messages it receives from
the host by attempting to execute the commands. It does not ignore a
command with a syntax error. Instead, the printer produces output, even if
it is erroneous, which gives you an indication of what went wrong and what
you should do to correct the problem.

Parameter Errors

Certain commands require parameters. If you do not supply these
parameters, the printer substitutes default values. If a parameter is above its
maximum range limit, the printer uses the maximum value. If it falls below
the minimum range, the printer uses the minimum value. Refer to Chapter
6, “IPL Commands,” for the range and default value for each command.

1233*

FranklinGothic

Helv Condensed

Image Overrun Errors

Image overrun occurs when a label is too complex to image for a given print
speed. An overrun will cause the printer to abort the label being printed.
This error is most common on labels over 5 inches long.

The printer automatically attempts to correct for this error condition by
resetting to the lowest print speed and to the highest number of image
bands, and then repeats printing the label. The printer remains at this
setting until you reset it. If an image overrun still occurs, printing for that
batch of labels stops and the printer executes any following commands.

Installing one of the optional single in-line memory modules (SIMM) of 4 or
8 MB decreases image overrun errors.

4-10

1233*

FranklinGothic

Helv Condensed Troubleshooting

4

Invalid Numeric Character Errors

If you include non-numeric characters within a numeric data string of a
command, the printer disregards them and continues to process the rest of
the valid numeric characters. However, if a non-numeric character begins
the numeric data string, the printer uses a default value for the affected
command.

Here are two examples of valid numeric character strings and one example
of an invalid string:

12a valid
1a2 valid
a12 invalid

Insufficient Storage RAM Errors

Before storing new formats, graphics, or user-defined fonts in the static
RAM, the printer checks to see if it has sufficient memory to store them. If
there is insufficient memory, the printer disregards the last editing session.
The printer design preserves the integrity of the existing data in the static
random access memory (RAM).

Error Codes

Most of the problems you may encounter cause the 3440 printer to send an
error code to the host. When this happens, find the error code in the
following table and complete the instructions to correct the problem.

Replacing an 86XX or 3400 Printer

The 3440 printer provides compatibility with the 3400 printer and the earlier
8636 and 8646 bar code printers. The 3440 printer operates in Advanced
mode or 86XX Emulation mode. The two modes have three operational
subset modes: Print mode (contains configuration commands), Program
mode, and Test and Service mode.

Both Advanced mode and 86XX Emulation mode operate on the same basic
command set for print, configuration, program, and test and service
commands. On initial power up, the 3440 printer is in Advanced mode.
Advanced mode provides new features that make the 3440 compatible with
the 3400 printer. When you select 86XX Emulation mode, the 3440 printer is
compatible with the 8636 and 8646 printers. In 86XX Emulation mode, some
of the Advanced mode features are not available.

Differences Between 86XX Printers and Emulation
Mode

While the 3440 printer can emulate most functions of the 86XX series
printers, there are some features that are different or not implemented. This
section identifies those differences.

Helv Condensed

No BEL Status Response

The 86XX printer checks all incoming messages for errors before storing
them in the data buffer for later execution. When it receives an erroneous
message, it sends a BEL character back to the host as the printer status
response and discards the whole message. It continues to process the next
message without explaining to the host why it discards the previous
message.

The 3440 printer software does not ignore messages that have errors in any
of the commands. Instead, it executes all the commands as best as it can,
ignoring invalid commands and using printer defaults for erroneous
parameters. As a result, the printer treats mandatory data fields like
optional data fields. Attempting to execute all commands, in spite of errors,
gives the user clues about what went wrong and what they can do to
remedy the problem.

4-14

1233*

Even though the 3440 printer does not send the BEL status response back to
the host, it still generates the internal error code like the 86XX printer. The
user can use the same command to ask the printer to transmit its latest error
code to the host. The 86XX Emulation mode or Advanced mode setting does
not affect this feature of the 3440 printer.

FranklinGothic

Helv Condensed Troubleshooting

Prints Erroneous Labels

An 86XX printer does not print a label if the printed image does not fit
within the boundaries of the label stock. The 3440 printer prints the label,
even if the label is incomplete or the image overruns the next label. If the
printer overruns the next label, the printer form feeds to the following label
before the next print.

Limited User-Defined Protocol

The 3440 printer provides the capability to change protocol characters.
However, unlike the 86XX printer, you cannot define your own protocol.
You can substitute characters to use as protocol characters, but the rules for
the protocol chosen do not change. The printer does not use any protocol
character that you replace by the NUL character. One table of protocol
characters exists. You can redefine these characters and all protocols will
use them.

For example, you can redefine protocol characters by replacing control
characters with printable characters. Use caution since you cannot replace a
control character with more than one printable character.

formats increases from 10 to 99. Fields per format have increased from 100
to 200. The maximum data buffer size for a field increases from 50 to 200.
The number of UDCs increases from 10 to 100. The number of user-defined
fonts increases from 7 to 16.

Features Not Implemented

The 3440 printer does not implement some features of the 86XX printers.
These features include:

• Breach printing (eliminated on “speeded up 86XX printer”). You can
achieve the same functionality by defining the format, rotated 180
degrees, in a page.

• Printhead size command.

• 8100 protocol and command set.

• Mandatory data fields. The 3440 printer prints a label even if data is

missing from mandatory data fields.

• Prompting mode.

Differences Between the 3400 Printer and the 3440
Printer

Intermec derived the 3440 printer firmware from the 3400 printer firmware.
It uses the same commands and can receive command files and print
identical labels to the 3400 printer. While most features are similar, we had
to change or delete some features due to differences in the printer
electronics and mechanism.

Printhead Size

The 3400 printhead has 832 elements (dots) for a total of 4.16 inches. The
3440 printhead has 1792 elements for a total of 4.4 inches. The 3400 printers
have printhead elements (dots) that are 0.125 mm in size, for a total of 203
dots per inch (dpi). The 3440 printer has printhead elements 0.0625 mm in
size, for a total of 406 dpi.

When emulating a 3400 printer in 203 dpi mode, the 3440 printer doubles
the X and Y dimensions of bar codes, lines, boxes, and graphics to emulate
the larger dot size. The 3440 does not double the dimensions of human­readable characters. The resident fonts are the same size in both the 3440
and the 3400 printers. The only difference is that the characters print much
more clearly on the 3440 printer.

In the 3440 printer, all configuration measurements are in 5 mil units. All
label measurements, such as origin, are 2.5, 5, or 10 mil depending on the
dpi resolution in use.

Fonts

The 3400 printer comes with one outline font. Three Speedo outline fonts are
resident in the 3440 printer: two mono-spaced fonts and one proportional
font. All resident bitmap fonts are identical to the 3400 printer except that
characters are smoother on the 3440 printer due to the greater printhead
resolution. The software generates the characters for fonts 22 and 35
through 41 from the resident outline fonts, but the printer treats them as
bitmap fonts. The fonts now include Code Page 850 and you can access it as
a separate international language.
