CHAPTER 1

TERMS USED IN THIS MANUAL

This chapter describes the terms used in this manual.

 INPUT BUFFER AND LINE BUFFER

When the DPU-S245 (hereinafter it is referred to as “printer”) receives data (character codes and
commands) from the host devices, it stores the data in the printer input buffer . The input buffer has
a capacity of 4K bytes (4096 bytes). Then, the printer retrieves data from the input buffer. If data is
character code, data is stored into the line buffer. If data is command, data is executed as
command immediately.

The printer inputs character codes to the line buffer until the amount of character codes reaches
the amount to be printed on one line, then prints the characters. The printer repeats this operation
to print all the character data.

The relationship between the input buffer and line buffer is illustrated in Figure 1-1.

Line spacing is the space between the lines of printed characters (See Figure 1-2).

ABC

ABC

Line Spacing

Figure 1-2 Line Spacing

This printer use a line thermal print mechanism, therefore, a paper feed step is necessary before
printing characters or bit images.

The line feed command with printing feeds the paper for height of characters or bit images.
Therefore, a paper feed amount which is smaller than character or bit image height is ignored.
Printing with underline feeds the paper 4 dot lines in addition to the character height.
Line feeding without printing feeds the paper for specified line feed amount.

 Character Spacing

Character spacing is the space between each character in the horizontal direction (See Figure
1-3).

B

Character Spacing

Figure 1-3 Character Spacing

 Line

The word “line” in this manual indicates a line of characters. For example, the sentence “the printer
feeds paper one line” indicates that the printer feeds paper a line of characters.

 Dot Line

The words “dot line” in this manual indicate a line of dots in the vertical direction. For example, the
sentence “the printer feeds paper by one dot line” indicates that the printer feeds paper by the
space of 1 dot.

 Notation in the Technical Reference

 Hexadecimal

Hexadecimal is showing as follows;
Example: 0AH (a hexadecimal unit 'H' is added behind a hexadecimal number.)

2.4 PRECAUTIONS FOR USE

 Always print the two-dimensional bar code and ladder bar code (its bar is to be printed verticality to

the printer) within 0 to 40°C to ensure the bar code's reading accuracy.

 The two-dimensional bar code and ladder bar code printing always requires the low speed mode to

ensure its reading accuracy. Set the print speed to the low speed mode by using Motor Speed
Select (GS 'E') command.

 The height of the ladder bar code requires over 10 mm to ensure its reading accuracy.

Be aware, in particular, that reverse printing and ruled line tend to increase the ratio.
* Parts where many black dots are used when viewed in the direction vertical to the paper feed direction.

 Use of the battery pack at low temperature will run out of power in a shorter time.
 When printing ruled lines, a 2-dot configuration is needed. In case of a 1-dot configuration, the

printed lines may be invisible.

 Always use the printer within the shadowed range depicted in figure belo w Relationship between

Temperature and Humidity.

 When handling this product, be aware of static electricity. If the static electricity is discha rged, this

could case communication failure. When this problem occurs, disco nnect the USB connector that
is connected to the host device and wait few seconds before connect it again.

 When the printer is left unused for a long period of time, a white powder appears to the surface of

platen. (This is the powder by which an ingredient of a thermal paper was recrystallized.)
If the powder appears to the platen, wipe the platen with ethanol and use the printer after ethanol
has dried completely.
Also, make sure not to adhere ethanol except the platen area. If ethanol adheres except the platen
area, wipe it off immediately.

(NOTE) Refer to "SAFETY PRECAUTIONS" and "OPERAT ING PRECAUTIONS" on DPU-

S245 SERIES USER'S GUIDE which be included with the printer for other
precautions.

CHAPTER 3 INTERFACE

This chapter describes 4 types of the interface specifications which are required to connect the host device
with the printer.

Irrespective of the interface used, amount of the input buffer in the printer is 4k bytes, and transmission
buffer is 768 bytes. If the transmission buffer becomes the condition of the buffer full, the printer waits data
processing until the buffer can be received data. Be aware that printing process does not performed in that
meantime.

(5) Data reception

 Busy control

In Busy Control, RTS outputs MARK until the printer is ready to receive data after power ON.
After the printer is ready, RTS outputs SPACE and the received data is input to the input buffer.
When there are 33 bytes or less remaining in the input buffer, RTS outputs MARK. The host
device does not transmit data during RTS outputs MARK. When the input buf fer is ready to
receive data (there are 65 bytes or more in the input buffer) after stopping data reception, RTS
once again outputs SPACE. If an error occurs in the printer, RTS outputs MARK and inhibits data
entry until the error is cleared. If an error is cleared, RTS outputs SPACE again.
For RTS output when an error occurs, the setting is changed by Busy Output When Error Occurs at
function setting.

 Xon/Xoff control

In Xon/Xoff control, TXD outputs Xon code (11H) from power ON until the printer is ready to receive
data. Received data is input to the input buffer. When there are 65 bytes or less remaining in
the input buffer, TXD outputs Xoff code (13H). The host device does not transmit data while Xoff
code is received. When the input buffer is ready to receive data (there are 129 bytes or more in
the input buffer) after stopping data reception, TXD once again outputs Xon code. When this
control method is selected, the RTS signal always outputs SPACE. If an error occurs in the printer,
TXD outputs Xoff code and inhibits data entry until the error is cleared. When the error is cleared,
TXD outputs Xon code again.
For Xoff code transmission when an error occurs, the setting is changed by Busy Output When
Error Occurs at function setting.

 Data reception error in serial communication

When Parity is selected as Yes by the function setting, a '!' is printed next to data in which a parity
error occurred and a '?' is printed next to data in which any other error (framing error, etc.) occurred.
If a serial data reception error occurs, no error indication other than the printing of '!' and '?' is
performed (for example, the ERROR lamp does not light).

3-2

(6) Data transmission

 Busy control

In Busy Control, the conditions which transmit status information to the host device from the printer
are as follows;
When CTS Control of function setting sets to Enable, the printer sends data from TXD after
confirming CTS status as SPACE.
When CTS Control of function setting sets to Disable, the printer sends data from TXD regardless
of the condition of the host device.

 Xon/Xoff control

In Xon/Xoff control, the conditions which transmit status information to the host device from the
printer is that the printer sends data from TXD regardless of the condition of the host device.

(NOTE) Be aware that if the transmission buffer becomes full, the printer does not print

until the buffer is available.

(4) Data reception

USB data reception uses a bulk-out transfer method.
The data are received even during the printing operation, and when the data accumulate in the input
buffer by the amount of input buffer + 2 packets, the NAK response continues until amount of the input
buffer becomes 129 bytes or more.
The number of bytes that can be received with one packet is maximum 64 bytes. When an error
occurs, the NAK response continues until the error is cleared after receiving data of 2 packets.
For the operation when an error occurs, the setting is changed by Busy Output When Error Occurs at
function setting.

(5) Data transmission

USB data transmission uses a bulk-in transfer method.
The response data are stored temporarily in the transmission buffer, and a response is made to the
bulk-in packet request from the host device. If no transmission data exist, the zero length data is
returned when the bulk-in request is received. The number of bytes that can be transmitted with one
packet is maximum 64 bytes.

(NOTE) Be aware that if the transmission buffer becomes full, the printer does not print

until the buffer is available.

(7) Command response processing during IrDA transmission

If the printer receives a command that requires transmission of data from the remote station during IrDA
transmission, and then stores the data in the transmission buffer and transfers them at transmit timing to
the remote station.

The printer clears a response data in the transmission buffer when transmission to the remote station is
disconnected for busy state. When the remote station is in disconnection, the printer does not store the
data in the transmission buffer and the data is cleared.

However the printer transfers the status regardless of the remote station state when initial automatic
status transmission is enabled.
The printer transfers status when the remote station is connected again if automatic status transmission
has not deactivated by power off.

(NOTE) Be aware that if the transmission buffer becomes full, the printer does not print

until the buffer is available.

amount of the input buffer becomes 512 bytes or less after subtracting the field number of the data text
indicated in heading text.

(4) Input buffer full processing when receiving data

Upon receiving data, the printer sends WACK supervisory sequence to a host device for requiring
temporarily delay of the data output from the host device as the input buffer full state when the
remaining amount of the input buffer is 255 bytes or less.
Then, the printer sends the ACK supervisory sequence to the host device to restart data transmission
when the remaining amount of the input buffer is 512 bytes or more.

Turning ON / OFF the printer and changing the mode to the print-ready can be performed by the POWER
switch.

(NOTE) Always use the POWER switch to turn off the printer.

Do not power off the printer by removing the AC adapter or the battery pack. If
doing so, the memory may be damaged.

5.4 FEED SWITCH

The paper can be fed by the FEED switch.
The action differs depending upon SWDIP3-8 of the function settings.

 Roll Paper mode

The printer feeds a small amount of thermal paper by pressing this switch once and the switch is

held down, the thermal paper is fed continuously.

 Mark Roll Paper mode

The printer feeds the paper until paper mark detection by pressing this switch once.

The printer stops its operation if the printer does not detect the mark after feeding the thermal

paper up to paper length which is set.

The amount of maximum paper length to mark detection can be set by Set default/Set test print

header (DC2 'i') command (6.5.25 Auxiliary Function Commands). The default value is 300 mm.

The printer does not feed the thermal paper if pressing FEED switch in the following case.

 When the paper cover opens

 When power supply voltage is larger than 9.7V.

 When the printer is in the download mode. (For the download mode, refer to 6.5.26 Download

6.2 FUNCTION CODES

One of the following control codes is attached to the beginning of each command. These control codes are
also called function codes.

HT(09H), LF(0AH), VT(0BH), FF(0CH), CR(0DH), SO(0EH), DC2(12H), DC3(13H), DC4(14H),
CAN(18H), ESC(1BH), FS(1CH), GS(1DH)

Function codes may or may not have parameters or image data.

The number of bytes per command differs based on the type of command. Some commands are only 1 byte
long, while some are up to several hundred bytes in length.

6.3 CHARACTER CODES

This section describes character codes.

The character code range and User-defined character codes are different depending on JIS code system or
Shift JIS code system which is selected with the Kanji Code System Select command (FS 'C').

6.3.1 JIS Code System

When the JIS Code System is selected with the Kanji Code System Select command (FS ‘C’), Kanji

characters
can be printed using 2-byte character codes after Kanji mode is selected with the Kanji Mode Specify
command (FS '&').

The command functions as 1-byte character code or the first or second byte of 2-byte character code.
If a command is input in 2-byte character codes, the next data is always processed as the first byte. However,
the next data is 1-byte character code for Cancel Kanji Mode, FS '.'.
If a command is input as the second byte of 2-byte character code, the first byte is ignored.

(1) 1-byte character codes

00H - 1FH: Commands are processed as commands.

20H - 7EH: The codes are processed as 1-byte character code.

7FH: Ignored (except that when 7FH is defined as downloaded character and download

character operation is effective).

80H - FEH: The codes are processed as 1-byte character code.

6.4 MEMORY

Check remaining memory size when using optional fonts, routine command or stamp. Refer to this section to
use those functions.

6.4.1 External RAM Memory

(1) Memory

area

The printer has 232280 bytes of memory for User-defined characters, downloaded characters, optional
fonts, routine command and stamp.
Set or clear memory area for each function.
Setting of the memory area means to create a partition for certain function exclusively.
Clearing the memory area means to remove a partition for a certain function.

Usually users do not need to check it, however, make sure that the required memory does not exceed the
remaining memory size when using optional fonts, routine command, and stamp.
The following memory sizes shown in Table 6-2 are set right after initialization.

Optional fonts 0 Available

Routine command (DC2 'E') 0 Available

Stamp 0 Available

Memory area of User-defined characters and downloaded characters are set at initialization.
Memory area can be cleared by a command and can be increased for optional fonts, routine command or
stamp.
When registering optional fonts, routine command or stamp, always check the remaining memory size.
Registering data that exceeds the remaining memory size is ignored.
When setting optional fonts, fixed size format, fixed size parameters, or memory area is set automatically
by command input.

When setting memory area, memory control information is always added to the head of the memory area.
Number of bytes for memory control information differs according to each function. The number of bytes
for memory control information is shown in Table 6-3.

(2) Capacity of memory size

Allocated memory size depend on used function. User-defined character and downloaded character is
allocated size of 9784 and 6248 bytes respectively. Optional fonts, routine function or stamp is allocated
size of (number of data + Memory control Information). Moreover, registration of routine function and
stamp requires the above-mentioned size per registration data.

(3) Precautions for stamp function

Do not use the commands such as which to be allocated or freed as listed below during stamp operation.

Table 6-4 Commands for Allocating or Freeing Memory Area

Command Command name

DC2 'T' Stamp Define

DC2 'U' Stamp Clear

DC2 'P' Define optional font

DC2 'Q' Erase optional font

DC2 'E' 0 Set routine format

DC2 'E' 3 Delete all routine data

DC2 'z' 0 Page Mode Select

DC2 'D' Downloaded characters area operation

DC2 'G' User-defined character area operation

DC2 'R' User Area Initialization

If the commands listed in Table 6-4 are input during selection of the stamp, the stamp selection is
canceled.

(4) Initialization of memory

The printer does not erase the content of the memory using the AC adapter or the battery pack with active
voltage even if Reset command or Power off command is input or the printer is turned the power off.
However, the printer initializes the memory during its next start-up when disconnecting the power supply
or executing the User Area Initialization command.

(5) Memory usage at two-dimensional bar code function

At two-dimensional bar code print, empty area of the external RAM is used temporarily at bar code print.
The two-dimensional bar code printing performs depending on their parameter, available memory
capacity and settable data size as described below:

 When the parameter of the command is outside the range:

CPU ignores the part outside and processes the remaining data as normal codes.

 When the available memory capacity is short:

All of data is processed as normal code.

 When the command is normal and memory area has been allocated but the data more than
maximum data size is specified:
All of the data is discarded. Since settable data size varies depending on the type of
two-dimensional bar codes, refer to each explanation of two-dimensional bar code commands.
Moreover, note that settable data size changes in accordance with the value of specified parameter.

6-10

 When the command is normal and memory area has been allocated, but the bar code cannot be

printed within printable area:
The command is ignored.

 When the command is normal, memory area has been allocated and the bar code can be printed
within printable area:
The two-dimensional bar code is printed.

The necessary empty capacity differs according to types and sizes of bar codes.

optional font and template data can be used dedicated memory area. Moreover, FLASH memory has shared
memory area as 256K byte user area for routine function and stamp.

Data except template data stored into FLASH memory is used when that is not present into extended RAM.
If data is present in both of FLASH memory and extended RAM, the printer treats data in extended RAM as
priority.
When allocating memory area for User-defined character or downloaded character in extended RAM, the
printer copies data of User-defined character or downloaded character if those data are present in FLASH
memory.

(1) User area in FLASH memory management

Memory in the user area has the following states:

 In use state (storage state)
 Released state (Erasable state)
 Empty state

In use

Release
Empt

All Extension memories are in “Empty state” at shipping.

When some data is saved in the memory, the memory turns to “In use state”.
When the data is in use state is released, the memory turns to “Released state (Erasable condition).” This
area cannot be used again in this state.

[1] Shipping state

Empty state

[2] State that some data are

registered.

Data (1) In use state

Empty state

[3] State that the registered

data is released.

Data (1) Released state

[5] State that the Extension Memory Area

Control command (DC2*1) is executed.

Data (2) In use state

Data (3) In use state

Data (5) In use state

Empty state

6-16

When data storage and release are repeated, the memory state turns to the [4] state.
To use the “Released state (Erasable state)” area again, execute the User Area Defragment (DC2 '*' '1')
command.
The [5] shows the memory state after the command is executed.

Executing Remaining User Area Response (DC2'*' '2') command to check the current remaining area.
Remaining Memory Response command in user area responds the current available amount of FLASH
memory.

(2) Precautions on data in FLASH memory when rewriting, freeing and allocating

The maximum rewritable number of the FLASH memory is approximately 100000 times. Execute the
User Area Defragment command after getting low memory for restraining the numbers of the memory
rewriting.

Do not turn the power off during FLASH memory writing/erasing. If doing so may cause FLASH memory
damage and it may not work. To confirm the FLASH memory writing/erasing, send Execute Response
Request (DC2 ‘j’) command (6.5.23 Status Commands) behind the command as the above-mentioned
and check response code.

6.5.5 Print and Paper Feed Commands

CR Print and Carriage Return

Code 0DH

Function Functions the same as an LF command.

If the line buffer contains data and the line spacing amount is smaller than the character height,

the data in the buffer is printed and line feeding is performed by the character height.

LF Print and Line Feed

Code 0AH

Function After data in the line buffer is printed out, the printer feeds one line.

The next print starting position becomes the beginning of the next line (left margin).

If the line buffer contains data and the line spacing is smaller than the character height, the data
in the line buffer is printed and one line is fed by the character height.
If the line buffer does not contain data before this code is received, the printer only feeds one line.
The select expanded character mode with automatic cancellation selected by SO is canceled.
The LF command that follows CR is ignored.

FF Page Feed (form feed)

Code 0CH

Function When page length is specified, the printer performs page feed up to specified page length after

data in the line buffer is printed out.
When page length is not specified, the printer performs page feed up to mark by specified value
with Set default/Set test print header (DC2 'i')command after data in the line buffer is printed out.
The next print starting position becomes the beginning of the next line (left margin).

The select expanded character mode with automatic cancellation selected by SO is canceled.

In the cut paper mode:

If an out-of-paper error occurs during page feeding, the page feed ends at the time. Then, the
paper is fed at low speed. When new paper is loaded, it is not fed, and the page insertion
position is regarded as the beginning of the page.

In the Roll Paper mode:

When page length is not specified, this command is ignored. When page length is specified, if an
out-of-paper error occurs during page feeding, the page feed ends at the time. When new paper
is loaded, it is not fed, and the page insertion position is regarded as the beginning of the page.

In the Mark Roll Paper mode:

The paper mark is detected by this command and paper form feed is executed. If an
out-of-paper error occurs, the printer operation is same as in the Roll Paper mode.

6-27

ESC 'J' n Print and Feed paper

Code 1BH 4AH n

n255

Function Prints the data in the print buffer and feeds the paper one dot line.

If the line buffer contains data and n is smaller than the character height, the data in the line

buffer is printed and one line is fed by the character height.
If the line buffer contains data, the select expanded character mode with automatic cancellation
selected by SO is canceled.
If the line buffer does not contain data before this code is received, the printer only feeds n dot
lines.
The predetermined line spacing remains unchanged.

GS '<' Marked Paper Form Feed

Code 1DH 3CH

Function Performs the marked paper form feed.

This command is effective only when marked paper is selected.

In the Mark Roll Paper mode, the printer performs its operation as same as Page feed (FF)

command.

In the Mark Roll Paper mode, the printer executes the paper form feed to the cutting position. If

data is remaining in the line buffer, the printer executes paper feed after printing data in the line
buffer.

The select expanded character mode with automatic cancellation selected by SO is canceled.

Default The default tab positions are at intervals of 8 characters.

VT Execute Vertical Tab

Code 0BH

Function Feeds the paper to the next vertical position.

If the line buffer contains data, it is printed and the print position moves to the next tab position.

When a VT command is input after the last vertical tab position, the command functions in the
same way as the FF command.
If the next vertical tab position is not set, the command functions in the same way as the LF
command.
If the print position enters the perforated line skip area when a VT command is executed, the
paper is fed to the beginning of the next page.
The vertical tab position is set using the ESC 'B' command.

6.5.8 1-byte characters Definition Commands

ESC '%' n Set/Cancel Download Character Set

Code 1BH 25H n

Function Sets or cancels the download character set.

Only the least significant bit of n is valid.

n = 0: Cancel the download character set.
n = 1: Set the download character set.

When the download character set is set, it can be printed.

When the download character set is input with undefined character code, the optional font or the
selected internal character set is printed. However, the 7FH character code is ignored.
If the download character set and optional font are defined in the same character code and both
are selected, the download character set is given priority.

Default n=0 (Cancel)

ESC '&' s n m {DATA} Define Download Characters

Code 1BH 26H s n m {d1 d2•••dk}

s=0

nm7FH

20H

Function Defines 1-byte characters in the download character set.

s indicates the character set number of the download character.

n is the beginning of the definition of download characters and m is the end of the definition of

download characters. If either n or m is defined, n must be equal to m.
If n or m is out of range, the data out of range is ignored and the following data will be processed
as normal data.
The font size of the download character registered is decided by current selected font size.
The download characters for 24- or 16-dot fonts are defined simultaneously because both are
registered in separate areas.

d indicates the defining data. The bit corresponding to the dot to be printed is set to 1, and the bit

corresponding to the dot not to be printed is set to 0.
Multiple character codes can be defined at the same time.
If the previously defined character code is defined again, it is overwritten.
The size of data per character for a selected font is as follows:
24-dot font : 48 bytes/character
16-dots font : 16 bytes/character
The total number of character patterns (k) is as follows:
24-dot font : k=48
16-dot font : k=16
Enter font data by using eight vertical dots as one byte.
If the download character area is freed up, ESC '&' is ignored and the following data will be
processed as normal data.
For 24-dot fonts, a character is defined as 24 x 16 dots. The following restrictions apply to the
actual printing. If the right space + character width is 16 dots or more, the character can be
printed as 24 x 16 dots. If it is 16 dots or less, only the (character width + character right-side
spacing) dots are printed. To print the whole character regardless of the character right-side
spacing, the font must be defined as 12 dots (horizontal) or less.

Function Allocates or frees the download character area.

Only the least significant bit (LSB) of n is valid.

n = 0 : Frees the download character area.
n = 1 : Allocates the download character area.
When the download area is freed up, the download character is erased and the download
character set specification is freed up. The following commands are ignored.
ESC '&' :Define download character
ESC '%' :Select/cancel download character set
The download character area after memory initialization is 6248 bytes long. If the download
character area is freed, the remaining memory capacity increases by 6248 bytes.
The remaining memory capacity must be at least 6248 bytes to reallocate the download
