12-Nozzle serial configuration
(3) Printing directions
Bi-directional printing (logical seeking)
(4) Printing speed
Approx. 6.5 LPS (at 42 columns)
(LPS: Lines Per Second)
Note1: If the printing duty ratio is too high, the printing quality is poor by the duty limit.
In such circumstances, the printing speeds shown above cannot be guaranteed.
Note2: When select 2-color combination printing, the printing speed goes down
compared to mono-color printing. It is caused by the switching operation in the
printer.

COMMANDS
3.3 International character set
3.4 Using the control panel
Most of the functions of this printer are governed by software, but you can monitor the
printer’s status by looking at the lights on the control panel and for some procedures you
will use the buttons.
2002. 1. 8. Programmer’s Guide 13

COMMANDS
3.4.1 Power (LED)
This indicator light is on when the power is turned on. It blinks when the printer is the self-
test printing standby state.
Always wait until this indicator light stops blinking before you start using the printer and
before you turn it off.
3.4.2 Error (LED)
When this indicator light is on but not blinking, it means that the printer is no paper or
almost out of paper or the printer covers are open. When this light is blinking, there is an
error. If you see this light is blinking, turn off the printer for a few seconds and then turn it
back on.
3.4.3 Cartridge (LED)
The right indicator is for the right cartridge and the left indicator for the left cartridge. If the
printer is a single color printer, the left cartridge indicator will be used. In the most cases,
the left cartridge is black, and the right is a color. This indicator light (LH/RH) blinks when
the cartridge is almost out of ink and stays on when the cartridge(s) is removed.
3.4.4 Clean (BUTTON)
Use this button to clean the printer head or to enter MENU mode.
3.4.5 Feed (BUTTON)
Use this button to feed paper or to start self-test and for hexadecimal dump mode.
3.5 DIP switch setting
Although the factory settings are best for almost all users, if you have special
requirements, you can change the DIP switch.

COMMANDS
4. COMMANDS
4.1 Command Notation
XXXX
[Name] The name of the command.
[Format] The code sequence.
[Range] Gives the allowable ranges for the arguments.
[Description] Describes the command’s function.
[Notes] Provides important information on setting and using the printer
command, if necessary. Item(s) marked with * indicates "important
notice".
[Default] Gives the default values,(if any) for the command arguments.
[Reference] Lists related commands.
ASCII indicates the ASCII equivalents.
Hex indicates the hexadecimal equivalents.
Decimal indicates the decimal equivalents.
[ ] kindicates the contents of the [ ] should be repeated ktimes.
4.2 Explanation of Terms
(1) Reception buffer
The reception buffer is a buffer that stores, as is, the data received from the host (the
reception data). The reception data is stored in the reception buffer temporarily, and is
then processed sequentially.
(2) Print buffer
The print buffer is a buffer that stores the image data to be printed.
(3) Print buffer full
This is the state where the print buffer is full. If new print data is input while the print
buffer is full, the data in the print buffer is printed out and a line feed is executed. This
is the same operation as the LF operation.
(4) Start of line
The start of line state satisfies the following condition:
▪ There is no print data (including spaces and portions of data skipped due to HT)
currently in the print buffer.
(5) Printable area
The maximum range within which printing is possible under the printer specifications.
The printable area for this printer is 504/208 inches.
2002. 1. 8. Programmer’s Guide 16

COMMANDS
(6) Inch
A unit of length. One inch is 25.4mm.
(7) MSB
Most Significant Bit
(8) LSB
Least Significant Bit
4.3 Exception Processing
4.3.1 Undefined codes
This term refers to the codes ranging from 00H to 1FH in the character code table. If a
code in this range that is not defined as a command is input, that code (one byte) is read
in and discarded, and subsequent data is processed as normal data.
Example : 30H, 31H, 03H, 32H, 0AH, 33H
If the above data string is input, the printer reads in and discards "03H" as an undefined
code.
Note that 0AH is defined as a command (LF). As a result, the data string that is actually
processed is: 30H, 31H, 32H, 0AH, 33H
4.3.2 Undefined commands
If the data following ESC (1BH) or GS (1DH) is not defined as a command, then the two
bytes (ESC/GS and the code that follows) are read in and discarded.
Example: 30H, 1BH, 22H, 31H, 32H
If the above data string is input, the printer discards the data 1BH and 22H as undefined
commands.
As a result, the data string that is actually processed is: 30H, 31H, 32H
4.3.3 Settings outside the defined range
If a value outside of the defined range is input for a command that takes parameters, that
command is ignored and the previous value for that setting remains unchanged. In the
case of a command that takes multiple parameters, command processing is halted the
moment that a value outside of the defined range is input and subsequent values are
processed as normal data.
Example:1BH, 52H, 15H
If the above data string is input, 1BH and 52H are defined as a command (ESC R), but
the parameter 15H is outside of the defined range. As a result, the printer reads in and
discards the data string 1BH, 52H, 15H. Accordingly, the previously set international
character set is not changed.

COMMANDS
4.4 Command descriptions
HT
[Name] Horizontal tab
[Format] ASCII HT
Hex 09
Decimal 10
[Description] Moves the print position to the next horizontal tab position.
[Notes]
▪ This command is ignored unless the next horizontal tab position
has been set.
▪ Horizontal tab positions are set with ESC D.
▪ The default tab positions are at intervals of 8 characters
(columns 9, 17, 25..) for the font B (12×12).
[Reference] ESC D
LF
[Name] Print and line feed
[Format] ASCII LF
Hex 0A
Decimal 10
[Description] Prints the data in the print buffer and feeds one line based on the
current line spacing.
[Note] This command sets the print position to the beginning of the line.
[Reference] ESC 2, ESC 3
2002. 1. 8. Programmer’s Guide 18

COMMANDS
CR
[Name] Print and carriage return
[Format] ASCII CR
Hex 0D
Decimal 13
[Description] This command prints the data in the print buffer and does not feed
the paper.
[Note] Sets the print starting position to the beginning of the line
[Reference] LF
DLE EOT n
[Name] Real-time status transmission
[Format] ASCII DLE EOT n
Hex 10 04 n
Decimal 16 4 n
[Range] 1 ≤n≤4
[Description] Transmits the selected printer status specified by n in real time,
according to the following parameters:
n = 1: Transmit printer status
n = 2: Transmit off-line status
n = 3: Transmit error status
n = 4: Transmit paper roll sensor status
[Notes]
▪ This command should not be used within the data sequence of
another command that consists of 2 or more bytes. For example,
If you attempt to transmit ESC 3 nto the printer, but DTR (DSR
for the host computer) goes to MARK before n is transmitted
and then DLE EOT 3 interrupts before n is received, the code
<10>H for DLE EOT 3 is processed as the code for ESC 3
<10>H.
