1.2 Explanation of Terms
(1) Receive buffer
The receive buffer is a buffer that stores, as is, the data received from the host (the reception data). The
reception data is stored in the receive 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 bit image data) currently in
the print buffer.
•There is no print data (including portions of data skipped due to HT)
•The print position is not specified by the ESC $ or ESC \ command.
(5) Printable area
The maximum range within which printing is possible under the printer specifications. The printable area
for this printer is as follows:
① The length of the horizontal direction in standard mode:
approximately 72.1 mm {576/203"}
② The length of the horizontal direction in page mode:
approximately 72.1 mm {576/203"}
③ The length of the vertical direction in page mode: approximately 117.3 mm {1662/360’1}
(6) Printing area
Printing range is set by the command. It must be printing area ≦printable area.

-------------Thermal Printer-------------
2
(7) Ignore
The state in which all codes, including parameters, are read in and discarded, and nothing happens.
(8) Inch
A unit of length. One inch is 25.4 mm.
(9) MSB
Most Significant Bit
(10) LSB
Least Significant Bit
(11) Base line
Standard position when character data is stored in the print buffer.
Normal character in standard mode and page mode:

1.3 Control Commands
HT
[Name] Horizontal tab
[Format] ASCII HT
Hex 09
Decimal 9
[Description] Moves the print position to the next horizontal tab position.
[Details]
•This command is ignored unless the next horizontal tab position has been set.
•If the next horizontal tab position exceeds the printing area, the printer sets the printing position to
[Printing area width + 1].
•Horizontal tab positions are set with ESC D.
•If this command is received when the printing position is at [printing area width
+ 1], the printer executes print buffer-full printing of the current line and horizontal tab processing
from the beginning of the next line.
•The default setting of the horizontal tab position for the paper roll is font A (12 X 24) every 8th
character (9th, 17th, 25th,... column).
[Reference] ESC D
LF
[Name] Print and line feed
[Format] ASCII LF
Hex OA
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
FF（*）
[Name] Print and return to standard mode in page mode
[Format] ASCII FF
Hex OC
Decimal 12
[Description] Prints the data in the print buffer collectively and returns to standard mode.
[ Details] The buffer data is deleted after being printed.
•The printing area set by ESC W is reset to the default setting.
•The printer does not execute paper cutting.
•This command sets the print position to the beginning of the line.
•This command is enabled only in page mode.
[Reference] ESC FF, ESC L, ESC S

-------------Thermal Printer-------------

[Details] •This command is enabled only in page mode.
•If data that existed in the previously specified printing area also exists in the
currently specified printing area, it is deleted.
[Reference] ESC L, ESC W
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
[Details] •The status is transmitted whenever the data sequence of <10>H<04>H< n>
(1 ≤n ≤4) is received.
Example:
In ESC * m m_nHd1...dk, d1=<10>H, d2=<04>H, d3=<01>H
•This command should not be used within the data sequence of another
command that consists of 2 or more bytes.
Example:
If you attempt to transmit ESC 3 n to 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.
•Even though the printer is not selected using ESC = (select peripheral device),
this command is effective.
•The printer transmits the current status. Each status is represented by onebyte
data.
•The printer transmits the status without confirming whether the host computer
can receive data.
•The printer executes this command upon receiving it.
CAN(*)
[Name] Cancel print data in page mode
[Format] ASCII CAN
Hex 18
Decimal 24
[Description] In page mode, deletes all the print data in the current printable area

•This command is executed even when the printer is off-line, the receive buffer is
full, or there is an error status with a serial interface model.
•With a parallel interface model, this command can not be executed when the
printer is busy. This command is executed even when the printer is off-line or
there is an error status when DIP switch 2-1 is on with a parallel interface
model.
•When Auto Status Back (ASB) is enabled using the GS a command, the status
transmitted by the DLE EOT command and the ASB status must be
differentiated.

•With a parallel interface model, this command can not be executed when the
printer is busy. This command is executed even when the printer is off-line or
there is an error status when DIP switch 2-1 is on with a parallel interface model.
•The status is also transmitted whenever the data sequence of <10>H<05>H< n> (1
< n < 2) is received.
Example:
In ESC * m nl nH dk, d1 = <10>H, d2 = <05>H, d3 = <01>H
•This command should not be contained within another command that consists of
two or more bytes.
Example:
If you attempt to transmit ESC 3 n to the printer, but DTR (DSR for the host
computer) goes to MARK before n is transmitted, and DLE ENQ 2 interrupts
before n is received, the code <10>H for DLE ENQ 2 is processed as the code
for ESC 3 <10>H.
•DLE ENQ 2 enables the printer to recover from an error after clearing the data in
the receive buffer and the print buffer. The printer retains the settings (by ESC !,
ESC 3, etc.) that were in effect when the error occurred. The printer can be
initialized completely by using this command and ESC@. This command is
enabled only for errors that have the possibility of recovery, except for print head
temperature error.
•When the printer is disabled with ESC = (Select peripheral device), the error
recovery functions (DLE ENQ 1 and DLE ENQ 2) are enabled, and the other
functions are disabled.

•If the bit-image data input exceeds the number of dots to be printed on a line, the excess
data is ignored.
•dindicates the bit-image data. Set a corresponding bit to 1 to print a dot or to 0 to not print
a dot.
•If the width of the printing area set by GS L and GS W less than the width required by the
data sent with the ESC * command, the following will be performed on the line in question
(but the printing cannot exceed the maximum printable area):
①The width of the printing area is extended to the right to accommodate the
amount of data.
②If step ①does not provide sufficient width for the data, the left margin is
reduced to accommodate the data.
•After printing a bit image, the printer returns to normal data processing mode.
•This command is not affected by print modes (emphasized, double-strike, underline,
character size or white/black reverse printing), except upside-down printing mode.
•The relationship between the image data and the dots to be printed is as follows:
•When 8-dot bit image is selected:

ESC-n
[Name] Turn underline mode on/off
[Format] ASCII ESC - n
Hex 1B 2D n
Decimal 27 45 n
[Range] 0 ≤n ≤2, 48 ≤n ≤50
[Description] Turns underline mode on or off, based on the following values of n:
［Details] •The printer can underline all characters
(including right-side character spacing),
but cannot underline the space set by HT.
•The printer cannot underline 90 . clockwise rotated characters and white/black inverted
characters.
•When underline mode id turned off by setting the value of n to 0 or 48, the following
data is not underlined, and the underline thickness set before the mode is turned off
does not change. The default underline thickness is 1 dot.
•Changing the character size does not affect the current underline thickness.
•Underline mode can also be turned on or off by using ESC!. Note, however, that the last
received command is effective.
•This command does not affect the setting of Kanji characters.
[Reference] ESC!
[Description] Sets the line spacing to[n Xvertical or horizontal motion unit] inches.
[Details] •The line spacing can be set independently in standard mode and in page mode
•The horizontal and vertical motion unit are specified by GS P. Changing the horizontal or vertical
motion unit does not affect the current line spacing.
•The GS P command can change the horizontal (and vertical) motion unit. However, the value cannot be
less than the minimum vertical movement amount, and it must be in even units of the minimum vertical
movement amount.
•In standard mode, the vertical motion unit (y) is used.
In page mode, this command functions as follows, depending on the starting position of the printable
area:

①When the starting position is set to the upper left or lower right of the printable area using ESC T,
the vertical motion unit (y) is used.
②When the starting position is set to the upper right or lower left of the print able area using ESC T, the
horizontal motion unit (x) is used.
•The maximum paper feed amount is 1016 mm (40 inches). Even if a paper feed amount of more than
1016 mm (40 inches) is set, the printer feeds the paper only 1016 mm (40 inches).
[Default] Line spacing equivalent to approximately 4.23mm (1/6 inches).
