2. 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 ╳24) every 8th character (9th, 17th, 25th, ... column).
[Reference] ESC D
LF
[Name] Printandlinefeed
[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
FF
[Name] Print and return to standard mode in page mode
[Format] ASCII FF
Hex 0C
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
CR
[Name] Print and carriage return
[Format] ASCII CR
Hex 0D
Decimal 13

THERMAL RECEIPT PRINTER 5
[Description] When automatic line feed is enabled, this command functions the same as LF;
when automatic line feed is disabled, this command is ignored.
[Details] • Sets the print starting position to the beginning of the line.
• The automatic line feed is ignored with a serial interface model.
• This command is set according to the DIP switch 1-1 setting with a parallel
interface model.
[Reference] LF
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.
[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 nL nH d1...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.

THERMAL RECEIPT PRINTER 6
 The printer transmits the status without confirming whether the host computer
can receive data.
 The printer executes this command upon receiving it.
 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.

[Range] 1<=n <=2
[Description] Responds to a request from the host computer. n specifies the requests as
follows:
n Request
1 Recover from an error and restart printing from the line where the error occurred
2 Recover from an error aft clearing the receive and print buffers
[Details]  This command is effective only when an auto-cutter error occurs.
 The printer starts processing data upon receiving this command.
 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

THERMAL RECEIPT PRINTER 8
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.

0 Drawer kick-out connector pin 2.
1 Drawer kick-out connector pin 5.
The pulse ON time is [ t  100 ms] and the OFF time is [ t  100ms].
[Details]  When the printer is in an error status when this command is processed, this
command is ignored.
 When the pulse is output to the connector pin specified while ESC p or DEL
DC4 is executed while this command is processed, this command is ignored.
 The printer executes this command upon receiving it.
 With a serial interface model, this command is executed even when the printer
is off-line, the receive buffer is full, or there is an error status.

THERMAL RECEIPT PRINTER 9
 With a parallel interface model, this command cannot 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.
 If print data includes the same character strings as this command, the printer
performs the same operation specified by this command. The user must
consider this.
 This command should not be used within the data sequence of another
command that consists of 2 or more bytes.
 This command is effective even when the printer is disabled with ESC = (Select
peripheral device).

[Description] Sets horizontal tab positions.
• nspecifies the column number for setting a horizontal tab position from the
beginning of the line.
• kindicates the total number of horizontal tab positions to be set.
[Details] • The horizontal tab position is stored as a value of [character width
╳ n]
measured from the beginning of the line. The character width includes the
right-side character spacing, and double-width characters are set with twice the
width of normal characters.
• This command cancels the previous horizontal tab settings.

• When setting n= 8, the print position is moved to column 9 by sending HT.
• Up to 32 tab positions ( k= 32) can be set. Data exceeding 32 tab positions is
processed as normal data.
• Transmit [ n] k in ascending order and place a NUL code 0 at the end.
• When [ n] k is less than or equal to the preceding value [ n] k-1, tab setting is
finished and the following data is processed as normal data.
• ESC D NUL cancels all horizontal tab positions.
• The previously specified horizontal tab positions do not change, even if the
character width changes.
• The character width is memorized for each standard and page mode.
[Default] The default tab positions are at intervals of 8 characters (columns 9, 17, 25,...) for
font A (12 ╳24).

[Description] Prints the data in the print buffer and feeds the paper [ n
╳ vertical or horizontal
motion unit] inches.
[Details] • After printing is completed, this command sets the print starting position to the
beginning of the line.
• The paper feed amount set by this command does not affect the values set by
ESC 2 or ESC 3.
• The horizontal and vertical motion unit are specified by GS P.
• The GS P command can change the vertical (and horizontal) 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 printer uses the vertical motion unit ( y).
• 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 line spacing is 1016mm (40 inches). When the setting value
exceeds the maximum, it is converted to the maximum automatically.

[Description] Switches from standard mode to page mode.
[Details] • This command is enabled only when processed at the beginning of a line in
standard mode.
• This command has no effect in page mode.
• After printing by FF is completed or by using ESC S, the printer returns to
standard mode.
• This command sets the position where data is buffered to the position specified
by ESC T within the printing area defined by ESC W.
• This command switches the settings for the following commands (in which the
values can be set independently in standard mode and page mode) to those for
page mode:
① Set right-side character spacing: ESC SP, FS S
② Select default line spacing: ESC 2, ESC 3
• Only valve settings is possible for the following commands in page mode; these
commands are not executed.
①Turn 90°clockwise rotation mode on/off: ESC V
②Select justification: ESC a
③Turn upside-down printing mode on/off: ESC {
④Set left margin: GS L
