[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,

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 trans-
mitted andthen 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.
DLE EOT n (*)

•
• 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.
• 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.
Even though the printer is not selected using ESC = (select peripheral device), this command is effective.

[Details]
[Reference] DLE EOT
• 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 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
possib-ility 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.

[Description] Selects a bit-image mode using m for the number of dots specified by nL and nH, as follows:
[Details] • If the values of m is out of the specified range, nL and data following are processed as normal data.
• The nL and nH indicate the number of dots of the bit image in the horizontal direction. The number of dots is calculated
by nL + nH ×256.
• If the bit-image data input exceeds the number of dots to be printed on a line, the excess data is ignored.
• d indicates 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):
① The width of the printing area is extended to the right to accommodate the amount of data.
② If step ① does 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:

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).

set to (vertical printable area - vertical starting position).
• The horizontal and vertical motion unit are specified by GS P. Changing the horizontal or vertical motion unit does not
affect the current printing area.
• The GS P command can change the horizontal (and vertical) motion unit.
However, the value cannot be less than the minimum horizontal movement amount, and it must be in even units of
minimum hori-zontal movement amount.
• Use the horizontal motion unit ( x) for setting the horizontal starting position and printing area width, and use the
vertical motion unit ( y) for setting the vertical starting position and printing area height.
• When the horizontal starting position , vertical starting position, printing area width, and printing area height are defined
as X, Y, Dx, and Dy respectively, the printing area is set as shown in the figure below.
• This printable area for this printer is approximately 72 mm in the horizontal direction and approximately 117.3 mm
