2. 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 command 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.
(5) Printable area
The maximum range of print area under the printer’s specifications. The max print area of the
printer is 400/160 inch.
(6) Ignore
The state in which all codes, including parameters, are read in and discarded, and nothing
happens.
(7) Invalidation
The state in which command codes are read in and discarded, and parameters are processed
as normal data.
(8) Inch
A unit of length. One inch is 25.4 mm.
(9) MSB
Most Significant Bit
(10) LSB
Least Significant Bit
2. 3 Control Commands
1．HT
[Name] Horizontal Tab
[Format] ASCII HT
Hex 09
Decimal 10
[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.
• The default setting of the horizontal tab position for the paper roll is font B (9 X 9) every 8
characters (9th, 17th, 25th, ... column).
[Reference] ESC D
2．LF

4．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] • In sending status, printer sends a byte without validation of DSR signal.
• 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.
• When use GS a to enable Automatic Status Back (ASB), the status transmitted by DLE
EOT and the ASB status must be differentiated by using the table in Appendix D.
• This command is valid even when the printer is disabled with ESC = (Select peripheral
device).
• This command is being processed as soon as received by the printer.
[Note] • 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.

[Description] Responds to a request from the host computer.
n = 0: Recover from an error;
n = 2: Recover from an error after clearing the receive and print buffers;
[Details] • The command n=0 is ignored unless the error caused by paper shortage has
occurred.
• The command n=2 is effective only when a mechanical error or 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.
• 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.
[Note] • ESC * m nL nH [ d ] nL + 2 5 6 nH d1=<10>H d2=<05>H d3=<1>HThe
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.

• nL, nH Sets the offset value to (nL+nH×256)×0.176mm.
• GS FF and GS V is valid only when this command is executed.
• Setting offset of the print starting position (a=1) is enabled in GS FF.
• Setting offset of the paper cutting/tearing position (a=2) is enabled in GS V m.
• Default value of nL and nH is 0, viz., when the black mark sensor senses the black
mark, the print head position corresponding to where on the paper is set as the print
starting position, and the paper cutting/tearing position corresponding to where on the
paper is set as the paper cutting/tearing position.
• Explanation of the calculation of the paper cutting/tearing position offset and print
starting position offset.
1. When the length (L) between paper cutting/tearing position and black mark position
is the same as the printer inherency mechanism value (L0), and the length (Q)
between print starting position and printer inherency mechanism value (Q0), offset
set by GS （ F is 0. (Chart 1)
2. When length (L) between paper cutting/tearing position and black mark position is
less than the printer inherency mechanism value (L0) (Chart 2), offset set by GS
（ F is calculated as follows:
Paper cutting/tearing position offset = (L0－L)/0.176 dots
When length (L) between paper cutting/tearing position and black mark position is
larger than the printer inherency mechanism value (L0) (Chart 3), offset set by GS
（ F is calculated as follows:
Paper cutting/tearing position offset = (L0 + length of two neighbor black mark －
L)/0.176 dots
Note: When setting the paper cutting/tearing position offset,
parameter a of GS ( F is 2. (a = 2)
3. When paper cutting/tearing position offset is not 0 or the length (Q) of print starting
position is larger than the printer inherency mechanism value (Q0), offset set by GS
（ F is calculated as follows:
Print starting position offset = (Q-Q0)/0.176+ paper cutting/tearing position offset
Note: When setting the paper cutting/tearing position offset,
parameter a of GS ( F is 2. (a = 1)
4. Inherence mechanism value of mechanism DP330:
L0=43mm, Q0=18mm
When the mechanism is installed in the printer enclosure, values of L0 and Q0 will
change, that is,
L0=43+ΔL, Q0=18+ΔL
5. ΔL calculation method:
1) Load the paper first, and trim the paper edge;
2) Send 20 characters “E” to the printer and print these out;
3) Feed the paper to proper position, and measure the length within the paper end
and the top of “EEEEEEEEEEEEEEEEEEEE”, which minus 18ms equals ΔL.
Examples for the black mark position control for specified paper.
The paper tearing position assumed to be the printer cutter position, that is L0=43mm and
Q0=18mm
【Example 1】Paper: Cutting/tearing position is on the printed black mark position, which is
25mm distance away from the print starting position.
• Cutting/tearing paper position offset calculation:
For black mark position is the same as the cutting/tearing paper position, that is L=0, then
Cutting/tearing paper position offset = (43-0) / 0.176 = 244 dots
• Set the cutting/tearing paper position offset by the following command:
GS （ F <4><0><2><0><244><0>
• Print starting position offset calculation:
(25-18)/0.176+244=284 dots
• Set the print starting position offset by the following command:
GS （ F <4><0><1><0><28><1>
• After finished these steps, and when every receipt is printed:
Feed paper to the print starting position by using command GS FF;
Data is sent to the printer and printed out line by line;
Feed paper to the cutting/tearing position by using command GS V m, where the receipt
can be cut or tear.
【Example 2】Paper: The distance between cutting/tearing position and black mark
position is 12mm, and that between print starting position and
cutting/tearing position is 18mm.
• Cutting/tearing paper position offset calculation:
For the length within black mark position and the cutting/tearing paper position is less
than L0 (43mm), then
Cutting/tearing paper position offset = (43-12)/0.176=176 dots
• Set the cutting/tearing paper position offset by the following command:
GS （ F <4><0><2><0><176><0>
• Print starting position offset calculation:
(18-18)/0.176+176=176 dots
• Set the print starting position offset by the following command:
GS （ F <4><0><1><0><176>< 0>
• After finished these steps, and when every receipt is printed, the command list to use is
the same as the one in Example 1.
【Example 3】Paper: Paper length is 140mm;
Length within black mark position and cutting/tearing paper position is 130mm;
Length within print starting position and cutting/tearing paper position is 20mm.
• Cutting/tearing paper position offset calculation:
For the length within black mark position and the cutting/tearing paper position is larger than
L0 (43mm), then
Cutting/tearing paper position offset = (43+140-130)/0.176=301 dots
• Set the cutting/tearing paper position offset by the following command:
GS （ F <4><0><2><0><45><1>
• Print starting position offset calculation:
(20-18)/0.176+301=312 dots
• Set the print starting position offset by the following command:
GS （ F <4><0><1><0><56><1>
• After finished these steps, and when every receipt is printed, the command list to use is the
same as the one in Example 1.
Note:
1. When both cutting/tearing paper position offset and print starting position offset is 0, only
need to use command GS V m to complete the location print.
2. When cutting/tearing paper position offset is not equal 0, GS （ F is used to set the
cutting/tearing paper position offset to a=2 and the print starting position offset to a=1.
3. Only when print starting position is set, GS FF can be use to feed paper to the print
starting position, otherwise, situations of unfaithful location or feeding a blank paper may
happen.
4. Once GS （ F is used to modify the previous-set offset, situations of unfaithful location or
feeding a blank paper may happen, but the next receipts will be print correctly.
