1 Overview
This manual classifies the printer commands into several kinds based on its functions, and also
describes the applications of relative commands in detail depending on its sorts. We hope that it is
helpful for programmers to get known of those commands.
1.1 Commands classification
This receipt printer commands are classified as below:
Print commands: used for printing and feeding paper;
Position commands: to control the print position;
Character commands: to set characters property;
Bitmap commands: to download bitmap and print, including NV bitmap;
Status commands: used for printer status query;
Other commands: used for periphery control, Micro-definition and initialization;
Command instruction refers to the detailed function of relative commands.
1.2 Key terms
Real-time commands – These commands are acted on immediately upon being received by the
printer.
Print buffers – used to store figure data to be printed;
Marked paper mode – Printer woks in the mode with marked paper;
Line beginning – The status after executing the commands like LF, CR, ESC J, ESC K, ESC d, ESC
e; namely the position for starting the print is at the beginning of print buffers.
Kanji character – Multi-byte code character is the character as simplified Chinese, traditional Chinese,
Japanese and Korean.
NV – Non-volatile memory in which data stored does not loss when power off.
ASB – Auto status back.
Font A – 9 x 9 dot matrix ASCII character.
Font B – 7 x 9 dot matrix ASCII character.
1.3 Command format
[Function] The name and function summary of commands;
[Format] The command expressed in ASCII, Hex and Decimal separately. If not specified, the
value in “range” part is decimal. For instance, in range” 1 ≤ n≤ 4”, ‘1’ is not an ASCII
code but a decimal number;
[Range] The value range of parameter in the command;
[Note] Explain the main features and application notices of commands;
[Default] The initial value used after the printer initialized;
[Relative] Other commands related to current commend;
[Demo] Example used for current or relative commands.

All command data in programming Demo use HEX. All normal font/characters are data.
There is no explanation for the data of command such as 42 43 which is data. The
font/character underlined and emphasized is a command such as
1B 40. All the data
inside parentheses after all commands in Demo is used to explain the meanings of this
command. The parentheses and data inside it is not the command to be transmitted to
the printer.

Decimal 27 75 n
[Range] 0 ≤ n ≤ 48
[Notes] Print the data in buffers and retract paper n dots [n x 0.176mm].
If n exceed the paper retraction range, the data in the buffers shall be printed but not
retract paper.
Paper retraction may cause the issues as below:

[Description] • n specifies the number of the defined NV bitmap.
• xL, xH specifies ( xL + xH × 256) in the horizontal direction for the NV bitmap.
• yL, yH specifies ( yL + yH × 256) in the vertical direction for the NV bitmap.
• d is bitmap data to be defined. In data the corresponding bit 1 means to print this point
and bit 0 means not to pint it.
[Notes] • Frequent command execution may cause damage the NV memory. Therefore, it is
recommended to write the NV memory 10 times or less a day.

• This command cancels all NV bitmaps that have already been defined by this command.
The printer cannot redefine only one of several data definitions previously defined. In
this case, all data needs to be sent again.
• During the processing of this command, the printer is in busy status; Because the data
now is being inputted into NV memory at that moment, the printer stops receiving other
commands. Hence during this command operation, other commands are not allowed to
be sent to the printer.
• This command is effective only when processed at the beginning of a line.
• This command defines n as the number of a NV bitmap. Numbers rise in order from NV
bitmap 01H. Therefore, the first data group [xL xH yL yH d1...dk] is NV bitmap 01H, and
the last data group [xL xH yL yH d1...dk] is NV bitmap n.
• Seven-byte data from FS to yH is processed as command data, but not as a part of
image data.
• When the amount of data exceeds the capacity left in the range defined by xL, xH, yL,
yH, the printer processes the data range specified by xL, xH, yL, yH.
• In the first group of NV bitmaps, when any of the parameters xL, xH, yL, yH is out of the
definition range, this command is disabled.
• When many bitmaps are downloaded, in case that XL, xH, yL, yH exceed the defined
range, the printer stops executing this command. The bitmap after that is ineffective
and the bitmap before is effective.
• The d indicates the definition data. In data (d) a 1 bit specifies a dot to be printed and a 0
bit specifies a dot not to be printed.
• This command defines n pieces of NV bitmap, of which the series number increases
from 1 in order. Therefore the first data group [xL xH yL yH d1...dk] is the data of NV
bitmap 1, and the last data group [xL xH yL yH d1...dk] is the data of NV bitmap n. The
bitmap printed by FS p is also same.
• A definition data of a NV bitmap consists of [xL xH yL yH d1...dk]. Therefore, when only
one NV bitmap is defined n=1, the printer processes a data group [xL xH yL yH d1...dk]
once. The printer uses ([data: ( xL + xH × 256) × ( yL + yH× 256) × 8] + [header:4])
bytes of NV memory.
• During the processing of this command, the printer is not tansmit status and not execut
status inquiry.
• Once a NV bitmap is defined, it is not erased by performing ESC @, reset, and power
off.
• This command performs only definition of a NV bitmap and does not perform printing.
Printing of the NV bitmap is performed by the FS p command.
• Define the relation between bitmap and bitmap data shown as below：

• During the processing of this command, the printer is in busy status. Because the data
now is being inputted into NV memory at that moment, the printer stops receiving other
commands. Hence during this command operation, other commands are not allowed to
be sent to the printer.

[Description] Choose paper mode and cut paper
Choosing paper mode according to m as follows:
m Cutting mode
0, 48 cut
1, 49 Half cut
65, 66 the distance from printing position to tear-off bar + n x 0.176mm
[Note , ] ①② • This command is effective at the beginning of line.
• Under marked paper mode, the cutting distance set by n is ineffective, printer will
mark before cutting.
[Note ] ① • Printer cut directly when m=0,48,1,49
• Printer cut after feeding the distance from printing position to tear-off bar + n x
0.176mm when m=65,66

3 Programming Process Guide
Because the different printing status and error can be transmitted by Auto Status Back (ASB)
command, it is recommended that you can use ASB command to inquiry status. ASB command is
effective when power on the printer and can be directly sent to inquiry the status.
The recommended programming process is shown as below:
1) Inquiry the printer status
Make sure that the printer status is normal before sending data to print.
2) Intitialize the printer
Make sure that the previous setting does not affect the current printing.
3) Setup the print content
Setup the print content such as character property, bitmap property and barcode property etc for the
needed printing effect.
4) Send the data for printing (including the setup command before printing)
If the printing data is bitmap data, please do not send the status inquiry command before sending
printing data.
5) Inquiry the printer status after printing
If ASB is enabled, the printer will return the printer status automatically.
