1. Overview
1.1 Key terms
Real-time commands:These commands are act ed on immediately upon being received by the printer ;
Page mode:Under this mode, the printer stores all data in a specified memory and thinks of this as a virtual page.
The page is printed when the printer receives print command either FF or ESC FF;
Standard mode:Standard mode is the default mode of printer, namely line mode. Under this mode, the printer
prints data and feeds paper upon print line buffer full (data is enough for one print line) or receiving print
command like LF;
HRI character:Barcode note character. Human Readable Interface;
NV:Non-volatile memory in which data stored does not loss when powered off. NV: Non- volatile;
RAM :Random Access Memory;
ASB：Auto Send Back
DPI: Print dots per inch (one inch equals to 25.4mm). It is us ed to identify the resolution of a printer.
Example, 203DPI means 203 print dots per inch. DPI: Dot Per Inch
1.2 Command notation
[Name] The name of the command.
[Format] The code sequence.
[ ]k indicates the contents in brackets [ ] should be repeated k times.
[Range] Gives the allowable ranges, if any, for the command parameters.
[Default] Gives the default values, if any, for the arguments.
[Description] Describes the function of the command.
” − “ in the table indicates 0 or 1.

2. Printing command set
HT
[Name] Horizontal tab
[Format] ASCII HT
Hex 09
Decimal 9
[Dscription] Moves the print position to the next horizontal tab position.
[Notes] • 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.
• Set Horizontal tab default to 8 character width of character ASCII (12×24).
• When the print buffer is full，the printer performs the following actions：
In standard mode，the printer prints the current line and sets the print position to
the beginning of the line.
In page mode, the printer sets the print position to the beginning of the line.
LF
[Name] Print the contents in the print buffer
[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
[Notes] • This command sets the print position to the beginning of the line.
•When this command is processed in page mode, only the print position moves, and
the printer does not perform actual printing.
FF
[Name] Print and feed the paper to the next page
[Format] ASCII FF
Hex OC
Decimal 12
[Description ] Paper type is continuous paper :
• In page mode, prints all the data in the print buffer collectively and switches from
page mode to standard mode.
• This command is equivalent to LF in standard mode.
• This command returns the values set by ESC W to the default values.
Paper type is marked paper :
• In page mode, prints all the data in the print buffer,not to return to standard
mode ,not clear the data in the print buffer. The printer feeds the marked paper to
the next print starting position after finished printing.Don’t change horizontal and
vertical coordinates in the print buffer.
[Notes] • This command sets the print position to the beginning of the line.

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 ¬ does not provide sufficient width for the data, the left margin is reduced to
accommodate the data. For each bit of data in single-density mode (m = 0, 32), the
printer prints two dots: for each bit of data in double-density mode (m = 1, 33), the
printer prints one dot. This must be considered in calculating the amount of data
that can be printed in one line.
• It back to the normal data processing mode after printing a bit-image.

[Description] Prints the data in the print buffer and feeds the paper [n×0.125 mm (0.0049”)].
[Notes] 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
2or ESC 3.
•The maximum paper feed amount is 900 mm. If the paper feed amount (n × line
spacing) of more than 900 mm is specified, the printer feeds the paper only 900 mm .

Hex 1B 57 xL xH yL yH dxL dxH dyL dyH
Decimal 27 87 xL xH yL yH dxL dxH dyL dyH
[Range] 0 ≤ xL, xH, yL, yH, dxL, dxH, dyL, dyH ≤ 255
(except for dxL= dxH=0 or dyL= dyH=0)
[Description] Set the size and position of the printing area in page mode as follows:
Horizontal starting position: x0= [( xL + xH × 256) × 0.125mm]
Vertical starting position: y0 = [( yL + yH × 256) × 0.125mm]
Printing area width: dx = [ (dxL + dxH × 256) ×0.125mm]
Printing area height: dy = [ (dyL + dyH × 256) ×0.125mm]
[Note] •This command is processed in standard mode to set an activated internal flag so that
don't influence printing.
• The printer stop processing this command once horizontal starting position or vertical
starting position ran out of the printing area, the subsequent data are processed as
normal one.
• The printer stop processing this command once printing area width or height was set
to 0, the subsequent data are processed as normal one.
• This command confirms the current printing position with command ESC T.
•The default set of printing area width is horizontal printable width - horizontal starting
position if the value of horizontal starting position + printing area width was beyond
printable area.
• The default set of printing area height is vertical printable height - vertical starting
position if the value of vertical starting position + printing area height was beyond
printable area.
• The default settings of the horizontal and vertical motion units are 0.125mm.
•Assuming horizontal starting position, vertical starting position, printing area width and
printing area height X, Y, Dx, Dy, set the printing area as shown below:
[Default] xL = xH = yL = yH = 0
dxL, dxH, dyL and dyH decided by printer settings

[Format] ASCII ESC \ nL nH
Hex 1B 5C nL nH
Decimal 27 92 nL nH
[Range] 0 ≤ nl ≤ 255 0 ≤ nH ≤ 255
[Description] Sets the relative horizontal print starting position from the current position.
This command sets the distance from the current position to [(nL + nH × 256)×
0.125 mm (0.0049”)].
[Notes] •The printer ignores any setting that exceeds the print area.
• When pitch N is specified for the movement to the right：nL+ nH × 256 = N。
• Use the complement of N for setting N pitch movement to the left: (nL + nH × 256) =
65536 – N.
• Print starting position from the current position to [N × 0.125mm].
