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 label 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 and RAM bitmap;
Status commands: used for printer status query;
Barcode commands: barcode print and property settings;
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;
Page mode –Under this mode, the printer possesses all data in 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 – Human Readable Interface;
NV – Non-volatile memory in which data stored does not loss when power off. NV: Non-volatile
RAM –Random Access Memory;
DPI – Print dots per inch (one inch equals to 25.4mm). It is used to identify the resolution of a printer.
Example, 203DPI means 203 print dots per inch.
Baseline – The standard position where character data in print buffers are stored. The figure shows
the position of ordinary characters in standard mode and page mode:

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;
[Example] 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.

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.

· Parameters for horizontal or vertical motion units (x or y) differ as follows, depending on
the starting position of the printing area:
1) If the starting position is the upper left or lower right of the printing area, data is
buffered in the direction perpendicular to the paper feed direction:

the horizontal starting position, vertical starting position, printing area width, and printing
area height are defined as x0、y0、dx、dy setting for the printing area is calculated as
follows:
x0 = [( xL + xH × 256) × (horizontal motion unit)]

stops command processing and processes the following data as normal data.
· If the printing area width or height is set to 0, the printer stops command processing and
processes the following data as normal data.
· This command sets the position where data is buffered to the position specified by ESC
T within the printing area.

· The horizontal and vertical motion units are specified by GS P.
· In standard mode, the horizontal motion unit is used.
· In page mode, the horizontal or vertical motion unit differs as follows, depending on the
starting point of the printing area:
1) When the starting position is set to the upper left or lower right of the printable area
using ESC T, the horizontal motion unit (x) is used.
2) When the starting position is set to the upper right or lower left of the printable area
using ESC T, the vertical motion unit (y) is used.

n selects the justification as follows：
n Justification
Left justification
Centering
Right justification
[Notes] • This command is enable only when processed at the beginning of the
line in the standard mode.
• If this command is input in page mode, the printer performs only internal flag
operations.
• This command justifies the space area according to HT, ESC $ or ESC\.

GS $ nL nH
[Function] This command sets the absolute print position to [( nL + nH × 256) ×
(vertical or horizontal motion unit)] inches.
[Format] ASCII GS $ nL nH
Hex 1D 24 nL nH
Decimal 29 36 nL nH
[Range] 0 ≤nL ≤255, 0 ≤nH ≤255
[Notes] • This command is effective only in page mode.
• If the [( nL + nH × 256) × (vertical or horizontal motion unit)] exceeds the specified
printing area, this command is ignored.
• The horizontal starting buffer position does not move after run this command.
Relative starting position is that specified by ESC T.
• This command operates as follows, depending on the starting position of the printing
area specified by ESC T：
1) When the starting position is set to the upper left or lower right, this command
sets the absolute position in the horizontal direction.
2) When the starting position is set to the upper right or lower left, this command
sets the absolute position in the vertical direction.
• The horizontal and vertical motion units are specified by GS P.

[Notes] • This command is effective only processed at the beginning of the line in
standard mode.
• If this command is input in page mode, this command is not effective and the printer
regard this command as normal character to dispose.

• This command does not affect printing in page mode.
• If the setting exceeds the printable area, the maximum value of the printable area is
used.
• The horizontal and vertical motion units are specified by GS P. Changing the
horizontal and vertical motion unit does not affect the current left margin.

GS P x y
[Function] Sets the horizontal and vertical motion units to approximately 25.4/ x mm
{ 1/ x inches} and approximately 25.4/ y mm {1/ y inches}, respectively.
[Format] ASCII GS P x y
Hex 1D 50 x y
Decimal 29 80 x y

[Notes] • When x and y are set to 0, the default setting of each value is used.
• The horizontal direction is perpendicular to the paper feed direction and the vertical
direction is the paper feed direction.
• In standard mode, the following commands use x or y, regardless of character
rotation (upside-down or 90° clockwise rotation):
1) Commands using x ：ESC SP, ESC $, ESC \, FS S, GS L, GS W
2) Commands using y：ESC 3, ESC J, GS V
• In page mode, the following command use x or y, depending on character
orientation:
1) When the print starting position is set to the upper left (Printing direction from left to
right)or lower right(Printing direction from right to left) of the printing area using ESC
