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. Hopefully, it can help
the programmers to get known of those commands.
1.1 Command classification
The commands of this receipt printer are classified as below:
Print commands: used for printing and feeding paper;
Position commands: to control the print position;
Character commands: to set character property;
Bitmap commands: to download and print bitmaps, 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, Macro-definition and initialization, etc.;
For command description, please refer to the detailed function of relative commands.
1.2 Key terms
Immediate 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 stores all data in a specified memory and thinks
of this as a virtual page. The page is printed only 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 and feeds paper upon printer line buffer full (data is
enough for one print line) or receiving print command like LF;
HRI character: Barcode note character.
NV memory: Non-volatile memory in which data stored does not lose when power-down.
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 printer. Example, 203DPI means 203 print dots per inch. DPI:
Dot Per Inch
Baseline: The standard position where character data in print buffers are stored. The
figure below shows the position of ordinary characters in standard mode and
page mode:

[Notes] • If this command is input in standard mode, the printer executes only internal flag
operation. This command does not affect printing in standard mode.
• If the horizontal or vertical starting position is set outside the print area, the printer
stops command processing and processes the following data as normal data.
• If the print area width or height is set to 0, the printer stops command processing and
processes the following data as normal data.
• This command and ESC T together set the current print position.
• If (horizontal starting position + print area width) exceeds the printable area, the
printable width is automatically set to (horizontal width －horizontal starting
position).
• If (vertical starting position + print area height) exceeds the printable area, the
printing height is automatically set to (vertical printable height – vertical starting
position).
• The horizontal and vertical motion units are specified by GS P. Changing horizontal
or vertical motion unit does not affect the current print area.
• Use the horizontal motion unit (x) to set the horizontal starting position and area width,
and use the vertical motion unit (y) to set the vertical starting position and area
height.

• 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 direction and starting position of the print area:
①When the starting position is set to the upper left or lower right of the print area
using ESC T, the horizontal motion unit is used.
②When the starting position is set to the upper right or lower left of the print area
using ESC T, the vertical motion unit is used;

Decimal 29 36 nL nH
[Range] 0 ≤nL ≤255, 0 ≤nH ≤255
[Notes] • This command is enabled only in page mode.
• If the [(nL + nH × 256) × (vertical or horizontal motion unit)] exceeds the specified
print area, this command is ignored.
• The horizontal position does not move after executing this command.
• The positions of relative commands are specified by ESC T
• Depending on the print area direction and starting position specified by ESC T, this
command operates as following:
①When the starting position is set to the upper left or lower right, this command sets
the absolute position in the direction which is parallel to the paper feed direction.
②When the starting position is set to the upper right or lower left, this command sets
the absolute position in the direction which is perpendicular to the paper feed
direction.
• The horizontal and vertical motion units are specified by GS P.
