1 General Information
1.1 Key Terms
Real-time commands – These commands are acted on immediately upon being received by the printer.
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 memory– Non-volatile memory in which data stored does not loss when power off.
RAM –Random Access Memory
Motion unit –The motion unit has vertical motion unit and horizontal motion unit, which specify the least
space for vertical motion and horizontal motion.
ASB – Auto status back.
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. DPI: Dot Per Inch.

[Format] ASCII HT
Hex 09
Decimal 9
[Description] 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.
• The default setting of the horizontal tab position for the paper roll is font 0 (12×24) every
8th character.
• When the buffer of the line is full, the printer executes as follows:
In standard mode, the printer print the data of current line and set the printing position at
the beginning of next line.
In page mode, the printer shifts newline and sets the printing position at the beginning of
next line.

Hex 0A
Decimal 10
[Description] In standard mode, it prints the data in the print buffers and feeds one line based on the
current line spacing.
[Note] This command sets the print position at the beginning of the line.
In page mode, the printer shift newline and set the position at the beginning of Next line.
But it doesn’t execute the print.

· If the printing area set by GS L and GS W is less than the printing width needed by GS/,
the printer shall act as below quickly (but cannot exceed Max. printing width).
1) The printing area shall extend to the right for matching the printing bit image.
2) If step 1) cannot provide enough width for the data, the left margin shall be reduced to
match it. For each bit of the data in single density mode (m=0.32), the printer shall print
two dots; for each bit of the data in double density mode (m=1.33), the printer shall
print one dots. In calculating the printable data for each line, you must consider it.
· After printing a bit image, the printer shall return normal data processing mode.
· This command shall not be effected by other printing modes (such as emphasized,
double-strike, underline, character size, or white/black reverse printing) except
upside-down printing mode.
· The relation of the data and the dots to be printed is as below:

Hex 1B 44 n1...nk 00
Decimal 27 68 n1...nk 0
[Range] 1 ≤n ≤255

[Description] Sets horizontal tab positions.
· n specifies the column number for setting a horizontal tab position from the beginning of I
the line.
· k indicates the total number of horizontal tab positions to be set.
[Notes] · The horizontal tab position is calculated as follows:
Character width x n. The character width includes the right-side character spacing.
· This command cancels the previous horizontal tab settings.
· When setting n = 8, the print position is moved to column 9 .
· Up to 32 tab positions (k = 32) can be set. Data exceeding 32 tab positions is processed
as normal data.
· Arrange tab positions in ascending order and place a NUL at the end.
· When [n] k is less than or equal to the preceding value [n] k-1, tab setting is finished and
the following data is processed as normal data.
· ESC D NUL cancels all horizontal tab positions.
· Change character width, and previous tab positions specified is not changed.
· Character width is independent under standard mode and page mode.
[Default] The default tab positions are at intervals of 8 characters for font A (12 × 24).

[Range] 0 ≤n ≤255
[Description] Prints the data in the print buffer and feeds the paper [n × horizontal motion unit] inches.
[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 2 or ESC 3.
· In standard mode, the printer uses the vertical motion unit (y).
· In page mode, select vertical motion unit or horizontal motion unit according to the print
area direction and the beginning position of print in the way as below:
①When the starting position is set to the upper left or lower right of the
printable area using ESC T, the vertical motion unit (y) is used.
②When the starting position is set to the upper right or lower left of the printable area
using ESC T, the horizontal motion unit ( x) is used.
· The maximum feeding distance is 900mm (35.4 inches). When the setting value
exceeds the maximum, it is converted to the maximum automatically.
