1.2Command Notation
Real-time commands:
These commands are acted on immediately upon being received by the printer.
Page mode:
Under this mode, the printer stores all data in storage and thinks it as a virtual
page.The printer doesn’t print the page until it receives commands 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 when printer line buffer is full,namely data is
enough for one print line or it receives command like LF.
HRI character:
Bar code comment character.HRI:Human Readable Interface.
NV storage0:
Non-volatile storage which feature is stored data does not loss when the power is
turned off..
RAM:
Random Access Memory.
ASB：Auto Send Back.
DPI:
Print dots per inch (one inch equals to 25.4mm).It is used to identify the resolution of
the printer.For example,203DPI means it can print 203 dots per inch.
DPI:Dot Per Inch
[Name]
The name of the command.
[Format]
The format of the command,such as ASCII,Hexadacimal,Decimalism,etc.
[Range]
It gives the range of parameter which is used in commands.
[Default]
It gives the default values.
[Description]
It describes the function of the command.
[Notes]
It provides important information on setting and using the printer command.

[Description]
Prints the data in the print buffer and feeds one line.
[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.

[Description]
If the type of paper is continuous paper,feed paper in 20mm.
If the type of paper is A4,paper is out of printer.
[Notes]
This command is mainly used in the end of printing to separate the papers.

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.
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.
[Reference]
ESC D

[Notes]
When characters are enlarged, the character spacing is n times normal value.
This command sets values independently in each mode (standard and page
modes).

ESC ! n
Hex
1B 21 n

[Description] Select print mode(s) using n as follows:
[Notes]
When both double-height and double-width modes are selected,characters will
magnify two times in horizontal and vertical.
The printer can underline all characters,except the space set by HT,90clockwise
rotated characters and HRI characters..
All characters align at bottom.
ESC E can also turn on or off emphasized mode. However, the setting of the last
received command is effective.
ESC can also turn on or off underline mode. However, the setting of the last
received command is effective.
GS ! can also select character size. However, the setting of the last received
command is effective.

[(nL + nH ×256) ×0.125 mm].
[Notes]
This command is ignored when the setting position is outside of prnting area.
ESC W can set horizontal starting position in page modes. However, the setting of
the last received command is effective.

[Note]
If the value of m out of the specified range, nL and the subsequent data will be
processed as normal one.
The number of horizontal direction is up to nL and nH, the total number is nL + nH ×
256.
The part which bit-image is beyond the current area will be amputated.
d indicates the bit image data. Set a bit to 1 to print a dot, or set a bit to 0 to not
print a dot.
After the bit-image is sent successfully, the printer will be back to the normal data
processing mode.
If the width printing area set by GSL and GSW lee than the printing width of GS /
required by the data sent with the ESC* command, the following will be
performed 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.
This command won't be influenced by other print modes (emphasized /double-strike
/underline /characters amplification /white / black reverse), except upside-down
printing mode.

[Note]
This command is effective for all characters (including the blank space), but not the

blank space set by HT.
When underline mode is on, 90°clock wise rotated characters and characters and
white / black reverse characters cannot be underline.
When underline mode is off, there is no underline for following characters.
Underline width stays the same, default width: one dot width.
Character size change has no effects on underline width.
Turn underline mode on / off can be set by ESC !, the command executed at last is
effective.

[Notes] The bit image has been downloaded and custom characters in RAM is not cleared.
When the printer default is label paper, the print mode is page mode after power-
on.
When the printer default is continuous paper, the print mode is standard mode after
power-on.

n specifies the column number for setting a horizontal tab position from the
beginning of the line.
k indicates the total number of horizontal tab positions to be set.
[Notes]
The horizontal tab position is stored as a value of [character width ×n]
measured from the beginning of the line. The character width includes the
right-side character spacing, 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.
Up to 32 tab positions (k = 32) can be set. Data exceeding 32 tab positions is
processed as normal data.
Transmit [n]k in ascending order and place a NUL code 0 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.
The previously specified horizontal tab positions do not change, even if the
character width changes.
The character width is memorized for each standard and page mode.
[Default]
The default tab positions are at intervals of 8 characters (columns 9, 17, 25,...) for
Font A (12 ×24).
