Select or cancel white/black reverse print mode
ASCII
Hexadecimal
Decimal
GS B n
1D 42 n
29 66 n
Value of n:
0 = Off
1 = On
(When 0 and 1 are the least
significant bit, LSB)
Range of n:
0-255
Default:
0 (Off )
White/black reverse print mode has a higher priority than
underline mode. When underline mode is on and white/
black reverse print mode is selected, underline mode is
disabled, but not canceled.
Bar codes, logos, and bit images are not affected by this
command.
Turns on white/black reverse print mode. In white/black
reverse print mode, print dots and non-print dots are
reversed, which means that white characters are printed
on a black background. When the white/black reverse print
mode is selected it is also applied to character spacing
which is set by right-side character spacing (1B 20).
Exceptions
This command can be used with built-in characters and
user-defined characters, but does not affect the space
between lines.
In A793 emulation, the command is unrecognized and the
parameter byte is put into the print buffer.
Only the lowest bit of n is valid.
Related information
If the current color is not black and 2-color paper is
loaded, no visible effect takes place.
White/black reverse print mode does not affect bit image,
downloaded bit image, bar code, HRI characters, and
spacing skipped by horizontal tab (09), set absolute
starting position (1B 24 …), and set relative print
position (1B 5C).
Select or cancel smoothing mode
ASCII
Hexadecimal
Decimal
GS b n
1D 62 n
29 98 n
Value of n
Hex. 30 smoothing disabled
Value of m
Hex. 31 smoothing enabled
Effects of smoothing are most effective on large
charactors, (Select character size command 1D 21 xx.)
Reverse color text mode (ColorPOS™)
ASCII
Hexadecimal
Decimal
GS 0x85 m n
1D 85 m n
29 133 m n
Value of m:
0 = white
1 = black
2 = paper color
Value of n:
0 = white
1 = black
2 = paper color
Default:
m = 0 (off )
Sets a mode for reverse printing effects on text. The
background color is specified by m, while the text color is
specified by n. Setting m = 0 turns off the mode.
If m = n but not zero, the printer produces solid printing in
the given color. This tactic can be used to minimize the
firmware busy work.
The value of current color and white/black reserve print
mode is superceded by the value of n whenever this mode
is on (m>0).
Bar codes, logos, and bit images are not affected by this
command.
