A798-PG00001C
Select or cancel white/black reverse print mode
ASCII GS B n
Hexadecimal 1D 42 n
Decimal 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)
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).
This command can be used with built-in characters and user-defined characters, but does not affect the space between
lines.
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).
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.
Exceptions
Only the lowest bit of n is valid.
