A776 (B780) Programming Guide 

A776-PG00001 C 12/09

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.

This command is only valid for the receipt station.

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The value of current color and white/black reserve print mode is superseded by the value of n whenever this mode is 
on (m>0).  Bar codes, logos, and bit images are not affected by this command.
