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.
Exceptions
Only the lowest bit of n is valid.
