ELECT OR CANCEL WHITE/BLACK REVERSE PRINT MODE
Turns on White/Black reverse printing mode. In White/Black reverse printing 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 printing mode is selected it is also applied to character spacing which is set by Right-
Side Character Spacing (ESC SP).
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 (HT), Set Absolute Starting Position (ESC $), and Set
Relative Print Position (ESC \).
