Explanation (1) n is valid only in the least significant bit.
(2) Reversed printing applies to the internal and downloaded characters.
(3) Reversed printing also applies to spacing on the right of a character defined by the
Spacing Set Command ([ESC] [SP]).
(4) There is no impact upon bit images, downloaded bit images, barcodes, or HRI
characters, or a portion skipped by the Horizontal Tab Command ([HT]) or Relative
Position Set Command ([ESC] \).
(5) There is no impact upon spacing between lines.
(6) A higher priority is given to reversed printing than underlining. Therefore, even if
underlining is specified, reverse characters will not be underlined. However, the
underlining settings will remain unchanged.
