[Outline] This command specifies or cancels the black/white inverted printing.
•If n = <*******0>B, the black/white inverted printing is canceled.
•If n = <*******1>B, the black/white inverted printing is specified.
[Caution] •Number "n" is only valid in the lowest bit.
•The black/white inversion works on internal and downloaded characters.
•The black/white inversion works also on the right spacing of characters defined
by ESP SP.
•This command does not affect the bit image, downloaded bit image, bar code,
HRI characters, or the skip area specified by HT, ESC $, or ESC ¥.
•This command does not affect the space between lines.
• Black/white inversion specification take precedence over underline
specification. Underline printing due to underline specification is, therefore,
nullified if black/white inversion is specified; the underline setting, however,
remains unchanged.
[Default] n = 0
