[Caution] • The black/white inversion works on internal and downloaded characters.
• The black/white inversion works also on the right spacing of characters defined by
ESC 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 takes precedence over underline specification.
Underline printing specified is, therefore, nullified if black/white inversion is
specified; the underline setting, however, remains unchanged.
