Hex 1D 42 n

Decimal 29 66 n

[Range ] 0 ≤≤n ≤255

of n is 0, white / black reverse mode is turned off. When the LSB of n is 1, white /

black reverse mode is turned on.

[Notes ]

In white /black reverse printing mode, print dots and non-print dots are reversed.

(Characters are printed in white on a black background.) This command is

available for built-in characters and user-defined characters. When white /black

reverse printing mode is on, it also applied to character spacing set by ESC SP.

This command does not affect bit image, downloaded bit image, bar code, HRI

characters, and spacing skipped by HT,ESC $,and ESC ＼. This command does

not affect the space between lines. White /black reverse mode has a higher

priority than underline mode. Even if underline mode is on,

it is disabled (but not canceled) when white / black reverse mode is selected.
