This command is effective to all characters (alphanumeric and Kanji) except
for HRI characters.
If n is outside of the defined range, this command will be ignored.
In standard mode, the vertical direction is the paper feed direction, and the
horizontal direction is perpendicular to the paper feed direction. However,
when character orientation changes in 90° clockwise-rotation, the relationship
between vertical and horizontal directions is reversed.
In page mode, vertical and horizontal directions are based on the character
orientation.
When characters are enlarged with different sizes on one line, all the
characters on the line are aligned at the baseline.
The ESC ! command can also turn double-width and double-height modes on
or off. However, the setting of the last received command is effective.
[Default] n = 0
[Relative] ESC !
[Demo] Refers to ESC !
GS B n
[Function] Turn white/black reverse printing mode
[Format] ASCII GS B n
Hex 1D 42 n
Decimal 29 66 n
[Range] 0 ≤ n ≤ 255
[Notes] Turns on or off white/black reverse printing mode.
· When the LSB 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] · Only the lowest bit of n is valid.
·This command is effective to all characters (alphanumeric and Kanji) except
for HRI 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, user-defined bit image, bar code,
HRI characters, and spacing set 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.
[Default] n = 0
