This command is effective for all characters (except for HRI characters) and is effective until the
printer is initialized, reset, or powered off.
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
degree clockwise-rotation mode, 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. When characters are enlarged width- wise, the characters are enlarged to the right,
starting from the left side of the character.
The select print mode (1B 21
n ) command can also select or cancel double-width and double-
height modes. However, the setting of the last received command is effective.
Exceptions
If n is out of the defined range, this command is ignored.
In native mode, the vertical direction is limited to 7 (seven times height) when Tall font is selected.
If 8 (eight times height) is selected, the results are unspecified.

In A793 emulation, this command is discarded and not put into print buffer.
Select or cancel white/black reverse print mode
ASCII GS B n
Hexadecimal 1D 42 n
Decimal 29 66 n
Value of n : 0= Off
1 = On
Range of n : 0–255
Default: 0 (off)
Turns on white/black reverse print mode. In white/black reverse print mode, print dots and non-
print dots are reversed, which means that white characters are printed on a black background.
When the white/black reverse print mode is selected it is also applied to character spacing which is
set by right-side character spacing (1B 20).
This command can be used with built-in characters and user-defined characters, but does not
affect the space between lines.
White/black reverse print mode does not affect bit image, downloaded bit image, bar code, HRI
characters, and spacing skipped by horizontal tab (09), set absolute starting position (1B 24 …),
and set relative print position (1B 5C).
White/black reverse print mode has a higher priority than underline mode. When underline mode
is on and white/black reverse print mode is selected, underline mode is disabled, but not canceled.
Bar codes, logos, and bit images are not affected by this command.
Exceptions
Only the lowest bit of n is valid.
