This command is effective for all characters (except for
HRI characters).
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.
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 standard mode, the vertical direction is limited to 7
(seven times height) when Tall or ColorPOS™ font is
selected. If 8 (eight times height) is selected, the
application will fall back to the setting of 7 (seven
times height).

In A793 emulation, this command is discarded and not put
into print buffer.
