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.
