Default:
n = 0
Description: Selects the character height (vertical number of times normal font size)
using bits 0 to 2 and selects the character width (horizontal number of
times normal font size) using bits 4 to 6, as follows:

Notes:
• The character size set by this command is effective for all characters
(except for HRI characters).
• When the characters are enlarged with different heights on one line, all
the characters on the line are aligned at the baseline.
• When the characters are enlarged width wise, the characters are
enlarged to the right, based on the left side of the character.
• ESC ! can also turn double-width and double-height modes on or off.
That means it overwrites the settings of GS !.
