[Caution] •This command works for all alphanumeric characters except for HRI characters.
•This command is ignored if either the vertical magnification or horizontal
magnification is out of range.
•In Standard mode, the vertical direction is defined as the paper feed direction,
and the horizontal direction is defined as the direction perpendicular to the
paper feed. These definitions are, therefore, interchanged when 90
°
-right-
turned characters are specified.
•In Page mode, the vertical direction means the top-bottom direction of each
character. The horizontal direction means the side-to-side direction of each
character.
