[Caution] • This command is valid for all characters (alphanumeric, kana, and kanji) except for
HRI characters.
• This command is ignored if either the vertical magnification or horizontal
magnification is out of the defined 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.
• Setting memory SW 3-7 to ON allows the horizontal and vertical relations to be
interchanged when 90°-right-turnning of character is 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. If characters of different vertical magnification are contained in a line,
the baseline of each character is lined up.
• Horizontal and vertical magnification can also be specified/canceled by ESC ! but
the setting of command last processed is valid.
