GS $ nL nH
[Function]
[Code]
Specifying the absolute vertical position of characters in
PAGE MODE
HH
[Range] 0 nL 255
0 nH 255
[Outline]
[Caution]
This command is used in PAGE MODE to specify the vertical
position of characters at the data mapping start position as an
absolute value measured from the start point. The vertical
position of a character at the next data mapping start position
will be at a point [(nL + nH × 256) × basic calculation pitch] inches
away from the start point.
• This command is ignored when PAGE MODE is not selected.
• Any specification of absolute vertical position out of the print
area is ignored.
• The horizontal position of a character at the data mapping start
position is not moved.
• The start point used as the reference is specified by ESC T.
• Depending on the start point specified by ESC T, this command
acts as follows:
(1) If the start point is the top left or bottom right, the command
specifies the absolute position in the paper feed direction
(The character’s top-bottom direction), using the vertical
basic calculation pitch (y).
(2) If the start point is the top right or bottom left, the command
specifies the absolute position in the direction
perpendicular to the paper feed (The character’s top-bottom
direction) using the horizontal basic calculation pitch (x).
• The basic calculation pitch is set by GS P.
• Fractions resulting from calculations are corrected with the
minimum pitch of the mechanism, and the remainder is
omitted.
