GS \ nL nH
[Function] Specifying the relative vertical position of a character in PAGE MODE
[Code] <1D>H<5C>H<nL><nH>
[Range] 0 nL 255
0 nH 255
[Outline] This command is used in PAGE MODE to specify the vertical position of a character
in the data mapping start position, in a relative position with respect to the current
position. The next data mapping start position will be at a point [(nL + nH × 256) ×
basic calculation pitch] inches away from the current position.
[Caution] • This command is ignored when PAGE MODE is not selected.
• If a new position is specified for a character located beneath the current position, it
should be specified as positive (+). If it is above the current position, it should be
negative (–).
• A negative value is the complement of 65536. For example, to move the position
by N pitches up, specify it as:
nL + nH × 256 = 65536 – N
• The specification of a relative position outside the specified print area is ignored.
• 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
relative 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
relative 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.
