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.
