GS $ nL nH
[Designation] Set absolute position for character direction in page mode
[Format] 1DH, 24H, nL, nH
[Valid limits] 0 nL 255
0 nH 255
[Initial value] ---
[Function] (1) Specifies the position of characters vertically at the data expansion start position
in page mode using the print position as the starting point, which is the
absolute position.
(2) The position moved [(nL+nH×256)×basic calculated pitch] inches from the
starting point is the position of the vertical character of the next data
expansion start position.
(3) This command is ignored if page mode is not selected.
(4) Absolute print positions that exceed the specified print area are ignored.
(5) The positions of horizontal characters of data expansion start positions are not
moved.
(6) The ESC T command is used to specify the starting point used for
reference.
(7) The operations given below are executed based on the starting point specified
using the Select print direction in page mode command (ESC T):
a. If the starting point has been specified as upper left or lower right, the
absolute print position in the paper feed direction is specified.
At this time, the vertical motion unit (y) is used.
b. If the starting point has been specified as upper right or lower left, the
absolute print position perpendicular to the paper feed direction is specified.
At this time, the horizontal motion unit (x) is used.
(8) The basic calculated pitch is set up using the Set horizontal and vertical motion
unit (GS P).
(9) If the calculation result contains a fraction, the value is corrected using the
minimum pitch of the mechanism. The remainder is then discarded.
