GS \ nL nH
[Designation] Set relative position for character direction in page mode
[Format] 1DH, 5CH, 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 relative to the current point, which is the
origin.
(2) The position moved [(nL+nH×256)×basic calculated pitch] inches from the
current position is the next data expansion start position.
(3) This command is ignored if page mode is not selected.
(4) If a position in the downward direction from the current position is specified for
a character, a positive numbers (plus) will result. If a position in the upward
direction is specified, a negative number (minus) will result.
(5) Negative numbers are displayed as complements of 65536.
For example, for N-pitch movement upward,
nL+nH×256=65536 - N.
(6) Relative print positions that exceed the specified print area are ignored.
(7) The operations given below are executed by 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
relative 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
relative 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.
(10) For JIS notation characters, the \ symbol is equivalent to the symbol.
