Sets the relative vertical print starting position from the current position. This
command can also change the horizontal and vertical motion unit. The unit of
horizontal and vertical motion is specified by this command.
This command functions as follows, depending on the print starting position set
by Select Print Direction in Page Mode (1B 54):
1. When the starting position is set to the upper left or lower left of the printing
area, the vertical motion unit (
y
) is used.
2. When the starting position is set to the upper right or lower left of the
printing area, the horizontal motion unit (
x)
is used.
Value:
The value for the horizontal and vertical movement cannot be less than the
minimum horizontal movement amount, and must be in even units of the
minimum horizontal movement amount.
Formulas:
The distance from the current position is set to [(
nL
+
nH
x 256) x vertical or
horizontal motion unit] inches. The amount of movement is calculated only for
the receipt.
When pitch
n
is specified to the movement downward:
nL + nH
x 256 =
n
When pitch
n
is specified to the movement upward (the negative direction), use
the complement of 65536.
When pitch
n
is specified to the movement upward:
nL
+
nH
x 256 – 65536 –
N
Exceptions:
This command is used only in Page Mode, otherwise it is ignored.
Any setting that exceeds the specified printing area is ignored.
