Set absolute vertical print position in page mode
ASCII GS $ nL nH
Hexadecimal 1D 24 nL nH
Decimal 29 36 nL nH
Sets the absolute vertical print starting position for buffer
character data in page mode. The absolute print position is
set to [(nL + nH X 256) x (vertical or horizontal motion
unit)] inches.
The vertical or horizontal motion unit for the paper roll is
used and the horizontal starting buffer position does not
move.
The reference starting position is set by select print
direction in page mode (1B 54). This sets the absolute
position in the vertical direction when the starting position
is set to the upper left or lower right; and sets the absolute
position in the horizontal when the starting position is set
to the upper right or lower left. The horizontal and vertical
motion unit are specified by the set horizontal and vertical
minimum motion units (1D 50) command.
The set horizontal and vertical minimum motion units
(1D 50) command can be used to change the horizontal
and vertical motion unit. However, the value cannot be
less than the minimum horizontal movement amount, and
it must be in even units of the minimum horizontal
movement amount.
Formulas
[(nL + nH X 256) x (vertical or horizontal motion unit)]
inches.
Exceptions
This command is effective only in page mode.
If the [(nL + nH X 256) x (vertical or horizontal motion
unit)] exceeds the specified printing area, this command is
ignored.
Set relative vertical print position in page mode
ASCII GS \ nL nH
Hexadecimal 1D 5C nL nH
Decimal 29 92 nL nH
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.
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.
1. This command functions as follows, depending on the
print starting position set by select print direction in
page mode (1B 54):
2. When the starting position is set to the upper right or
lower left of the printing area, the vertical motion unit
(y) is used.
3. When the starting position is set to the upper left or
lower right of the printing area, the horizontal motion
unit (x) is used.
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
paper roll.
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.
