A798-PG00001C
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.
This command functions as follows, depending on the print starting position set by select print direction in page mode
(1B 54):
When the starting position is set to the upper right or lower left of the printing area, the vertical motion unit (y) is used.
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.
