Set Absolute Vertical Print Position in Page Mode
ASCII : GS $ nL nH
Hexadecimal : 1D 24 nL nH
Decimal: 29 36 nL nH
Formulas:
[( nL + nH X 256) x (vertical or horizontal motion unit)] inches.
Sets the absolute vertical print starting position for buffer character
data in
Page Mode.
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 direction 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.
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.
