Maximum area specification in page mode
Maximizing the possible area in page mode consumes almost all of free RAM. Without any free RAM, bitmap rotations
and enlargements cannot be performed. Use the user storage status command (1D 97 m n) to determine the amount
of free memory.
Exceptions
The command is effective only in page mode.
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 Ч 256) Ч (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 Ч 256) Ч (vertical or horizontal motion unit)] inches.
Exceptions
This command is effective only in page mode.
If the [(nL + nH Ч 256) Ч (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.
