in the x direction is set to dx inches. Use the equations to determine the Value of x0, y0, dx, and
dy.

x0 = [( n 1 + n 2 x 256) x (horizontal direction of the fundamental calculation pitch)]

y0 = [( n 3 + n 4 x 256) x (vertical direction of the fundamental calculation pitch)]

dx = [( n 5 + n 6 x 256) x (horizontal direction of the fundamental calculation pitch)]

dy = [( n 7 + n 8 x 256) x (vertical direction of the fundamental calculation pitch)]
Keep the following notes in mind for this command.

The fundamental calculation pitch depends on the vertical or horizontal direction.

The maximum printable area in the x direction is 576/203 inches.

The maximum printable area in the y direction is 576/203 inches.
See the illustration for a graphic representation of the printing area. For more information about
the fundamental calculation pitch, see the set horizontal and vertical motion units command (1D
50).
Maximum area specification in page mode
Maximizing the possible area in page mode consumes almost all of the 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.
If [x0 + dx] is greater than the printable area, the printing area width is set to [horizontal printable
area – x0]. If [y0 + yx] is greater than the printable area, the printing area height is set to [vertical
printable area – y0].
Set absolute vertical print position in page mode
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.
