Sets the position and size of the printing area in page
mode.
The command can be sent multiple times so that several
different print areas, aligned in different print directions,
can be developed in the printer’s page buffer before
being printed using the print page mode commands
(0C or 1B 0C).
Formulas
(x0, y0)
dx
(x0 + dx, y0 + dy)
dy
Print Area
y direction maximum
monochome = 1800
two-color =
900
The starting position of the print area is the upper left of
the area to be printed (x0, y0). The length of the area to be
printed in the y direction is set to dy inches. The length of
the area to be printed in the x direction is set to dx inches.
Use the equations to determine the Value of x0, y0, dx,
and dy.
•
x0 = [(n1 + n2 x 256) x (horizontal direction of the
fundamental calculation pitch)]
•
y0 = [(n3 + n4 x 256) x (vertical direction of the
fundamental calculation pitch)]
•
dx = [(n5 + n6 x 256) x (horizontal direction of the
fundamental calculation pitch)]
•
dy = [(n7 + n8 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 127 kBytes of free RAM. Without any
free RAM, bitmap rotations and enlargements cannot be
performed. The table below shows the maximum area in
page mode, limited by free RAM.
