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 B 0C).

Formulas

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 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.
