Set Print Area in Page Mode
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(FF or ESC FF).
ASCII ESC W n1, n2 ...n8.]
Hexadecimal 1B 57 n1, n2 ...n8]
Decimal 27 87 n1,n2 ...n8]
Range of n 0-255
Default n1-4 = 0

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.
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).
♦
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.
