The default value of n is 1. For more information see “ Page Mode” later in this
section.
Note: Only the lowest bit of n is effective. When n is even, uni-directional
printing is turned off and when n is odd, uni-directional printing is
turned on.

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 Fundamental
Calculation Pitch 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)]
