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).
