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.
