The maximum printable area of a LaserWriter is 6.75 x 13.0 inches when
centered on an 8.5 x 14 inch page.
The LaserWriter II engine has a minimum left, right, top, and bottom margin
of 0.197 inches. This gives the LaserWriter II a printable area of 8.106 x
13.606 inches. So, the only way to get a larger print area is to use a
LaserWriter II series printer.
