This keyword specifies the maximum possible size of the plotting window, in inches. This will attempt to make the window as large as possible on the page, leaving only a 0.25-inch margin around the edge. The reason is that on most printers, forcing it to print more pixels along an axis exceeds the printer resolution and results in poor halftone color rendering. DH is the horizontal offset, and DV is the vertical offset. Note that which is horizontal or vertical depends on whether or not the LAND keyword was used.
Considerable experimentation is needed to find the right level.
