Non-PostScript scaling errors

Before starts non-PostScript printing, it checks to see that the printer resolution parameter matches the actual resolution of your printer. If the resolutions don't match then will warn you that scaling problems may occur. This warning appears just before the print dialog in case you want to Cancel printing (you might have forgotten to switch to the correct configuration file). If you decide to go ahead and print the DVI file, you might see problems such as horizontal gaps at regular intervals down each page. prints a page by sending a sequence of horizontal bands to the printer. The number of bands depends on how much memory is available (the band height is displayed when showing statistics). Scaling problems can result in gaps or overlapping at band boundaries, but they can be avoided by bumping up 's memory to a suitably large value so that only one large band is needed to print each page.
