Why is printing slower on Panther?
OzTeX 5.1 on Panther fails to detect if your current printer supports PostScript, so it doesn’t call dvips but uses a slow bitmap printing method. In OzTeX 5.2 the “Force PostScript Printing” flag is always ticked on Panther or later and so OzTeX always calls dvips. This is possible because Gimp-Print (which comes installed with Panther) allows PostScript data to be sent to a non-PostScript printer.
