As I said, PostScript can do anything you want with bitmaps, including scaling and rotating them. The Apple LaserWriter implementation of PostScript can use any of the Macintosh screen fonts directly. You can download full-page rasters, 4-bit rasters, or anything in between. I can't imagine why anybody in their right mind would want to put Computer Modern fonts into a PostScript printer when it has real fonts. This is an aesthetic reason. There is certainly no technological reason why you cannot do this. Converting splines to rasters might or might not be slow (it's much faster than you think), but the PostScript printers all have font caches in them. The font cache in the Apple LaserWriter is bigger than the entire font memory in my Imagen 12/240 printer. If you have a cache you only have to do the conversion once. After you have printed a page or two in some font, all of the rasters are in the cache and the printer runs at full speed. I don't think you have a glimmer of an understanding of what a major-league printer the PostScript engines are, or you wouldn't even think about comparing them to, say, Symbolics printers. They are a completely new and different breed of printer and you really should not flame them out until you understand what they are, or better yet until you try one. Brian Reid Stanford
