On the Mac,
It isn't too hard to send raw postscript to a printer, especially
within a regular print job (It is actually difficult to do it
outside a regular print loop). My impression is that this isn't 
uncommon. And, indeed, it doesn't work with non postscript printers,
but sometimes the tradeoff is necessary. Like, before QuickdrawGX,
rotating text was a pain, but very easy with Potscript (I believe).

I doubt the IIGS LaserWriter drivers works this way. It doesn't
image at 300 dpi then dump the bitmap (Postscript does of course
support bitmaps); it translates the Quickdraw calls to roughly
equivalent Postscript code.
