Apple's laser prep file does load a chunk of 68000 object code into the
laser printer to do bitmap smoothing, and it does use a postscript
operator to do it \eexec (as I recall.) However, all the existing
PostScript interpeters use 68000s (or 68020s) and code licensed from Adobe.
(even the typesetters: the existing postscript compatible typesetters use
a front end postscript processor called a RIP.) So, the Apple bit
smoothing code works in them all. My wife typeset a children's book on a
LinoTronic 100 using the standard LaserWriter drivers and including some
macpaint pictures pasted into a MacDraw file. What with the smoothing,
and the LinoTronics 1200 bpi resolution, the pictures looked great.

Hint: paste a bitmap picture into macdraw, group it (to get around the 3k
limit on bitmap pieces) then shrink it by a factor of 4, and you've got
laser dots resolution bit map editing without having to buy superpaint and
without superpaint's one page size limit.
