Barring that, PostScript would even be a decent
alternative to PDF -
 it's fairly readable Forth, and any decent printer can accept it to
 produce a new hardcopy. 
Based on my rather limited understanding, PDF more or less *is*
PostScript - they're similar at a fairly high level - both stack
languages based on approximately the same imaging model....
  (Yes, I'm saying if a printer can't be made to
accept postscript -
 either standard or via an option ROM, it isn't "decent".) 
Feh.  I'd much rather have something like a SPARCprinter that just
takes page bitmaps from the host.  It's easy to generate bitmaps with
something like GhostScript, but convincing a PostScript printer to just
print a page bitmap is..a struggle.
