It's close but as you can see no cigar. We looked into this early on
and (I) decided it wasn't very attractive because there was no way to
extract anything printable from the Graphics implementation to send
to the printer. But if you just want to print plain text (or trival
PostScript) this is doable and would probably not even be that much
code. Unfortunately it undoubtedly means breaking out Ethereal and
capturing a few print jobs to see what needs to be done. I'm very busy
at the moment with other things and jCIFS is stable right now so I
don't think I'll get around to this soon but I'll put it in docs/todo
(if it isn't already). If you are savvy enought to get a capture I'll
look at. Maybe it's trivial. Donno.
