Hmm, this is fairly easy. Just get a decent printer filter. I can print
a dvi file and the filter invokes dvips automatically. I can print ps
and the filter leaves it like this. It should be easy to add this additional
functionality.
PS files always start with !#PS, so you can recognize them quite easy.

Can`t remember offhand, but try man printcap or man termcap.
