I've also had these problems with 5.0 and had to back to slackware.
The problem is that when the remote print job arrives at the print
server the server runs it through the redhat print-filter system.
It uses ghostscript to do this. Unfortunately it tries to run
ghostscript as the user who submitted the remote print request. If
this user is not in the local password file or available through
YP then it can't fork the ghostscript process ( see above ) and
nothing gets printed.
I haven't got a workaround for this yet.
