[Samba] Print jobs hang in Samba, don't go to UNIX spooler

[Windsor Dave (AdW/MOE2.1)]

I'm running the lp spooling system that comes with
HP-UX.  I don't think that the spooler itself is a
problem, as I have no trouble printing from a shell
prompt.  The lp command in the print command does not
point to a symlink, but I'll try it with an absolute
path, just in case.  However, since the "echo" isn't
being performed either, it looks like the print command
isn't being executed at all.  Here's what my print
command looks like. taken almost directly from an example
in the smb.conf man page:

print command = echo Printing %s on %p >>/tmp/print.log; lp -c -d%p %s; rm
%s

Nothing ever appears in /tmp/print.log.  The weird thing
is that all was fine until yesterday afternoon, when
printing just......stopped.  No changes were made on the
system to either Samba or the lp spooler.

Best regards,

what are you running for the printer daemon?

If you're running lprng,
does "checkpc -V -f >/tmp/dump" show
anything useful when you read /tmp/dump?

Look to see if the print command=
entry has the explicit path to the
spooler-if it points to a symbolic link,
and the link has been broken, spooled
jobs won't print.  That's happened to me
after upgrading my OpenBSD-it reinstalls
lpd, etc, and LPRng is broken and needs
to be reinstalled.

Good luck,
  Jim
