samba - Aug 2002 - Print jobs hang in Samba, don't go to UNIX spooler

I have encountered a strange printing problem with Samba 2.2.4 running under

HP-UX 11i.

In the process of investigating a printing problem, I have found that Samba
has stopped passing jobs along to the UNIX lp spooler as of yesterday
afternoon.
When NT/W2K clients print to printers on my server, the jobs are accepted,
Samba
spool files are created in the spool directory defined for the printer (with
names such as smbprn.005594.a14088), but they never actually get printed.
The
UNIX spooler is working OK, since I can issue an "lp" command from a
shell
prompt and get a printout.  Printing was working fine until just after lunch
yesterday.  Nothing has changed in the Samba or system configuration of
which
I am aware.  Does anyone know what might cause this?  I would like to find
some
way to restart printing without taking all the smbd processes down, because
doing
so would mean stopping production lines (we're a manufacturing facility).

Thanks for any help you can provide!

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 commandentry 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

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.

Dave,

  If samba's spooling the jobs, and lp isn't picking them up,
I'd look closely at lp and its' status.  There may be a stalled
process that needs to be killed/restarted.  How many lp-related
processes are running?  Look for one that has been open since lunch
yesterday;  that may be the culprit.

Good luck,
  Jim

Jim,

I've restarted the lp spooling system more than once,
and I've checked to make sure that there are no hung
lp-related processes.  I have now also tried using all
absolute paths to the executables in the print command,
with no more success than before.

Thanks for the help,
