samba - Mar 2005 - Problem with pdf printing

Hello, 
I'm hoping someone can help me.  I have several pdf printers set up and
when I print to them samba becomes unstable and several errors are
dumped to the log.  These pdf printers were working when I was using
version 3.0.6.  When I went to a newer version of samba the queue would
not clear on the windows side and no errors were logged.  Yesterday I
upgraded to version 3.0.13-1 and the errors started and the queue still
will not clear.  I have deleted several tdb files to no avail.  I am
using "printing = bsd" option as I have in the past.  Below is a clip
from the log. Please let me know if anyone needs more information.

I have a very similar problem with my pdf printers. I have the following 
in my [global] section.
printcap name = cups
printing = cups
cups options = "raw"

and my pdf printer share now has
[pdf]
comment=PostScript to PDF Converter
printing=bsd
public=no
guest ok=no
create mode=0600
path=/var/tmp
printable=yes
print command=. /etc/sysconfig/rc.sysadm; \
  ulimit -c 0; \
  ulimit -S -d $PDF_MEM_LIMIT; \
  ps2pdf %s "%H/%J.pdf"; \
  chmod 640 "%H/%J.pdf"; \
  rm -f %s
lppause commandlpresume commandlpq command=lpq -P'%p'
lprm command=lprm -P'%p' %j
queuepause commandqueueresume command
and it now shows the printer as online and the printjobs show up and get 
removed just as they should.

All it took to change the printer status displayed on the windows xp pro 
workstation from offline to online, was to add a "real" lpq command 
line, (lpq -P'%p'). Now all looks fine from the workstations viewpoint. 
BUT on the server I now have repeated entries of cups telling samba that 
it does not know the printer 'pdf'. Win one, loose one. ;-)

level 3 error msg
lpq: Unknown destination "pdf"!
[2005/03/27 22:20:00, 3] printing/print_generic.c:print_run_command(62)
   Running the command `lpq -P'pdf'' gave 1


I start to wonder what "dammage" it would do to set lpq to
lpq command =/bin/true
for my pdf printer? ;-)

HTH
