[Samba] Printproblems in 3.0.3 - Postscript files contain log messages

[Alexander Skwar]

Hello!

I'm having a problem with Samba 3.0.3 on a HP-UX 11.00 server. In Samba,
I'm having a printer which allows me to create PDF files. For this, I
added the following lines to smb.conf:

[global]
        load printers = No
        printcap name = /etc/opt/samba/printcap

[printers]
        comment = Defaults for all printers
        path = /var/opt/samba/spool
        read only = Yes
        create mask = 0700
        printable = Yes
        browseable = No
        nt acl support = Yes

[pdf-generator]
        comment = PDF Generator (only valid users)
        path = /var/opt/samba/spool/pdf-generator
        printable = Yes
        print command = /var/opt/samba/bin/print-pdf    %s      ~%u/public_html/pdf-prints      http://%L/~%u/pdf-prints   %m              %I      %u      "%J"    &
        nt acl support = Yes

(The script /var/opt/samba/bin/print-pdf can be found at the end of this
message.)

The problem that I'm having, is that this printer doesn't work since I
updated to Samba 3.0.3 (before, I used HP CIFS 2.2.8a; the printer
worked). I suppose the reason that it doesn't work is, that the
printerfiles/postscript files that Samba creates, contain log messages
like this:

[...]
[2004/05/05 11:43:08, 3] rpc_server/srv_pipe_hnd.c:free_pipe_context(544)
  free_pipe_context: destroying talloc pool of size 600
[2004/05/05 11:43:08, 3] smbd/process.c:process_smb(890)
  Transaction 1907 of length 3804
[...]

Furhter on in the file I can find parts which look pretty much like
Postscript:

[...]
[2004/05/05 11:43:08, 3] rpc_server/srv_pipe.c:api_rpcTNP(1509)
  api_rpcTNP: rpc command: SPOOLSS_WRITEPRINTER
716 562 L
689 654 L
691 653 L
718 561 L
cp
0.801 0.535 0.113 r
[...]

"Sadly", this error doesn't come up all the time - just mostly. I also do
not know how to "force" this error to come up.

Q: Why is it, that I'm having these log messages in the printer files?

Thanks a lot,
Alexander

Hello.

Please find attached your PDF printout of the job

For the next 24 hours, you can also get the files at your pdf-print
directory at $HTTPBASE/.
