samba - Mar 2005 - Samba or Cups-Problem ?

Hi,

I'm using some kind of pseudo printer on our samba server to automatically 
produce PDF files. The smb.conf looks like this (the samba server is 
successfully conteced to an ADS):

[global]
        workgroup = ADS
        netbios name = pc103.ads.local
        realm = ADS.LOCAL
        security = ADS
        password server = win2ksrv.ads.local
        log level = 2
        winbind separator = +
        template homedir = /home/%U
        idmap uid = 10000-20000
        idmap gid = 10000-20000
        winbind enum users = yes
        winbind enum groups = yes
        winbind enable local accounts = yes
        template shell = /bin/bash
        log file = /var/log/samba/log.smb.%U
        max log size = 500
        printing = cups
        printcap name = cups
        cups options = raw

[pdfprinter]
        comment = Minolta Color PageWorks/Pro Ps
        path = /samba/pdfprinter
        print command = /samba/pdfprinter/pdfscript "%s" 
        printable = yes
        public = yes
        writeable = yes

[printers]
   comment = All Printers
   load printers = yes
   browseable = no
   printable = yes
   public = yes
   read only = yes
   create mode = 0700
   directory = /tmp

My problem is, that the script doesn't produce any PDF file. In the logfile
I
find the following message:

[2005/03/29 19:31:44, 0] printing/print_cups.c:cups_queue_get(900)
  Unable to get jobs for ipp://localhost/printers/pdfprinter - 
client-error-not-found

Okay, this is an error from cups, but what has cups to do with it? I don't 
want to use cups for printing, but a simple script.
I have used this construction already about two years ago with older versions 
of samba and cups and I of course compared the configuration files and all 
file/dir permissions.
Samba is version samba-3.0.9-2.3, cups is version cups-1.1.21-5.6, the system 
is SuSE 9.2.
Do I really have to set up some kind of dummy printer to use a script as a 
printer in samba?

Thanks for any help,

Stefan

The samba HowTo in chapter 20 says (^^^^ emphasis mine):

"ldd `which smbd`
libssl.so.0.9.6 => /usr/lib/libssl.so.0.9.6 (0x4002d000)
libcrypto.so.0.9.6 => /usr/lib/libcrypto.so.0.9.6 (0x4005a000)
libcups.so.2 => /usr/lib/libcups.so.2 (0x40123000)
[....]

The line libcups.so.2 => /usr/lib/libcups.so.2 (0x40123000) shows there 
is CUPS support compiled into this version of Samba. If this is the 
case, and printing = cups is set, then any otherwise manually set print
                                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
command in smb.conf is ignored. This is an important point to remember!
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Tip

Should it be necessary, for any reason, to set your own print commands, 
you can do this by setting printing = sysv. However, you will lose all 
the benefits of tight CUPS/Samba integration. When you do this you must 
manually configure the printing system commands (most important: print 
command; other commands are lppause command, lpresume command, lpq 
command, lprm command, queuepause command and queue resume command)."


So what you need is
> [pdfprinter]
>         comment = Minolta Color PageWorks/Pro Ps
printing = bsd
>         path = /samba/pdfprinter
>         print command = /samba/pdfprinter/pdfscript "%s" 
>         printable = yes
>         public = yes
>         writeable = yes
and you'll also need a

lpq command=/bin/true

otherwise your printer is going to show offline and jobs won't clear 
from the queue on the clients.

HTH,
