samba - Jun 2004 - Not possible to print same document several times from windows clients

Hi,
we are encoutering some curious problems in our office network:
Print-jobs from windows 2k/xp clients are only printed once, although 
the user wanted the same document to be printed several times.
Does anyone have an idea? Has anyone had the same problem?

Some system info:
- server runs with Debian Woody
- Samba version is 2.2.3a-12.3
- Printer: HP Laserjet 4200n

- Extractions from smb.conf
[global]
   load printers = yes
   printcap name = /etc/printcap
   printing = lprng
[printers]
   comment = HP LaserJet 4200 PCL 6
   browseable = yes
   path = /var/spool/lpd/samba
   printable = yes
   public = yes
   writable = yes
   use client driver = yes
   create mode = 0700
   guest ok = no
    print command =      /usr/bin/lpr  -P%p -r %s
    lpq command   =      /usr/bin/lpq  -P%p
    lprm command  =      /usr/bin/lprm -P%p %j
    lppause command =    /usr/sbin/lpc hold %p %j
    lpresume command =   /usr/sbin/lpc release %p %j
    queuepause command = /usr/sbin/lpc  -P%p stop
    queueresume command = /usr/sbin/lpc -P%p start

- /etc/lprng/lpd.conf ist set that mc=5 to print multiple copies


Thanks a lot for any help.
