Hi!

I just set up a PDF printer via Samba 2.2.5 according to the article given in 
the German magazine iX of March.

Now I have the problem that at the first time I done this a file appeared in 
the resulting pdfshare (the file created by Word which I test with) but 
afterwards I cannot get it running again (although I restarted smbd and 
nmbd). No file is placed inside the pdfprinter share directory.

I already searched using google but was not successful since most articles 
handle NFS and locks but NFS is not involved in my setup.

Some facts:

I installed a network printer with a "HP Color LaserJet PS" driver on my local 
Windows NT machine as user "nardmann" with admin rights.

I tried to actualize my "pdfprinter" in Windows but only see that it tries to 
get the status of the printer but gets an access denied ("Zugriff verweigert" 
in German).

I have attached two states of the log (log level 10) file, one before pressing 
F5 to actualize the status of the printer in the printer view of Windows and 
the other afterwards.

Best is to start at the end of the file to see the error message first.

I'm really clueless ... :-(

Here is my /etc/samba/smb.conf:
