CUPS/Samba printing troubles

[TonyGroves]

I'm having trouble printing via Samba/CUPS.

The first "printer" I've set up on my Debian server is CUPS-PDF. I can "print" to it (it creates a PDF file in ~/cups-pdf ) at the server no problem. The printer is also accessible from Samba clients, but when I try to print to it from a Samba client, I always get "access denied" messages.

I can write to my home directory (including ~/cups-pdf) from a Samba client no problem, and my Samba and CUPS permissions are wide open, as far as I can see.

The relevant parts of the relevant config files are shown below, so I wonder can anybody see anything wrong there?

Thanks a lot.
