Connecting to a Cups printer via Samba ( access denied )

I've managed to get samba 2.2.1a working on my 7.2 system. However.. Although other machines on my network can share the hard drive etc I get access denied when I try and share the printer to the same clients. I've changed the printer section to.. [printers] path = /tmp print ok = Yes printing = cups as described at cups.org it was the following. #[printers] # comment = All Printers # path = /tmp # force user = diddy # create mask = 0700 # guest ok = Yes # printable = Yes # printing = cups # browseable = No But I'm still have problems. Anyone got any ideas
