Samba & CUPS - Could not start print job

[Aleksandar B. Samardzic]

Ok, thanks to advices from some fine people my printer is now visible from 
Windows clients and I even managed to have printer drivers stored on Linux 
machine and downloaded to clients when installing printer. However, when 
I try to print from some client, error message from subject line ("Could not
start print job") appears. Server is Samba 2.2.0alpha3, clients are 
Windows 2000 Workstations, CUPS is 1.1.6, and my smb.conf is as attached 
to this message. I've tried to raise Samba and CUPS log levels, but found 
nothing in logs that could direct me how to further debug problem. Any idea
how to proceed?

Thanks,
Alex
