samba - Nov 2003 - Cups printing on Samba 3.0.1 from Win2000 SP4

I have a samba based domain controller with a CUPS printer working fine. 
  When I try to connect to a samba printer from  Win2000 I get the 
following in the samba log:

2003/11/04 20:38:02, 0] printing/print_cups.c:cups_queue_get(889)
   Unable to get jobs for ipp://localhost/printers/goucho - 
client-error-not-found
[2003/11/04 20:38:02, 0] smbd/service.c:set_admin_user(321)
   root logged in as admin user (root privileges)

Any clues are appreciated...

Here are the relevant parts of my smb.conf:
