we have seen the same problem on after a cups update to 1.1.21 on 
solaris 8 and found no soltution until now...

Unfortunatly we did a  samba update to 3.0.7 at the same time to, so I 
haven't been sure , if this is a cups or a samba problem.
Are you running the same samba version as before?

Thank you very much

Hansjörg
