Jay, in you mail you stated you set smb.conf to use client driver for printing but you forgot to uncomment that line (at least in your email). Maybe that would help. I never know what will work with samba but its worth a try...
Good luck
# if you want to automatically load your printer list rather
# than setting them up individually then you'll need this
printcap name = /etc/printcap
load printers = No
# use client driver = Yes
Do You Yahoo!?
