[Samba] SOLVED Samba 3.0.0, CUPS support - "Unable to open printcap file cups for read!"

[Fran Fabrizio]

I'm still having print problems.  I'm beginning to wonder if it's my
version of CUPS rather than Samba.  When I print from my Windows Samba
clients, the job shows up in the /var/spool/cups directory, and CUPS web
admin says the job completed, but it never prints anything.  Same thing
from linux samba clients works fine (i.e. if I do 'smbclient
//ds119b/myprinter' and then 'print /etc/printcap', it works fine).

What version of CUPS?  I have the following RPMs:

cups-devel-1.1.17-13.3.0.3
cups-1.1.17-13.3.0.3
cups-libs-1.1.17-13.3.0.3

Samba 3.0.0 built from source, all standard config settings, on Redhat
9.

My entire smb.conf (mostly based off of the samples in the O'Reilly
book):
