samba - Sep 2011 - Need help getting colour printing features restricted to a specific group

I?ve got a Ricoh multi-function printer/copier that I need to restrict the
colour printing functions to only members of the @ColorPrinting group. I?ve
two print queues for the Ricoh, one colour, one not. Unfortunately, even
users on the B&W queue can change the colour settings on the print dialog in
Windows and bypass the restriction and prints in colour.

Part of this likely is our CUPS configuration in tandem to our Samba
configuration. I?d appreciate it if someone knowledgeable about printing
with CUPS over Samba can help get this resolved. Our CUPS configuration can
be made available if we need it. Our Samba configuration follows:

Never thought about trying such a thing, but maybe editing the PPD of
the "B&W" printer so that it mimics a similar non-color capable
printer and therefore doesn't offer color options.
