Just a short note to confirm that I tried this at work - a Red Hat 9 server I have hosting our intranet. I built an RPM from the SRPM available on the Cups-PDF website, which was easy enough once I'd installed a few devel packages through yum. Set up the printer as before and then shared it through Samba (which happened automatically - because Samba is configured to publish all printers). A few colleagues and myself ran some test jobs through and they were mostly successful, one failure occurred with an overly complicated Visio drawing which left Cups spawning Ghostscript processes every few hours which took up all available processor resources, but for converting Word documents it was fine.
