[cups.general] cups pdf and fax backends in rpm?

[Dave]

Hello,
    I've got a cups 1.3.3 server running on centos 5.1. It uses samba to 
allow windows printer drivers uploads and printing windows printers to a raw 
queue. This works fine. I'd now like to add in fax and pdf printing support, 
the latter where i send a document to the print queue and instead of 
printing it is converted and stored on a samba share. I've read on cups-pdf 
and was wondering if it was available in rpm form? As for faxing same 
concept take a document submission and fax it, i don't have a modem so it 
would have to go over email to a fax machine. Is this an issue?
Thanks.
Dave.
