I had a similar issue with MacOS X 10.7 Lion (and earlier) clients not 
retrieving the PPD file from the server for classes. With MacOS X 10.8 
Mountain Lion Apple fixed the issue by using the libcups API.

Anyway as I had legacy MacOS X clients with users that didn't want to 
upgrade, so I created and applied the attached patch to a cups-1.6.1 server.

So now if you try to retrieve a PPD from a URI that looks similar to:
    http://servername/classes/poolname.ppd
it'll return the PPD of the first printer in that class.


Cheers,
Doug
