How to get a class to support duplexing?

When I sniffed the network traffic, I saw that the machine running Firefox sent
a GET for /printers/class-name.ppd, which came back as 404.  So there was no PPD offered at all.  This is with CUPS 1.3.

In the meantime, I came up with a workaround:  Create a printer with a simple backend Perl script that re-queues the file (via lpr) to the class.  Give that printer an appropriate PPD.
