Configuring compression in cups

[chippo at rmbam.co.za]

I have two cups schedulers running on remote ends of a WAN link, so that printers in both locations can be accessed by users at either location.  Sadly, I've noticed that the print jobs are consuming most of the bandwidth on the link, which should be being used for other stuff.

Searching through the source code, it looks to me as though the cups scheduler could compress the print jobs before transmitting them over the WAN link.  I see that at least, the cups scheduler will cope with compressed data if it receives it:
http://www.cups.org/str.php?L368

Is it possible to get the client-side scheduler to gzip up the print jobs before forwarding to the server-side scheduler?  If so, how do I configure it to do so?

TIA,
