The issue is the MIME typing on the CUPS server - if the server doesn't recognize the MIME media type then you may end up with extra filtering.
I'm not saying it can't work (because we have customers that use that configuration all of the time), it is just that we get a lot of support calls when people try to do Microsoft-style printer sharing to a server that is also hosting a CUPS printer driver on the same queue.
