Right now CUPS does not support it, and (at the moment anyways) we don't have plans to add support. There is a separate CUPS-based IPP sample project on Github hosted by the ISTO-PWG (https://github.com/istopwg/ippsample <https://github.com/istopwg/ippsample>) that has most of the bits in place for a complete IPP INFRA implementation. I have yet to finish the proxy implementation so I can test the last bits of the server implementation, but it is probably and easy/better place to start than retrofitting cupsd (which has a lot of legacy baggage to support...) > I suspect that physical printers need to act as both the > proxy service and output device.

It is coming, slowly, and mainly for high-end MFPs that get used in complex corporate/school networks. _________________________________________________________ Michael Sweet, Senior Printing System Engineer
