I'm glad it worked. In the past we had some issues with Xerox printers claiming IPP support, but Xerox wasn't interested in returning our calls to discuss the problems we were seeing with their implementation. Apparently someone else got them to address them, since the ones we were seeing were very basic and prevented printing at all.

Those are the ones mentioned in the RFCs for IPP. We don't actually care what the names are in the symbiont...we ask the printer what it supports and use that list. The RFCs just have a suggested list, but manufacturers are free to add additional names if they like.

'TOP' but printer at http://blah/ipp does not support media.
Seems to be saying that the printer doesn't support the "media" attribute at all, not that it doens't like your particular value. You can see what the printer claims to support with the MU IPP SHOW command:

As you can see, not all printers support all their features through IPP. This printer has a main paper tray as well as a manual feeder that will handle envelopes...but you can't ask for that through IPP as there's no MEDIA feature in the list. It is supported with their Windows Driver (non-IPP) though.

Asking Xerox about it is your best bet, but I'm guessing their implementation of IPP doesn't support picking a paper source and you can only print from the default source with that protocol. If they get enough requests, perhaps they'll do a firmware upgrade to add this capability, or not, or maybe they already have and you just need to install it. MU IPP SHOW
should let you find out at least what the printer does support at the moment though.
