I have a printer that's being strange. Since the printer itself runs ipp, I'm trying to send it jobs directly with lp/lpstat/loptions/cancel &c, without talking to cupsd.

I get some responses, but nothing very helpful.

Does Wireshark/Tshark give you any clues as to what's going wrong with the exchange between host and printer? Looking at some sample traffic might be enough to allow you to avoid reading (most of the) RFCs... Or perhaps not.
