Hi Brian, My understanding is that self-check (where available) and test page printing are distinct processes, which may have been conflated here to some extent. I recall having a printer with self check capability where no feedback was reported (on windows, ages ago) if there were no problems. No disagreement re the independence of self checking functionality, but the command still has to be properly transmitted to the right endpoint. My printer doesn't have a self check facility so I can't explore if/how that works with a fax printer under different setup conditions. If the printer concerned is an OfficeJet 600, that is fax capable according to hp docs http://h10032.www1.hp.com/ctg/Manual/bpu60078.pdf in which case, I think it's possible this may be another case of the driverless+fax bug, where all jobs seem to end up in the outgoing fax queue and nothing prints, unless the queue was added via lpadmin. This does seem to be Bullseye-cups-related. I don't know yet if this printer supports driverless printing, or if driverless printing is in use, but the lack of test page output alone doesn't seem to reliably indicate a hardware or external-to-Debian problem. Just a thought, or three. Best wishes, Gareth
