I shut the firewall down ("systemctl stop firewalld"), ran test pages. Same non-results, except that system-control-printer now reports: Idle - Print job canceled at printer. I tried increasing the logging, which involved stopping and restarting the cups service. In the process of doing that, the client and server both managed to forget the printer. I re-installed it. On the server, I have one instance of the printer, protocol: hp:/usb/HP_LaserJet_MFP_M232-M237?serial=VNB4J02590 On the non-working client, cups discovered two versions of the printer: dnssd://HP%20LaserJet%20MFP%20M234sdw%20(C0FB67)._ipp._tcp.local/?uuid=d532fa73-f559-43ca-9f8e-1eef16972345 ipps://HP%20LaserJet%20MFP%20M234sdw%20(C0FB67)._ipps._tcp.local/ I have been testing both and getting the same results. > > - How are the working clients connected to the printer (protocol > wise)? implicitclass://HP_LaserJet_MFP_M234sdw_C0FB67_/ > - Is the non-working client using that same protocol? Clearly not. So I had the working client discover the printer again. It offered the same two as I have on the non-working client. Both printed test pages. ipps://HP%20LaserJet%20MFP%20M234sdw%20(C0FB67)._ipps._tcp.local/ dnssd://HP%20LaserJet%20MFP%20M234sdw%20(C0FB67)._ipp._tcp.local/?uuid=d532fa73-f559-43ca-9f8e-1eef16972345 > - If you do not use MDNS and point manually to the server, does it > work any better? I tried setting up a printer manually on the non-working client. ipp://hawk.localdomain/printers/HP_LaserJet_MFP_M232-M237 No test page, and I got: Processing - The printer may not exist or is unavailable at this time. However, I checked the CUPS on-line documentation, and did not find any documentation on how to set up a URI, so it's possible I did that incorrectly. I also enabled "port 9100" printing on the printer, and went directly to it: socket://hpm234ethernet.localdomain:9100 The printer spun its wheels, reported an error and stopped without printing.
