That worked, and it's now printing normally after reboot via the added profile, thank you Eduardo.
Not sure what's happened though as it worked perfectly with both auto-detected and manually-added printer profiles from Bullseye until a week or two ago. My logs suggest no update to system-config-printer. I did change the printer's hostname (on printer console) but both the printer and laptop have been restarted several times since then, printers re-added and re-auto-detected etc.
HTTP_STATE_WAITING Closing for error 32 (Broken pipe)
- appears in the error log for jobs it is now actually printing, so that seems to be unrelated.
I don't like it when things stop working without explanation.
Why should adding via the command line work, but not via system-config-printer or localhost:631?
Any further debugging tips would be appreciated.
Thanks,
Gareth
