Hello,
Yes, the printer prints test pages and reports from its own console, and
documents via wifi from my iphone, but not from Debian. Even 11.0 with
non-updated cups. Same issue with an identical printer on another network -
that does print from Buster. I half suspected a router problem, but same
issues when Bullseye laptop and my printer are linked via iphone wifi hotspot.
Same issue when my Bullseye laptop is linked via EE mobile broadband router
(locally) to an identical printer (in another place, 10 miles away, so can't
check for differences regularly).
After using system-config-printer to print a test page on an auto-detected
driverless IPP profile, connected via 2.5GHz wifi to a router, to which the
Bullseye laptop is connected via 5GHz wifi, I get no output, and:

Is that number of client IDs (retries?) normal?
FWIW, do these permissions look right?

I also sometimes get "File '' not found" in system-config-printer's "printer

same printing from LibreOffice or kate.
Many thanks!
