Dear Brian, I tried the commands now on my Debian 11 installation on the external drive. Unfortunately increasing the timeout didn't change anything. ippfind still gives nothing. So I also could not set up a print queue and trying to print with the lp command.
The printer is found, but ipp can't communicate with it. I'm sorry. Cheers, Florian Am Do., 28.
