oh btw, I recently had a printer issue that might be a bit similar in the cause, although different symptoms. I triggered it by using a different method to connect to the printer, out of the multiple of addresses IPP/DNS/etc./etc. I don't recall which one it was at the time, but one of connecting addresses drove my printer absolutely insane, causing it to require pulling the power, pull out the ink, and re-insert, wait 4-5 minutes for it to troubleshoot it. All this trouble, only because I used a different connection method, exactly the same driver too. I could repeat it as well, I went back to it again, and it happened again. The moment I used another address, it acted normal. This was on Qubes 4 as well, btw. So this is also something I'd suggest you try as well, try connect with a different address method, see if it can finish the print if you do that. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
