I'm running Ubuntu 20.04 LTS with an HP LaserJet P1006 connected by USB cable. On both this new installation and on a previous hard drive, the HP LJ P1006 would run until it's power was turned off. Upon restarting the printer, the printer would not print. (The system produces a message that the document has been printed, but the jobs remain in the queue.) In the previous installation, I had a Windows dual boot, and, if I exited Linux, booted Windows and printed, the P1006 would work and then would work on restarting Linux. Restarting Linux without getting the printer to work on Windows does not affect (the lack of) printing. I still have toner, so I'd appreciate any help. I ran the debugger, and got the message that it was unable to solve the problem. I can upload the results, but they're voluminous.
Thank you.
