Re: tmy HP LaserJet 3800 operstiong buttons on front...
Driver could be corrupt. Disconnect the printer or at least be sure it is turned off.
I'd do both and reinstall the CD software program that came with
the printer. When the software program asks you to connect the
printer to the USB port, do so and it should again work properly.
Hope this helps. Bud
