Hp Photo Envy 7800 is stuck on the booting up screen. It says hp with the blue line underneath a one blue dot. I have unplugged the printer as suggested and plugged back in . I have unplugged the printer and while unplugged held the power button for 15 seconds up to 60 seconds, plugged the printer back in and still nothing. I have restarted the computer. I have switched the default printer off the envy and onto a different printer. HOW can you reset the printer if it "doesn't think the printer is on"
Please give me the clue. This is NOT that old a printer and we do NOT use it a lot for it to break!!!!!!
