I have a HP Photosmart 7550 and a pc with Windows 2000. Whenever I turn the printer off and then on again, the monitor developes vertical colored lines across the entire screen and I need to do a hard shut down (because I can't see beyond the lines). I turn the pc on again and everything is fine. I can print to it, so I know it works. I've unistalled the previous driver/software and reinstalled HP new driver/software, but no luck. Looking for a little help. I'm out of ideas as to what it can be. Thanks.

It sounds like it could be some sort of electrical interference. Try plugging the printer into a different AC outlet or try temporarily disconnecting the data cable then turn it on and see what happens.
