Did go to the Support page and found that I already had the driver and not sure if that was the problem. But I did follow the instructions, not sure what did the trick, but the printer did show on the devices list and I could select it and somehow it showed as a green check mark and ready. But the light on the printer was still blinking!! tried shutting it off then on, no help. Then tried disconnecting the power cable, reconnected it, still blinking. Although no note, took it apart and checked for paper jam. No help, still blinking.
Then remembered a problem I had earlier with print cartridges (HP cartridges). Have heard that HP somehow has a chip in the cartridge or some way to make the printer think the cartridge is empty or faulty so you have to buy a new HP cartridge. Well, I have found I can get the cartridges refilled by "Cartridge World" in Houston, don't know if they are everywhere. But took the black cartridge out and voila, the blinking stopped. So you may think a faulty or empty cartridge, but had gotten a replacement a month ago and it worked over that month until the printer stopped dead in the middle of printing the last page. So, P.O.'d made a trip back to Cartridge World to ask them to check the cartridge and the guy went to the back to check, but even before he checked, said felt, weight-wise, the cartridge was still much full. He said HP does this all the time, changing something so to them, it is a cat and mouse game where HP makes some change and blooey. Guess it's their way of trying to capture more of the cartridge market. But they exchanged the cartridge and I put it back into the printer and wonderfully, the blinking light stopped and came to steady green ready light. Ran a couple of test pages and now everything fine again.
So thanks for your direction and help and to anyone else with anything close to this kind of a problem, suspect HP cartridges and their policy. I just know that I will try anyone else's printer next time. HP has shot itself in the foot for the last time for me.
But thanks for your time and to BleepingComputer for having the format / forum to ask these kind of questions; and that's also why I donated to their cause to defend themselves again the post they have posted.
