I have an old HP Deskjet 820cse printer that has been wonderful for my needs for many years & is still in very good condition. (It's been very good with ink.) Recently bought a new Dell Inspiration computer (64 bit) with Windows 7 Professional installed & this printer worked just fine when connected with a printer cord with USB connection. Upgraded to Windows 10 a few weeks ago (was told that I'd end up in the same situation as I was in with Windows XP having no support from Microsoft, so I should upgrade) & it would not print, even though it was listed as a printer in 'Hardware & Sound' in the computer control panel. My son tried to get it to work this evening & now it is no longer listed in 'H & S'. The 'HP Diagnostic Tools' site does not find that it even exists. The printer is connected by USB port, as it was with Windows 7. It is plugged in & has a green light on & the ink cartridges slide when the door is opened, as when it's time to replace them.
I have spent hours tonight looking at new printers & I am so confused (I'm old & I just need a simple printer). Please, if anyone can help me figure out how to make this HP Deskjet 820cse printer work on Windows 10, I would appreciate it so much.
