1) My printer was not listed in programs and features.
I did delete it from Devices and printers and followed the rest of the instructions. I still cannot open the hp printer software or hp smart. The printer window still says no computer found. I think there is something wrong with the computer itself. In devices and printers the computer icon has an exclaimation point in a triangle by it. No printer has worked right since I deleted the photosmart D110 that I had. I didn't realize I had an HP computer also and may have accidently deleted something important. Anyway, getting new computer soon so hopefully everything will work out. Thank you for the help.
