Computer not installing printer

[jeepin103]

I have an HP Envy Photo 7800 All-In-One printer installed, wirelessly.  I've had it for a little more than 3 years now and almost a year ago the computer (locally) stopped printing.  I was able to print anything from online.  I cleared out every printer I had listed, even the print to .pdf printer.  My printer then began to work again.  Now it's back to not working.  I have the HP Smart app, which sees the printer and shows the ink levels, etc.  No matter which avenue I take to attempt to install this printer, it just will not install.  I have tried everything I can think of to do and have been on the phone with tech support for some of it but we cannot seem to get this worked out.  Any suggestions?  I just don't know what else to do, short of scrapping it and getting another printer, which I really do not want to do right now.  Thank you.
