How Do I Completely Uninstall All Traces of Removed Printers??

I had a printer software previously installed. Then I installed a different printer of the same company (Epson). I uninstalled one hoping to retain just the other. But when I wanted to use the only printer left on my system it gave me an option to use it or the other printer. But the other printer was "uninstalled". Then I uninstalled the other printer left.

It looks like remnants of the printers have stayed behind in my system and were not fully removed. How do I fully remove all traces of my printers?

Btw I contacted Epson and they were no help since I'm out of warranty!!!

Have you tried this option - This PC -> right Click -> Manage -> Device Manager -> Print Queues -> Left click -> then right click on the printer you want to uninstall by clicking uninstall device.
Hope this helps :)

I did that but it doesnt work. In trying to uninstall all traces of all printer software I may have messed it up. Apps that I used to install with no issues are now met with a pop message saying the following:

"The app you're trying to install is not a verified app from the store"

How do I fix it so I'm able to install apps without any popups like before?
