Getting the Epson XP-231 Multifunction printer to work in Fedora 31 KDE spin

This new version of Fedora gave me a bit of a headache trying to get the Epson XP-231 multifunction printer to work.  The main problem was that the OS would not enable the printer and, regardless of my attempts, I could not get the rpm package with the drivers installed.

The Plasma assistant detected the printer, but could not find any drivers.  So, I first tried what has been working before: using a local package called epson-inkjet-printer-201204w-1.0.0-1lsb3.2.x86_64.rpm (which I downloaded and keep around) using either Discover or dnfdragora. Discover told me that the installation was successful, but the Plasma assistant still refused to see the driver.

When I used dnfdragora, it would not start and issue an error message about insufficient permissions. I made my user a sudoer, but it did not help.

Little did I know that the solution was a lot simpler that I expected.

All I had to do was to start dnfdragora and search "epson." This gave me a package with a newer version of the drivers, which I installed and, after that, I simply configured the printer with the plasma assistant, where the drivers could be selected this time.

For the scanner, I used megatotoro's procedure here again.

Now everything is good!
