I have installed the Epson drivers on several PCs and it's always been a pita. There are a load of drivers and utilities and it's very difficult to figure out what you need.
I think what you need is the APD (Advanced Printer Driver). I have APD_456dEWM.zip which I think I used successfully. There are probably newer versions available. You should be able to download one from https://download.epson-biz.com/
The zip file includes an install guide PDF. I'm pretty sure I followed the instructions carefully.
One thing to note is that I think connecting the printer before installing the drivers may have been a mistake. You may need to delete the printer before running the installer.
