Just a quick update. Looks like Epson already has support for many of their printers and scanners. Epson Scan 2 is supported on Windows 11 ARM.
For example for my Expression Home 2205 Multifunction: https://download.ebz.epson.net/dsc/du/02/DriverDownloadInfo.do?LG2=EN&CN2=AU&CTI=98&PRN=XP-2200%20Series&OSC=W1164 would download Epson Scan 2. Windows 11 ARM is now an option when looking for downloads.
For printers, the Epson Universal Print Driver might work reasonably well, otherwise the basic Windows drivers work adequately.
There is also updates on Epson's upcoming full features drivers for Windows ARM on one of the webpages.
Hope this helps those still looking... This is an old post.
