Question about Epson TM-T20III

I set up 2 of them 2 years ago. Strictly according to the instructions. They need a bit more effort. But the instructions were good. In my case (due to the lack of availability of WLAN versions) it was the ones with the RJ45 connection. What I do remember is that you should assign fixed IP addresses to them.

Network printers are rarely plug and play, they have to be set up
