Big Sur & Epson Drivers

Hi,

Do you mean WF-4630 or WF-4720?

Both these models appear in About AirPrint - Apple Support as printers supporting the driverless AirPrint technology, which Barney-15E was referring to. Software from the printer manufacturer may or may not add functionality.

WF-4620, a local model? If so, you could perhaps try AirPrint as suggested (normally, only the models in the above article are supported), or one of the drivers for the other models.

Try using AirPrint. Add the Printer and in the setup dialog pick the AirPrint drive from the "Use" popup menu.
