Hi,
The Epson ET-2760 and WF-2760 are listed in About AirPrint - Apple Support.
Do you have one of these models?
If so, an AirPrint-enabled model can be used without additional drivers, provided that the printer and the Mac computer are connected to the same network (Wi-Fi router).
If necessary, you could perhaps reset the printing system and re-add the printer to use AirPrint. Please see the following links for details.
Reset the printing system on your Mac to solve a problem – Apple Support (UK)
Add a printer to your printer list so you can use it on Mac – Apple Support (UK)
If there is a problem with device discovery in connection with AirPrint, the following power-cycle procedure (in this order, with these waiting times) can be tested: Power off the Wi-Fi router, the printer, the Mac, and all other devices/computers. Wait two to three minutes. Power on the router. Wait two to three minutes. Power on the printer. Wait a minute or two. Power on the Mac. Finally, power on all other devices/computers.
