Normally, Epson does not supply macOS drivers along with its printer, but instead relies on the Apple printer data base to install the correct driver when you attach the printer. What have you tried? Sometimes resetting the printer data base may help. Here's how:
Remove the printer from USB and if it's wireless, turn it off completely then....
Open 'System Preferences' found in the Mac OS X dock, then open 'Printer & Scanners' which can be found in 'System Preferences'. Hold down the Control key (Ctrl) as you click in the list at the left, then choose 'Reset printing system...' from the menu that appears.
Turn the printer on, hook it up USB and see if your Mac recognizes it and installs drivers. After that, you can tackle getting it to run wireless. Epson instructions for wireless should be included with the printer instructions.
