Any Wi-Fi enabled Epson printer, can be setup through one or more of three different Wi-Fi modes - (1) Wi-Fi Infrastructure Mode Setup, (2) Wi-Fi Direct Mode Setup, and (3) Wi-Fi Protected Mode Setup (WPS). Following are the three different modes using which you can connect your Epson Printer wirelessly.
Wi-Fi Infrastructure Mode Setup
Wi-Fi Infrastructure mode requires a Wi-Fi router usually buit into your access point or Modem that you receive from your ISP . In this mode all your home devices are connected together over a wireless or wired network through an access point / router. You can setup your Epson printer to connect with your computer using the wireless access point too.

Connect the printer to your wireless network.

Many Epson printer models allow you to connect to the Wi-Fi network using the inbuilt control panel which usually also have a display menu. You can refer to the manual or user's guide for different model at https://epson.com/Support/Printers/sh/s1 .

Wi-Fi Direct Mode Setup
In Wi-Fi Direct Mode, your Epson Printer turns out as a wireless access point or router and allows you to connect upto 4 devices at a time. Your computer and other wireless device can connect directly to your printer and send the print job. When you enable Wi-Fi Direct mode, your printer shows you a network name and password. You are required to connect to the same network created by the Epson printer, in order to print from it.

That was all about the wireless connectivity using a router or an access point to connect your Epson printer to your PC. There are other methods also to connect your Epson printer to Wi-Fi, such as Direct mode or WPS method. In case you are facing any problem while connecting or could not find the wireless option in your Epson Printer then you can contact Epson technical support or a third party technical support provider for Epson Printer. I have found this technical support provider for Epson printer the most affordable- https://iguruservices.com/support/epson-printer-tech-support-toll-free/ as they charge you only when your printer is out of warranty.
