Have to get the Epson wireless app sometimes in Google Play store. That may help. Also most important your phone and printer must be on the same Wi-Fi network if you have multiple networks like I do at home
I drive truck and utilize the printer to print forms for Canadian and US Customs for border crossings. Note 2 worked great with the printer. Recognized the printer and after selecting wifi direct I was set to go.
You need the printer and phone both connected to your wireless network. Don't connect to the printer's Wi-Fi. Then you should download the printer plugin for your Epson in. Search for printing in the Settings app.
