Remove the wireless adaptor and connect the printer to the network.
The printer will pick up an IP address as DHCP is enabled by default.
Print the printer configuration page to get the IP address of the printer.
Type the printer IP address in the web browser. (default username and password is both Epson)
In the printer config page, change the SSID from EPSON_printer to the local wifi Address and type in the wifi password. Connect the wireless adaptor. The printer will now be connected to the local wifi.
From the printer config page, change the IP address to 200 and disable DHCP on the printer. We need to do this step else everytime the printer gets a different IP Address we have to type that in inTennis settings.
Go to printer setup in inTennis, type the IP address and print test page.
