This method allows you to connect the printer directly to mobile devices without a wireless router.
You need to install the optional Wireless LAN Interface-P1 to use this function.
Make sure to install Epson Smart Panel on the device beforehand. Once you have connected the printer to the mobile device, you can print from your mobile device using Epson Smart Panel.
