Nothing has changed since I used my Epson Stylus SX435W printer last week, so today why did it only "copy" instead of "print" and now saying it's not connected to Wi-Fi (it is), nor paper not loaded correctly (it is). Layman's terms please!
Have you tried rebooting it and the modem (and the PC maybe) ?
Maybe you think it is on the WiFi yet it seems to think it's not detecting a connection.
