What is Wi-Fi Direct and how do I enable it on the M428/M429?

Wi-Fi Direct allows Wi-Fi capable devices such as smartphones, tablets, or computers to make a wireless network connection directly to the printer without using a wireless router or access point. To enable it, open the Dashboard from the Home screen, touch the Wi-Fi Direct icon, touch Setup, and if Wi-Fi Direct is off, touch Wi-Fi Direct and switch it on. (Page 4)
