How do I print from an Apple iOS or Android mobile device to the M277?

For Apple iOS devices using AirPrint, open the item to print, select the Action icon, then select Print, choose the printer, and tap Print. For newer Android devices (4.4 or newer), open the item, select the Menu button, then select Print and choose the printer; some devices may require downloading the HP Print Service plugin from the Google Play store. For older Android devices (4.3 or older), download the HP ePrint app from Google Play. (Page 8)
