How do I print from a mobile device using the HP Color LaserJet Pro M255 M256?

You can use the HP Smart app by scanning the QR code or visiting 123.hp.com, installing the app, and following the onscreen instructions to connect and print. Alternatively, you can use Wi-Fi Direct (wireless models only) by turning on Wi-Fi on your mobile device, searching for wireless networks, and selecting the printer shown on the printer control panel.
