How do I tie in my iPhone to my hp 6970 printer

Hi,

You will need a Wi-Fi router. Make sure that the printer has been connected to the Wi-Fi router (if necessary, use WPS). Next, ensure that the iPhone and the printer are connected to the same network.

The HP OfficeJet 6970 All-In-One is listed in About AirPrint - Apple Support.

The following power-cycling sequence could perhaps be worth testing: Power off the Wi-Fi router, the printer, the iPhone, and all other devices/computers. Wait two to three minutes. Power on the router. Wait two to three minutes. Power on the printer. Wait a minute or two. Power on the iPhone. Finally, power on all other devices/computers.
