How do I set up fax on the HP Officejet Pro 6970?

You can set up fax using the HP printer software (recommended) or the printer control panel. For Windows, use the Fax Wizard during software installation or open the HP printer software, go to the Fax tab, and select Fax Setup Wizard. For OS X, use Basic Fax Settings from HP Utility. From the control panel, touch Fax on the Home screen, and then touch Setup. (Page 2)
