How do I set up the fax feature on the HP OfficeJet Pro 6960?

You can set up fax using the HP printer software (recommended) or the printer control panel. On Windows, use the Fax Setup Wizard during or after software installation; on OS X, use Basic Fax Settings in HP Utility; or on the control panel, touch Fax on the Home screen and then touch Setup. (Page 2)
