How do I set up fax on the HP OfficeJet Pro 7720?

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