PPFax overview
Fax creates the faxes and then sends them to WinFax PRO. WinFax PRO manages and dispatches the faxes. WinFax PRO must be set to be part of the Windows Startup Group, and its dialing options must be set correctly inorder to work with PlanetPress Fax. The job is finally output by the local installation of WinFax PRO on the PlanetPress Fax host computer.
Within the WinFax Pro interface there should be an option to add various different devices inwhich you could fax from. Try contacting symantec for help to configure your multi-purpose printing device.
