How to Set up the Fax Modem on Your Laptop
The fax machine on your laptop is really nothing more than a remote printer. Although it's the modem's hardware that carries out the faxing, you need to look for your laptop’s fax machine in the list of Printers: from the Start menu, open the Control Panel, and then open the Printers or Printers and Faxes icon.
If you see a fax machine or anything named Fax in the list of printers, you're all ready to go.
Note that although the fax machine appears as an icon in the list of printers, you don’t use that icon to send a fax.
If you don't see a fax machine in Windows Vista, your copy of Windows Vista may not come with faxing abilities; you need to get a third-party fax program for your modem.
To add the fax printer to Windows XP, click the link, on the left side of the Printers and Faxes window, that says Install a Local Fax Printer. Heed the directions to complete the task.
