LAN Fax
Local Area Network (LAN) Fax allows you to send faxes using the print driver on your computer to a fax
machine over a telephone line.
For details about using or configuring LAN Fax, see the print driver software help.
Note: Not all printer models support this feature. Some printers require an optional fax hardware kit.
