Most modems have fax capabilities. PC faxing hasn't caught on in the office because so many faxes are sent overnight when phone rates are lowest. To use a PC as your office fax machine, it must run 24 hours a day. This method wastes power, and it's chancy.
Computers lock up at times from software conflicts or power fluctuations.
If that happens, fax reception is lost until the PC is reset. But one big advantage of PC faxing is the way you can preview, edit and forward messages right at your screen without ever handling a piece of paper. Just plug in the included power supply, plug an incoming phone line into the standard RJ-11 connection and press the Receive button. Leave the Store 80 on or turn it off as desired. No software comes with it, nor is there any need for control software or drivers, because the Store 80 appears to your fax modem as an ordinary phone line.
