Vista Home Premium
Faxing isn’t included in Vista Home or Home premium. If you have an All In One (Printer/Scanner/Fax) machine that should work. There are two generic drivers for Vista on the net. One is from HP and the from Conexnant.
Or, you can use an Internet fax service like eFax, or Innoport. If you choose that route, I highly recommend Innoport for their world class support and uptime.
