Thanks for the response. I called the 800# and the fellow told me to go to the Sharp Canadian website to get the driver that actually works!! The one from the Sharpusa.com site would go through the motions OK, but when you plug in the printer, Vista says it can't find a driver for it. Had to completely uninstall the "US" driver and download and reinstall the "Canadian" driver. Works fine now.
For anyone who needs it, the location is
Sharp.ca.
