If I should install them, I do I need to install all 3? Hi bonniegiddens! Should I be manually installing these drivers? I noticed that on the Canon site, there are three drivers for the MX450 Series dated. I also get a recurring optional update notification for the 'Canon - Printers -Canon MX450 series FAX' even though I've sucessfully installed it several times. My Devices and Printers window shows a Canon MX450 Series. On my WIndows 8 desktop computer, I have an MX452 printer.
