I cannot use my printer because it says the
drivers does not support the operating system
(windows 7)
No idea which 'it' you are referring to, but the Canon site lists your printer and has a driver that it says works with Win7 - you do have to select the OS and language (I checked English) but I'm sure you can manage that. "I've always been mad, I know I've been mad, like the most of us..."
Go to the Canon website for update drivers. Google for Canon drivers for Win 7... simple! Home Page http://ewen.uuuq.com/
