Hi, so I have a mid 2010 27" imac running Lion 10.7.1 and just recently bought a new Canon Pixma MG8120 printer to use with my imac but they won't connect. I called both Apple and Canon several times and nothing they suggested would work. I tried to download the drivers and softwares from the Canon website: http://usa.canon.com/cusa/consumer/...kjet_printers/pixma_mg8120#DriversAndSoftware but nothing happens after they install. My printer does have a wifi feature but I want to use the usb connection. I hooked up my Canon printer with my old macbook pro running tiger to make sure my printer is not defective and it works, but not with my mid 2010 lion imac. I checked the list of printers that work with Lion and it appears that my Canon Pixma MG8120 printer is listed but still refuses to work for some reason: http://support.apple.com/kb/ht3669 Can anyone help me with my situation? This is my last resort. Thanks!
