Q: I have a mac, and when I go into setting for my printer when printing, the two-sided option is gray, so i can't click it. How do I print two-sided?
A: It sounds like you may have an issue with your printer driver. You can find a free download on Canon's site, as well as ask Canon Support for help. Here is a link: http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDetailTabAct&fcategoryid=238&modelid=15483
