No Double-Sided Print Option with Pixma iX6820 on Macbook

[jessicalee]

I can't seem to find an option to print double-sided when using my macbook to print to my iX6820 printer. Attached are photos of all of the options when printing, and double-sided just simply isn't an option. Does anybody have a way to prompt this setting to come up when printing?

I'm not sure it can. My printer does, and it lists Auto Duplex Printing in the tech specs. Your printer does not.
