Using the latest Mac OS, my printer setup does not display any option for duplex printing or printing on both sides of a page. No option is there and I've run the setup program more than once.
Maybe this is not relevant, but I have an HP printer as well. That shows the option of printing on both sides in the print. window, and I run the HP printer on the same computer as I do the Canon printer. The HP gives me the option, the G3270 does not. Huh?
