How can I enable two-sided printing on my Mac with OS Yosemite?
I have been trying to print double sided and watched many of the videos online about how to enable this option in Office, however, most of the videos were not from the latest OS and are outdated. Is there a different way to enable this setting on OS Yosemite? The option in Office is grayed out, and I need to figure out how to change the printer settings, but when I try to go through the System Preferences, and then Printers and Scanners, and Printer Queue, and Settings, there are no options relating to printing two-sided.
MacBook Pro with Retina display, OS X Yosemite (10.10.4)
