How do I print on both sides of the paper (duplex printing) on a Mac?

For automatic duplex printing on a Mac, click File, then Print, open the Layout menu, and select a binding option from the Two-Sided menu. For manual duplex, open the Finishing menu, click the Manual Duplex tab, select a binding option, print, then reinsert the printed stack face-up with the bottom edge feeding into the printer first in Tray 1.
