Print double-sided pages with your Mac
You can print a document with double-sided pages if your printer is capable of printing to the front and back of a page.
Note: The following options might not be available for your printer or app. If these instructions differ from what you see onscreen, refer to the documentation that came with the app or printer you’re using.
With a document open on your Mac, choose File > Print.
Choose On or Off from the Double-sided pop-up menu.
You can also choose On (Short Edge) to set the document to print ready for binding at the top of the page.
Click Print.
