Weird that you can’t just have the printer do this by default. But if you’ve ever wondered how to print something out double-sided then wonder no longer. Let me show you the way…
First you’ll want to have open a document that you hope to print. A MS Word file, spreadsheet, email, website, anything really.When you are ready to print, open the printing dialog box by selecting File >> Print… or by hitting the keyboard shortcut, Apple + P.
This ought to look familiar. Select the correct printer, number of copies, and whathaveyous. THEN, click on the third pull-down menu and look for an option labelled “Layout”. Select this!
Our dialog box should now change to present you with some new & different options. Most notably, the “Two-Sided” option. Click on this pulldown menu and select “Long-edge binding”. This will make your file print double-sided. (The long-edge binding refers to the orientation of the page. If you wanted to print a document that was formatted for a landscape style page then you would select “Short-edge binding”.)
That is all! Click print and you are done!
