Duplex Printing on a Mac

What is duplexing? The term duplex refers to printing on both sides of the page, e.g. printing "double-sided". Only printers with duplexing capability (formerly an add-on unit, now usually a standard feature on modern printers) will allow you to print double-sided.

Enabling Duplexing

First, make sure the computer knows the printer is able to duplex:

  1. Go to the Apple and choose System Preferences.
  2. Click Print & Fax.
  3. On the left, select the printer you wish to use.
  4. Click Options & Supplies
  5. A new window will appear, it may look different depending on your operating system version:
    • 10.5+ Across the top it will say General | Driver | Supply Levels. Select Driver.
    • 10.4 At the top there will be a drop down menu, select from it Installable Options.
  6. Make sure there is a check box for "Duplex Unit".
  7. Close this window and the Print & Fax window.

Printing as Double-Sided varies by application, but in general: Open a document, go to File, choose Print, then pop up the "Copies & Pages" menu and choose Layout. Click the button for "Long-edged binding". Click Print.

Creating Alternate Presets

If you want to easily switch between single-sided and double-sided printing, you can create a preset:

From most applications (e.g. Microsoft Word):

  1. Go to File and choose Print
  2. There will be a drop-down menu that will have an option for Layout. Select Layout.
  3. You will then get more options, including one for Two-Sided. Select "Long-edge binding"
  4. Towards the top, you will see a drop down menu for "Presets". Select "Save As" and name it "Double-Sided".
  5. Now change the Two-Sided to "Off" and save the Preset as "Single-Sided".

When you want to print double-sided, go to the Presets menu and choose "double-sided". In our experience, that "double-sided" preset will stay selected until you choose something different. When you want to print single-sided, go to the Presets menu and choose "single-sided" instead.
