How do I print on both sides of the paper (duplex) in Windows?

From your software program, select Print, open the print driver via Properties or Preferences, click the Layout tab, and select the appropriate duplex option from the 'Print on Both Sides Manually' drop-down list. The product will print the first side of all pages first; you then retrieve the stack from the output bin, place it printed-side down with the top edge first back into the input tray, and click OK at the computer to print the second side.
