How do I duplex print on Lexmark x6170 - Lexmark X6170 All-In-One InkJet Printer

Good day! Try to follow these steps on how to do duplex printing using the Print Properties settings. With a document open, click File, Print. In the Print dialog, click Properties (or Preferences, or Options, or Setup) button. The Print Properties screen appears. You'll see three main menus: Quality/Copies, Paper Setup and Print Layout. In Print Layout, select Duplexing to print on both sides of the paper. Hope this helps.
