How do I perform manual double-sided printing through Windows?

From your software program's File menu, click Print and select the product, then click the Properties or Preferences button. Click the Finishing tab, check the Manual Double-Sided Printing checkbox, and click OK to print the first side. Remove the printed paper stack from the output tray, place it back into the paper tray in the same direction with the printed side facing down, then press the OK button on the control panel to print the second side.
