How do I set my HP OfficeJet 4650 as the default printer on Windows?

On Windows 8.1 and 8, point to or tap the upper-right corner to open the Charms bar, click Settings, click Control Panel, then click View devices and printers. Make sure your printer has a check mark in the circle next to it. If not selected, right-click the printer icon and choose 'Set as Default Printer' from the menu. (Page 3)
