How do I make the printer my default printing device on Windows?
On Windows 7, click Start and then Devices and Printers. On Windows 8/8.1, open the Charms bar, click Settings, then Control Panel, and select View devices and printers. If the printer does not have a checkmark next to it, right-click the printer icon and choose Set as Default Printer from the menu. (Page 3)
