Fix : Windows is sending print jobs to the wrong printer

For some mysterious reasons, Windows can choose a new default printer - one automatically sends it to the print job (when I upgraded from Vista to Windows 7, it happened to me). To fix this disturbance in Windows 7 Click on Start (Windows icon in the lower-left corner of the screen) and choose Tools and Printers. Under Printers and Fax, right-click the printer that you want to make default, and select Set as default printer. If you're using earlier versions of Windows, these steps vary a bit.
