The default printer setting may change after you install a Windows Vista service pack on a Windows Vista-based computer

Support for Windows Vista Service Pack 1 (SP1) ends on July 12, 2011. To continue receiving security updates for Windows, make sure you're running Windows Vista with Service Pack 2 (SP2). For more information, refer to this Microsoft web page: Support is ending for some versions of Windows.


After you install a Windows Vista service pack on a Windows Vista-based computer, the default printer may change to Microsoft XPS Document Writer. Additionally, when you try to do a print job, you are asked to save the print job as a file.

This problem occurs most frequently if you had set a network printer as the default printer.


This problem occurs because many device drivers are reinstalled during the installation of a Windows Vista service pack. This can cause the default printer setting to be changed.


To resolve this problem, set the default printer manually. To do this, follow these steps:
  1. Click StartStart button , type
    Control printers in the Start Searchbox, and then click Control Printers in the
    Programs list.
  2. Right-click the printer that you want to use, and then click Set as Default Printer. A check mark on the printer icon indicates that the printer is now the default printer.
