If you find yourself frequently changing one or more printer properties such as print quality or grayscale, you can set the default properties on each printer on your system to make your life easier.
Click Start -> Printers and Faxes. Right click on the printer you want to change, and select Properties.
Click on the Printer preferences… button, and you will see the familiar preferences window for that printer. Make any changes you want to the print preferences, and when finished, click OK.
These preferences will now be the defaults when you print a document on that printer.
