If your computer is connected to more than one printer, you can choose the default printer you want Windows to use to print your files unless you specify another one. The default printer is typically the printer that you use most often. When you start a print job without specifying a particular printer, the job is sent to the default printer. You can select a default printer in the Printers and Faxes window or when you set up a new printer. The default printer displays a black dot with a check mark in the printer icon.
