Setting Default Printer
If you have several printers connected to your computer, you can choose your primary or default printer. This is done by opening the Printers and Faxes dialog box. Right click on the icon of the printer you want to be your default and left click on the line Set as Default Printer.
Bonus Tip: Windows does not always sees just physical printers. There are programs that convert a document to editable and non-editable formates. PrimoPDF is a program that converts pictures or documents to a PDF format.
