After installing CutePDF Writer, it will take you to a read me page. Which will explain you how to use the software.

Saving a file as a PDF is really simple in CutePDF Writer. You can simply go to File Menu and select "Print" and select CutePDF Writer as a printer.

Just like any printer properties, CutePDF Writer looks the same.

You can see the printer installed in your control panel from here.
