When you print a section, it is printed to a PDF file and launched inside your browser if the PDF MIME type is set in your browser. The PDF file can be viewed online, or printed if you need a hard copy of a report.
The PDF format is created by Adobe and can be viewed outside of your browser if you have Adobe Acrobat Reader installed. Adobe Acrobat Reader can be downloaded from Adobe’s website at http://www.adobe.com/products/acrobat/readstep.html. If the PDF MIME type is not set in the browser, the browser “Save As” dialog box is invoked.
