What is the difference between the online report (HTML) and the report I can save on my computer (PDF )?
Hypertext Markup Language (HTML) is what you see on your screen. If you print an HTML file, the printed results will look like what you see on your screen. Adobe Portable Document Format (PDF) reports are more aesthetically pleasing and easier to use than HTML reports. However, to view a PDF file, you need Adobe® Acrobat® Reader®, available free from Adobe.
