This page tells you if this browsers 'object' tag supports Adobe's 'Acrobat' plugin in.

If you see a big red button button marked 'LOGO' above...

Then that's good. It shows that this browser can display Adobe Acrobat files using the 'object' tag.
This is the simplest (but also the least powerful) way of displaying a pdf preview. If you are using Internet Explorer, you will normally find that this test works, whereas it will usually fail with Firefox and Opera.

If you see the phrase 'No, it doesn't...' or nothing at all above...

Then that's interesting and probably OK unless you're using Internet Explorer. This test should succeed in Explorer, but may fail in Opera, Firefox too. This doesn't matter since a Printflo powered website will detect what browser you're using, and use the appropriate display method.
