It DID print a PDF - in a very simple and fast way. However, it was not what I was looking for (I need to print a DIV longer than a screen height).

Bad integration with graphic files in the web page.

La pagina stampata come PDF non rispecchia assolutamente l'aspetto del sito visualizzato sullo schermo. Da un'estensione creata appositamente per questo scopo, aspetto un po' di più rispetto del driver stampante del browser...

The printed page does not reflect the original page layout seen on the screen. Maybe it works well with the plain text pages, but for more complicated layout it does the same mess as the standard printer driver of the browser...

This app has a one click action, so that's good. The significant let down is that it simply prints what is visible in the window. That means, if content needs to be scrolled to, don't expect the pdf to include it - it doesn't. For me, that makes this app useless since there are other ways to capture the screen.

When "printing" a page to PDF, it totally ignores any @page CSS. I haven't yet found if the CSS @print rules are actually implemented in Firefox (I would hope so!) but this extension doesn't use them.
