One Click Print Preview for Firefox

In my previous post I expressed the intention to introduce a new and easy way how to get a print preview of a web page. And here it comes!

Let me introduce you Greasemonkey Print Preview user script. The script scans a page and if the page contains a stylesheet for a printer (print media) the script displays (in the top-left corner) a semi-transparent bar with a link to the print preview of the page.
If you click on the link the page stylesheets are switched and you can see the page as it would print on a printer. There is also a keyboard shortcut - [ctrl]+[alt]+p.
It is possible to switch off the print preview bar (the keyboard shortcut remains functional).

Why would you install the script?
Because this is the easiest way how to get a print preview. There are other ways, but they are not as quick and straightforward as using Greasemonkey Print Preview.
