GM Print Preview is a Greasemonkey (Firefox add-on) user script, which searches a page for print stylesheets and if they are present the user can quickly and easily switch the page styles into these designed for print.
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.
How to install
- Install Greasemonkey add-on into your Firefox (you'll be asked to restart your Firefox afterwards).
- Go to the Greasemonkey Print Preview page and click on the button "Install this script" OR use the local link to download here.
