Hello, anyone knows how to do a print script?

The thing is that I need to first open a popup page (like a 'preview the page') from where you are when you click at a print this page link) and then automatic open windows.print?

Again: every page at a site will have this 'print page' link, this link lives in some code in a template, so the link is not written multiple in every page around the site, so I need the popup to be dynamic and display the current page..

Tnx in advance!
