Printpreview page not showing in firefox

Question

By using window.print() in JavaScript, it does show a print preview in Google Chrome, but not in Firefox. Is there any solution for this?

Answer 1

In Firefox, this is not possible. Your only option is calling window.print, which only opens the Print dialog. Firefox extensions are able call PrintUtils.printPreview, which opens the Print Preview window, but this API is not visible from the JavaScript code of webpages.
