Make the "call" from where? Are you wanting to take a screenshot of a visitor's browser from a webpage?

If you want a print preview, can you not just use File > Print > Preview? Works for me.

You can only open the print dialog with JavaScript code on a web page.

You would need an extension to open the Print Preview window.

• PrintUtils.printPreview(PrintPreviewListener);

There are some extensions that you can look at to see if you can modify them to suit your needs.
