Print a pdf with javascript or jquery

Question

I need to print a .pdf file (I generate it with jasperReport and I save it on a server) when I click on a print.gif button. Now I found this solution that works for Firefox

Answer 1

I believe the Problem is that the content is not loaded yet? I had the same issue in IE8. I had to save the document, reopen it, print, and close the window again.
