$("#print").on('click', function () {
        var child = window.open("image.jpg", "_blank", "location=0,toolbar=0,scrollbars=1,fullscreen=1,menubar=0");
        //any way to know/wait for image to load?
        child.print();
    });

Any way for my parent window to know that the child window has completed loading the image prior to calling .print()? If they were trigger happy they would end up printing a blank page.

I've tried both:

child.attachEvent("onload", function () { child.print(); });

and

child.attachEvent("DOMContentLoaded", function () { child.print(); });
