I have found the case in chrome that iframe is not ready for print. So I suggest to change the line:
setTimeout( function() { (opt.operaSupport && $.browser.opera ? tab : $iframe[0].contentWindow).print(); if (tab) { tab.close(); } }, 1000);
to
if (opt.operaSupport && $.browser.opera) { tab.print(); tab.close(); } else { $iframe[0].onload = function() { ($iframe[0].contentWindow).print(); }; }
