mPrint Extension Doesn't Work

Hi there, I tried to use mprint extension in Yii 1. When I clicked the print icon, there wasn’t responses and error. It just icon which useless. So, anybody could help me ?

this’s my code on my view :


     $this->widget('application.extensions.mPrint.mPrint', array(

          'title' => 'Manage Task',          //the title of the document. Defaults to the HTML title

          'tooltip' => 'Print',        //tooltip message of the print icon. Defaults to 'print'

          'text' => 'Print Results',   //text which will appear beside the print icon. Defaults to NULL

          'element' => '#Query2',        //the element to be printed.

          'exceptions' => array(       //the element/s which will be ignored




          'publishCss' => true,       //publish the CSS for the whole page?

          //'visible' => Yii::app()->user->checkAccess('print'),  //should this be visible to the current user?

          'alt' => 'print',       //text which will appear if image can't be loaded

          'debug' => true,            //enable the debugger to see what you will get

          'id' => 'print-div'         //id of the print link



Thank you !
