IE8页面打印问题

下面这段页面打印的JavaScript代码，原来在IE6是可以调用的，但是在IE8却不适用了
请问一下，有没有IE8适用的打印代码？
或者，有什么方法解决这个问题。。。。。

        function PrintReport() {
            var yemei;
            var yewei;

            yemei = String("<%= lblyemei.text %>");
            yewei = String("<%= lblyewei.text %>");
            sPrint.style.display = 'none';
            factory.printing.header = yemei;
            factory.printing.footer = yewei;

            factory.printing.topMargin = 0.2;
            factory.printing.bottomMargin = 0.2;
            factory.printing.leftMargin = 0.4;
            factory.printing.rightMargin = 0.4;
            factory.printing.paperSize = 9;
            factory.printing.print(false);
            document.all.WebBrowser.ExecWB(6, 6);
            //document.all.WebBrowser.ExecWB(45,1);
            sPrint.style.display = 'block';
        }
