js打印无法设置设置默认项？主要是ActiveXObject("WScript.Shell")找不到？

var RegWsh = new ActiveXObject("WScript.Shell");

每次点击打印预览跑到这个代码就到catch里面去了
怎么解决？
我的打印代码如下：

<OBJECT classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2" id="wb" width="0" height="0"></OBJECT>

<div id="bankwrap">

    <p class="Noprint">

        <span style="cursor:pointer; color:#0000FF" onclick="printpreview();">打印预览</span>

        <span style="cursor:pointer; color:#0000FF" onclick="prints();" class="Noprint">打印</span>

    </p> 

 </div>

 <div class="banktitle">内容</div>

</div>

js代码：



    //配置网页打印的页眉页脚为空

    function pagesetup_null(){   

        try{

            var RegWsh = new ActiveXObject("WScript.Shell");           

            hkey_key="header";           

            RegWsh.RegWrite(hkey_root+hkey_path+hkey_key,"");

            hkey_key="footer";

            RegWsh.RegWrite(hkey_root+hkey_path+hkey_key,"");

        }catch(e){}

    }

   //打印页面预览

    function printpreview(){

        pagesetup_null();

        try{

            wb.execwb(7,1);

        }catch(e){

            alert("您的浏览器不支持此功能,请选择'文件'->'打印预览'");

        }

    }
