ASP.NET中实现打印

怎样才可以调用打印机进行打印并且对纸张类型进行设置呢？
---------------------------------------------------------------

<OBJECT id="WebBrowser" height="0" width="0" classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"></OBJECT>
<script language="javascript">
function frmLoad()
{

WebBrowser.ExecWB(8,1);
WebBrowser.ExecWB(6,6);

}
</script>

---------------------------------------------------------------

直接调用IE的打印设置；

window.print();
---------------------------------------------------------------

<OBJECT classid=CLSID:8856F961-340A-11D0-A96B-00C04FD705A2 id=WebBrowser>
</OBJECT>
<script language="javascript" for=window event=onload>
self.focus();
WebBrowser.ExecWB(6,2);
</script>
---------------------------------------------------------------

Ie 6 not support WebBrowser
