帮顶。遇到同样的问题。

除非用ActiveX，此外没有别的办法，因为Web不会保持不显示的数据。

实际还是使用了winopen 但是可以将页面移出 屏幕 这样即可达到楼主不想看到窗口的效果
===index.aspx中===========
<script>
function winopen(__URL)
{
window.open(__URL, "打印帮助 ", "toolbar=no,menubar=no,resizable=yes, scrollbars=yes,top=3000px,left=3000 ");
}
</script>
<input type= "button " id= "prtBt " value= "打印帮助 " onclick= "winopen( 'help.aspx?prt=yes '); " />
