我在自己程序中导入 smsx.cab文件后 代码如下:   <html xmlns="http://www.w3.org/1999/xhtml" >   
<head runat="server">   
       <title>无标题页   </title>   
       
</head>   
<body>   
       <form id="form1" runat="server">   
       <div>   
           <!-- MeadCo Security Manager -->   
           <object viewastext style="display:none"  classid="clsid:5445be81-b796-11d2-b931-002018654e2e"  codebase="smsx.cab#Version=6,3,435,20">   
             <param name="GUID" value="{232E61C9-1E90-4657-AEDB-6F02F3B2EE37}"/>     
             <!--   <param name="Path" value="sxlic.mlf"/>-->

            </object>                  
            <script defer>   
            
            
            
         function SetPrintSettings()   
          {  // -- advanced features   
            factory.printing.SetMarginMeasure(2);    
            // measure margins in inches     
            factory.printing.printer = "HP DeskJet 870C";   
            factory.printing.paperSize = "A4";   
            factory.printing.paperSource = "Manual feed";   
            factory.printing.collate = true;   
            factory.printing.copies = 2;   
            factory.printing.SetPageRange(false, 1, 3);   
             // need pages from 1 to 3  // -- basic features

            factory.printing.bottomMargin = 1.0;   
          }   
        function Print(frame)   
         {   
           factory.printing.Print(true, frame)   
            // print with prompt   
         }   
           </script>   
      
           <input  type="button" id="b1"   value="打印本页"   onclick="javascript:document.all.factory.printing.Print(false);"/>      
       <input   type="button" id="b2"  value="页面设置"   onclick="javascript:document.all.factory.printing.PageSetup();"/>      
     <input   type="button"  id="b3" value="打印预览"   onclick="javascript:document.all.factory.printing.Preview();"/>       
               
       </div>   
       </form>   
</body>   
</html>   在自己电脑IE7上访问没问题,可是在其他电脑 IE7 上访问javascript就会提示 document.all.factory.printing 为空或不是对象!!   
怎么办~~~怎么回事~~~   谢谢`?
