ASP.NET

In a web form 2010 application, I am creating letters that need to be sent to various customers that are generated in html and are sent to 2 or 3 customers at the at different addresses. However each letter needs to be the same. The only difference is the mailing address. Thus I need each letter to be generated on separate pages. Thus I would like to know what html command can be used to made certain each letter is printed on separate pages. Thus can you tell me what the command would be?

public JsonResult PopulateGrid()
       {
           var x = (from n in dbContext1.GetOrders("Melody Devoe") select n);
           List<string> items = new List<string>();

           foreach (var item in x)
           {
               items.Add(item.ToString());
           }

           //List<CentralBilling.Models.GetOrders_Result> returnList = new List<CentralBilling.Models.GetOrders_Result>();
           return Json(items.ToList(), JsonRequestBehavior.AllowGet);
           //return Json(items.ToDataSourceResult(request));
       }

string result = "<?xml version=\"1.0\" encoding=\"utf-8\" ?> 
                 <string xmlns=\"http://tempuri.org/\">
                     <AAA> 
                          <Code>5</Code> 
                          <Message>Send MT Error!.</Message>
                          <Time></Time>
                     </AAA>
                 </string>"
   XmlReader xReader = XmlReader.Create(new StringReader(result));
   while (xReader.Read())
   {
      ??????????????
   }
