How Do I Print A Child Page Using C# Or Jquery

protected void EmpSC_Click(object sender, EventArgs e)
     {
         EmployeeSpDataSet dataset = new EmployeeSpDataSet();
         StringBuilder sb = new StringBuilder();
         var AllEmp = _service.GetAllEmployeeDuty().OrderByDescending(x => x.EndDate).GroupBy(x => x.Employee_Id).Select(x => x.First()).Take(3).ToList();
         if (AllEmp != null)
         {
             for (int i = 1; i <= 3; i++)
             {
                 var empsp = AllEmp.FirstOrDefault();
                 var emp = _service.GetAllEmployee().Where(x => x.Id == empsp.Employee_Id).FirstOrDefault();
                 dataset.EmployeeScpass.Rows.Add(emp.Id,
                     emp.Name,
                     emp.Cnic,
                     empsp.ToSectorName,
                     emp.ImgBody, ""
                     );
                 sb.Append("<table style=\"height:324px; width:1008px\">");
                 sb.Append("<tr>");
                 sb.Append("<td>");
                 sb.Append("<table style=\"height:323px; width:504px; background-image:removed(../Images/PassFront.jpg)\">");
                 sb.AppendFormat("<td><img src=\"EmpPicture.ashx?id={0}\" style=\"height:200px; width:200px; margin-top:41px; margin-left:17px;\" /></td>", emp.Id);
                 sb.Append("<td ><table style=\"height:20px;margin:30px;\">");
                 sb.AppendFormat("<tr style=\"height:116px;margin:30px;\"><td> </td><td>{0}</td></tr>", emp.Name);
                 sb.AppendFormat("<tr style=\"height:26px;\"><td> </td><td>{0}</td></tr>", emp.Cnic);
                 sb.AppendFormat("<tr style=\"height:95px;\"><td> </td><td>{0}</td></tr>", empsp.ToSectorName);
                 sb.AppendFormat("<tr style=\"height:13px;\"><td> </td><td>{0}</td></tr>", emp.Id);
                 sb.Append("</table></td></tr><tr><td></td><td></td></tr></table></td>");
                 sb.Append("<td>");
                 sb.Append("<table style=\"height:323px; width:504px; background-image:removed(../Images/PassBack.jpg)\">");

                 AllEmp.Remove(empsp);
             }

             spcards.InnerHtml = sb.ToString();

         }
