首先建立一个模板页：
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="PrintMasterPage.master.cs"
Inherits="PrintMasterPage" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head id="Head1" runat="server"> <title></title> <object id='WebBrowser' width='0' height='0' classid='CLSID:8856F961-340A-11D0-A96B-00C04FD705A2'> </object> <link rel="stylesheet" href="css/show.css" type="text/css" /><script language="javascript" type="text/javascript">
//获取单个对象function getObj(id)
{
return document.getElementById(id);
}//获取对象组function getObjs(name){ return document.getElementsByTagName(name);}//打印文档function printDoc(){ var objs=getObjs('div'); var length=objs.length; for(var i=0;i<length;i++) { if(objs[i].print==1) { p=objs[i].parentNode; p.style.visibility='visible'; if(p.childNodes.length>1) { for(var j=0;j<p.childNodes.length;j++) { if(p.childNodes[j].print!=1&&p.childNodes[j].style!=undefined) { p.childNodes[j].style.visibility='hidden'; } } } objs[i].visibility='visible'; } } PageSetup_Null(); //InitPrint(); getObj('WebBrowser').ExecWB(7,1);}</script><script language="JavaScript" type="text/javascript"> var HKEY_Root,HKEY_Path,HKEY_Key; HKEY_Root="HKEY_CURRENT_USER"; HKEY_Path="\\Software\\Microsoft\\Internet Explorer\\PageSetup\\"; //设置网页打印的页眉页脚为空 function PageSetup_Null() { try { var Wsh=new ActiveXObject("WScript.Shell"); HKEY_Key="header"; Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,""); HKEY_Key="footer"; Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,""); HKEY_Key="margin_bottom"; Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"2"); HKEY_Key="margin_left"; Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"2"); HKEY_Key="margin_right"; Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"2"); HKEY_Key="margin_top"; Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"2"); } catch(e){ //alert(e); } } //设置网页打印的页眉页脚为默认值 function PageSetup_Default() { try { var Wsh=new ActiveXObject("WScript.Shell"); HKEY_Key="header"; Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"&w&b页码,&p/&P"); HKEY_Key="footer"; Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"&u&b&d"); } catch(e){} } </script><style type="text/css" media="print">body{visibility:hidden;}.print{visibility:visible;}</style><style type="text/css" media="screen">body{visibility:visible; margin-top: 0px; margin-left:0px;}.control{ margin: 0px; padding: 0px; width: 590px;}</style></head><body> <form id="form1" runat="server"> <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server"> </asp:ContentPlaceHolder> <div align="center"> <table width="100%"> <tr> <td align="center"> <input id="btnPrint" type="button" value=" 打 印 " onclick="javascript:printDoc();" class="button" /> <input type="button" id="btnSet" class="button" value="页面设置" onclick="javascript:document.all.WebBrowser.ExecWB(8,1)" /> <input type="button" id="btnClose" onclick="javascript:document.all.WebBrowser.ExecWB(45,1);" value=" 关 闭 " class="button" /> </td> </tr> </table> </div> </form></body></html>
然后在子页面中设置给要打印的DIV添加一个（print="1"）的属性就可以了。
