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。
