解決方案一：
<HTML><HEAD>
<script language="JavaScript">
var hkey_root,hkey_path,hkey_key
hkey_root="HKEY_CURRENT_USER"
hkey_path="\\Software\\Microsoft\\Internet Explorer\\PageSetup\\"
//設置網(wǎng)頁打印的頁眉頁腳為空
function pagesetup_null()
{
try{
var RegWsh = new ActiveXObject("WScript.Shell")
hkey_key="header"
RegWsh.RegWrite(hkey_root+hkey_path+hkey_key,"")
hkey_key="footer"
RegWsh.RegWrite(hkey_root+hkey_path+hkey_key,"")
}catch(e){}
}
//設置網(wǎng)頁打印的頁眉頁腳為默認值
function pagesetup_default()
{
try{
var RegWsh = new ActiveXObject("WScript.Shell")
hkey_key="header"
RegWsh.RegWrite(hkey_root+hkey_path+hkey_key,"&w&b頁碼，&p/&P")
hkey_key="footer"
RegWsh.RegWrite(hkey_root+hkey_path+hkey_key,"&u&b&d")
}catch(e){}
}
</script>
</HEAD>

<BODY><br/><br/><br/><br/><br/><br/><p align=center>
<input type="button" value="清空頁碼" onclick=pagesetup_null()>
<input type="button" value="恢復頁碼" onclick=pagesetup_default()><br/>
</p></BODY></HTML>
需要將ie安全級別降低，否則創(chuàng)建ActiveXObject對象時會報錯。
解決方案二：
使用第三方免費控件
<head>
<title>打印確認</title>
<style media="print">
.noprint { display: none }
</style>
</head>
<body>
<object id="factory" style="display:none" viewastext classid="clsid:1663ed61-23eb-11d2-b92f-008048fdd814" codebase="http://www./scriptx/ScriptX.cab#Version=5,60,0,360"></object>
<script defer>
function window.onload() {
//factory.printing.paperSize = "A3"
factory.printing.header = ""
factory.printing.footer = ""
factory.printing.portrait = false
idPrint1.disabled = false; // enable UI button
idPrint2.disabled = false;
idPrint3.disabled = false;
idPrint4.disabled = false;
factory.printing.leftMargin = 0.75
factory.printing.topMargin = 1.5
factory.printing.rightMargin = 0.75
factory.printing.bottomMargin = 1.5
}
</script>
<div class=noprint>
<input id="idPrint1" type="button" value="打印本頁"
onclick="factory.printing.Print(false)">
<input id="idPrint2" type="button" value="頁面設置"
onclick="factory.printing.PageSetup()">
<input id="idPrint3" type="button" value="打印預覽"
onclick="factory.printing.Preview()">
<input id="idPrint4" type="button"
onclick="window.close()" value="關閉窗口">
</div>
<br/>
<table width="720" border="0" cellspacing="0" cellpadding="0" align="center" >
<tr>
<td bgcolor="#0099ff">
這里是你要打印的內容，上面的按鈕不會被打印出來<br/>
factory.printing.paperSize = "A3"
</td>
</tr></table></body>
要降低ie的安全級別。

兩種方案的缺點都是要降低ie的安全級別，如果不想降低，就不能在代碼中實現(xiàn)，而要象上面一樣手動更改了。
