2、雀大按小票宽度设计ASP消费小票打印页
3、添加枯键一个打印按钮，加入onclick= “window.print()”
打印string。给你个类

有两种方法:1.纯html + javascript
-------print.js---------------------------
var hkey_root, hkey_path, hkey_key
hkey_root = "HKEY_CURRENT_USER"
hkey_path = "\\Software\\Microsoft\\Internet Explorer\\PageSetup\\"
//网页打印时清空页眉页脚
function pagesetup_null() {
try {
var RegWsh = new ActiveXObject("WScript.Shell")
hkey_key = "header"
RegWsh.RegWrite(hkey_root + hkey_path + hkey_key, "迟备")
hkey_key = "footer"
RegWsh.RegWrite(hkey_root + hkey_path + hkey_key, "者旦禅")
} catch (e) {
}
}
//网页打印的首尘时恢复页眉页脚为默认值
function pagesetup_default() {
try {
var RegWsh = new ActiveXObject("WScript.Shell")
hkey_key = "header"
RegWsh.RegWrite(hkey_root + hkey_path + hkey_key, "&w&bPage &p of &P")
hkey_key = "footer"
RegWsh.RegWrite(hkey_root + hkey_path + hkey_key, "&u&b&d")
} catch (e) {
}
}
function doPrint(printDiv) {
try {
pagesetup_null()
newwin = window.open("", "newwin", "height=900,width=700,toolbar=no,scrollbars=auto,menubar=no")
newwin.document.body.innerHTML = document.getElementById(printDiv).innerHTML
newwin.window.print()
newwin.window.close()
pagesetup_default()
} catch (e) { }
}
----------------------------------------------------------------------------------------
前面:
<script language=javascript src=printer.js></script>
<div>
DIV1 , do not print me
</div>
<div id="myDiv">
Line2 , need print
</div>
<div>
Line3 , do not print me</div>
<div>
<input type="button" id="bt" onclick="javascript:doPrint('myDiv')" value="Print" />
-----------------------------------------------------------------------------------------------------------
上面的方法简单好用，只需要把打印的内容放在mydiv里面就行了。
但是如果对方访问的时候没有加域，没有权限去修改别人的注册表的话，会出现页眉页脚。
2.用水晶报表做
