一、 介绍ScriptX控件
对于B/S架构的项目中，Web打印最是让程序员头痛的技术，在这次项目中运用了第三方控件ScriptX解决了此技术包括各种汇总表，详细清单等等，但最大弊端就是打印的格式是死的，你要打印出怎样的格式必须自己来做，还有就是打印分页，它是按你设置的纸张大小来分的，所以必须人为控制，ScriptX控件所需文件ScriptX.cab。（ScriptX下载地址http://www.meadroid.com/scriptx/freedep.asp ）
打印功能使用：
⑴ 用户在客户端单击“打印”按钮，第一次使用打印会弹出如下对话框
⑵ 单击“是”按钮，此时会把控件ScriptX下载到本机
⑶ 在打印窗口中有大标题、打印条件、打印列表，单击“打印”按钮进入打印浏览界面。
⑷ 单击“Print”按钮，听打印机声音响起。
二、 一个简单的ScriptX控件使用实例
1．界面文件 WebExample.aspx （其中kg.css是界面样式在这里就不介绍了）
<%@ Page language="c#" Codebehind="WebExample.aspx.cs" AutoEventWireup="false" Inherits="WebPrint.WebExample" %>

</tr>
<tr>
<td align="center" valign="top">
<input id="btnPrint" style="WIDTH: 32px; HEIGHT: 19px" οnclick="printResult();" type="button"
size="1" value="打印" name="btnPrint">
</td>
</tr>
</TABLE>
</form>
<script language="javascript">
function printResult()
{
//针对不同模块，设置打印参数
var title = 'ScriptX打印';//报表名称
var orien = 'true';//打印页面方向，true:纵向打印/false横向打印
//参数设置结束
var strURL;
title = escape(title);
//condition = escape(condition);
strURL = 'printContainer2.aspx?title='+title+'&orien='+orien;
window.open(strURL,'printResult','height=600, width=800, top=0, left=50,toolbar=no , menubar=no, scrollbars=yes, resizable=no, location=no, status=no');
}
</script>
</body>
</HTML>
说明：
⑴ <div id="divTableResult" name="divTableResult">和<div id="divChartResult" name="divChartResult"> 是在printContainer2.aspx文件中定义的传值标签，因此必须要有。
⑵ printResult（）方法用来声明传值内容，具体在方法中已说明
2．打印界面 printContainer2.aspx （其中print.css是打印样式就不介绍了）
<%@ Page language="c#" Codebehind="printContainer2.aspx.cs" AutoEventWireup="false" Inherits="WebPrint.printContainer2" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<%
string title = "查询打印";
‘用于title获取标题
if(Request.QueryString["title"].ToString().Trim()!=""){
title = Request.QueryString["title"].ToString().Trim();
}
‘用于orientation获取打印页面方向，true:纵向打印/false横向打印
string orientation = "true";
if(Request.QueryString["orien"].ToString().Trim()!=""){
orientation = Request.QueryString["orien"].ToString().Trim();
}
%>
