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
