因为需要调用打印机封装好的DLL文件，只能在IE下使用ActiveX来调用，直接使用tspl指令来打印。只在前台调用，所以后台什么也不需要，但是客户端需要进行配置，首先要安装打印机驱动，然后注册DLL
本案例相关的dll和整理的文档如下
http://download.csdn.net/detail/u010121228/9861057
在利用ActiveX调用之前，需要注册DLL文件，先把DLL文件夹下的两个 .dll 文件复制到 “C:\windows\system\ ”目录下，
32位系统可直接还用快捷键WIN+R调起并运行 Regsvr32.exe TSCActiveX.dll 指令
64位系统需要运行64位的注册，跳转到当前64位目录下
cd C:\Windows\SysWOW64
并运行 Regsvr32.exe TSCActiveX.dll 指令,如果不能打印，把dll文件放到 C:\Windows\SysWOW64 目录下再次注册。
JSP实现代码如下
