对接打印机，首先要有自己的思路。目前主流的小票打印机有蓝牙、wifi、USB接口、网口。我的项目对接的wifi打印接口。
佳博打印机配置IP地址，链接无线（问的商家，买打印机最好找个有耐心的）
下载打印机驱动。（这个感觉是最折腾人的，一定要看好型号，因为一不注意，型号就选错了。配置完发现驱动版本安装错误一定管商家要驱动卸载程序，先卸载再重装别问我怎么知道的
）
引入jar包
pom.xml文件中添加依赖
net.java.dev.jna
打印工具类（下面的DLL文件是佳博提供的支持Windows64位的SDK。这个管商家要寻找适合自己项目环境的）

import com.sun.jna.Native;

//这里现场需要修改
TscLibDll INSTANCE = (TscLibDll) Native.loadLibrary ("D:\\JavaJDK\\TSCLIB.dll",TscLibDll.class);

打印效果
总结：总之通过这次写打印接口需要注意的点：确定调用何种打印接口，一定要找有耐心的商家。佳博打印机提供的SDK还是描述的太模糊了，一上来就让人摸不着头脑，好多资料还是在网上查的。
