Android(安卓)热敏打印机开发(蓝牙)

前言
由于自己工作原因，涉及到热敏打印机开发，因此自己写了一套热敏打印机SDK，目前暂时只支持蓝牙打印
我生成了jar包的形式，方便大家使用。里面代码的实现原理现在暂无时间去讲解，主要以如何使用为主。后面将会开源，现在没时间。大家可以关注我，后期将会更新
SDK
源码地址

注意事项
目前只适配了蓝牙打印机，58型号的，后期会跟上。。。80的也可以打印就是了
已完成功能
扫描蓝牙
打印一行，打印一行两列，打印一行三列，打印图片，打印条形码。。。
未完成功能
打印二维码(目前需要打印的只能通过图片打印方式进行，貌似58是不支持打印二维码的)
效果图
步骤
如何导入jar包我就不说了。权限
