android通过USB连接佳博80打印机

GitHub项目地址

条件：1安卓主板上有USB口，2,rom内置了打印驱动

不行就用其他方式或者换主板吧（本人当初使用的工控主板坑得不要不要的）

本文介绍的是使用USB方式

佳博提供两个函数打印

1：只支持单字符不然中文乱码

printString(String string, FONT font, Boolean bold, Boolean underlined, Boolean doubleHeight, Boolean doubleWidth)

2: 打印需要满一行才执行如果不满一行需要在data最后添加 (byte)0x0A

sendData(Vector<Byte> data)
