ESC/POS热敏打印机安卓库，封装佳博SDK和商米SDK，支持（蓝牙，TCP/IP，USB，商米打印），支持打印html
- 添加 JitPack 到项目根目录的
build.gradle下
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
- 添加依赖到项目中
dependencies {
...
implementation 'com.github.jumperchuck:escpos-android:0.1.0'
}
- 在
AndroidManifest.xml内添加需要的权限
<!--蓝牙-->
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<!--TCP/IP-->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<!--USB-->
<uses-feature android:name="android.hardware.usb.host" />- 在
App入口注册

.id(1) // 标示打印机id
.name("name") // 标示打印机名称
.printWidth(PrintWidth.WIDTH_80.getWidth()) // 设置打印宽度，默认是80mm打印机
.feedBeforeCut((byte) 3) // 设置每次切刀前走纸
.timeout(6000) // 设置连接超时时间
.soTimeout(4000) // 设置读取打印机数据超时时间
.commander(new FactoryCommander()) // 设置打印指令，默认是FactoryCommander，如果确定打印机指令类型，可以传入Esc/Tsc/Cpcl/SunmiCommander以提升首次打印速度

.build();默认是FactoryCommander，此指令器初始化时会按照ESC/TSC/CPCL顺序依此发送检测指令给打印机来判断打印机指令，因此首次打印会有耗时

}使用
EscPosPrinter printer = new GeneralPrinter.Builder(context)
.connection(new MyConnection())
.build();指令器负责通过连接器解析设备返回的数据以及构造发送打印数据
目前仅有Esc/Tsc/Cpcl/Factory/SunmiCommander，EscCommander为防止打印乱码默认启用一票一控模式，只处理了佳博打印机，其他打印机需自行处理 不支持一票一控的打印机可通过添加流控来等待打印机打印完成，数据总大小 / 打印机每秒处理数据大小
