xprint库傻瓜式打印
作者：互联网
xprint库是一款傻瓜式连接打印：
1：支持文字
2：支持字体大小和粗细设置
3：支持二维码，图片格式
4：支持表格，表格下划线
5：支持自定义byte数据
6：支持hex和十进制
具体使用
添加arr文件
app moudle build加入：
adnroid{
repositories {
flatDir {
dirs 'libs'
}
}
sourceSets {
main {
jniLibs.srcDirs = ['libs']
}
}
}
dependencies{
compile(name: 'xprint-release', ext: 'aar')
}
全局设置Print连接

public class App extends BaseApp {
private static PrintImpl sPrinterImpl;
@Override
public void onCreate() {
super.onCreate();
sPrinterImpl = new PrintImpl();
}
public static PrintImpl getPrinterImpl() {
return sPrinterImpl;
}
}
在需要的class，添加蓝牙监听和初始化Printer
App.getPrinterImpl().connectPrinter(new IConnectCallback() {
@Override
public void onPrinterConnectSuccess() {
}
@Override
public void onPrinterConnectFailed(int i) {
}
});
App.getPrinterImpl().initPrinter();
打印文字
public class CanvasUtils {
/**
* 画布模版 图片跟文字并行
*
* @param mPrinter -
*/
public static void printCustomImage(PrinterInstance mPrinter, String code, String unit,
String checkDate, String checkOpinion,
String rectificationOpinion, String ename, String unicode, String qrCode) {
mPrinter.setPrinter(PrinterConstants.Command.ALIGN, PrinterConstants.Command.ALIGN_CENTER);
mPrinter.setFont(0, 0, 0, 1, 0);
mPrinter.printText("\n");
mPrinter.printText("测试打印" + "\n");
mPrinter.setFont(0, 0, 0, 0, 0);
mPrinter.setPrinter(PrinterConstants.Command.ALIGN, PrinterConstants.Command.ALIGN_LEFT);
mPrinter.printText(code + "\n");
mPrinter.printText("————————————————" + "\n");
mPrinter.printText(unit + "\n");
mPrinter.printText(checkDate + "\n");
mPrinter.printText(checkOpinion + "\n");
mPrinter.printText(rectificationOpinion + "\n");
mPrinter.printText("————————————————" + "\n");
mPrinter.printText(ename + "\n");
mPrinter.printText("测试打印文字2:" + "\n");
mPrinter.printText(unicode + "\n");
mPrinter.setPrinter(PrinterConstants.Command.ALIGN, PrinterConstants.Command.ALIGN_CENTER);
Barcode barcode = new Barcode(PrinterConstants.BarcodeType.QRCODE, 2, 3, 6,
qrCode);
mPrinter.printBarCode(barcode);
mPrinter.printText("扫码查看检" + "\n\n\n\n");
mPrinter.printText("\n");
}
