热敏打印机中文字符编码encoding参考表和android打印模块

首先，你打印测试页，查看打印机默认支持哪种字符集，我这里写的是cp936

然后参照下表

https://docs.oracle.com/javase/8/docs/technotes/guides/intl/encoding.doc.html

打印模块，用的是

https://github.com/DantSu/ESCPOS-ThermalPrinter-Android

下载aar引用

https://jitpack.io/com/github/anggastudio/Printama/0.9.7/Printama-0.9.7.aar

全部引用

implementation fileTree(dir: 'libs', include: ['*.aar'])

或者指定引用

implementation files('libs/Printama-0.9.7.aar')

打印代码示例

public void printMe() throws EscPosConnectionException, EscPosParserException, EscPosEncodingException, EscPosBarcodeException {
        //gb18030 or cp936 简体中文 cp932 日文
        BluetoothConnection printerConn=BluetoothPrintersConnections.selectFirstPaired();
        EscPosPrinter printer = new EscPosPrinter(printerConn,
                203,
                48f,
                32,
                new EscPosCharsetEncoding("cp936", 0));

        printer.printFormattedText(
            //"[C]<img>" + PrinterTextParserImg.bitmapToHexadecimalString(printer, App.getContext().getApplicationContext().getResources().getDrawableForDensity(R.drawable.ic_launcher_foreground, DisplayMetrics.DENSITY_MEDIUM))+"</img>\n" +
            //"[L]\n" +
            "[C]<u><font size='big'>ORDER N°045</font></u>\n" +
