Question

I use Zebra QL320 plus printer. Fonts was loaded from Win7(sys. encoding CP1251).
When I send text from Android via bluetooth to printer in russian lng:

! 0 200 200 200 1
ENCODING UTF-8
TEXT 14 0 20 80 Привет мир
PRINT

I have in result something like this:

Привет мир

How I can fix this?

Answer 1

Here is working example:

public void bluetoothSendData(String text){
    bluetooth_adapter.cancelDiscovery();
    if (socket_connected) {
        try {
            OutputStream o_stream = socket.getOutputStream();               
            o_stream.write(decodeText(text, "CP1251"));
            Log.i("emi", "Data was sended.");
        } catch (IOException e) {
            bluetoothCloseConnection();
            Log.i("emi", "Send data error: " + e);
        }
    } else {
        Log.i("emi", "Bluetooth device not connected.");
    }
}

private byte[] decodeText(String text, String encoding) throws CharacterCodingException, UnsupportedEncodingException{
    Charset charset = Charset.forName(encoding);
    CharsetDecoder decoder = charset.newDecoder();
    CharsetEncoder encoder = charset.newEncoder();
    ByteBuffer bbuf = encoder.encode(CharBuffer.wrap(text));
    CharBuffer cbuf = decoder.decode(bbuf);
    String s = cbuf.toString();
    return s.getBytes(encoding);
}

How I understend, this examle will be work in Fonts what was loaded from OS with encoding CP1251.
