Java 如何通过蓝牙打印机打印图像

有人知道如何在android中通过蓝牙打印机打印图像吗？。。。我正在使用下面的代码打印字符串，我无法更改字体样式，因此我想打印一张图像

以下是我打印字符串消息的方式：

public void printNa(View v) {
        printFare = amount.getText().toString();
            try {
                PRINTER_MAC_ID = "00:12:F3:19:4D:D8";
                print_message = "This is the sample String";


                    mBTAdapter = BluetoothAdapter.getDefaultAdapter();
                    dialogProgress = new Dialog(Ticketing.this);
                    try {
                        if (mBTAdapter.isDiscovering()){
                            mBTAdapter.cancelDiscovery();
                        }else{
                            mBTAdapter.startDiscovery();
                        }
                } catch (Exception e) {
                    Toast.makeText(this, "Unable to print: " + e, Toast.LENGTH_LONG).show();
                    return;
                }
                    System.out.println("BT Searching status :" + mBTAdapter.isDiscovering());
                    if (mBTAdapter == null) {
                        Toast.makeText(this, "Device has no bluetooth capability",Toast.LENGTH_LONG).show();
                        return;
                    }else{
                        if (!mBTAdapter.isEnabled()) {
                            Intent i = new Intent( BluetoothAdapter.ACTION_REQUEST_ENABLE);
                            startActivityForResult(i, 0);
                        }
                        // Register the BroadcastReceiver
                        IntentFilter filter = new IntentFilter(
                        BluetoothDevice.ACTION_FOUND);
                        registerReceiver(mReceiver, filter);
                    }

                } catch (Exception e) {
                    Toast.makeText(this, "Unable to print: " + e, Toast.LENGTH_LONG).show();
                    return;
                }
        }   
    /********/
    public void printBillToDevice(final String address) {
        mBTAdapter.cancelDiscovery();
        try {

            mBTSocket = (BluetoothSocket) m.invoke(mdevice, 1);
            mBTSocket.connect();

            //  image = "logo";
            //  print_image(Environment.getExternalStorageDirectory().toString() + "/LOGO.png");
        //  byte[] format = { 27, 33, 0 };
        //  byte[] arrayOfByte1 = { 27, 33, 0 };

            int copyPrintIs = Integer.parseInt(copyPrint);
                for(int x = 1; x <= copyPrintIs; x++){
                    OutputStream os = mBTSocket.getOutputStream();
                    os.flush();
                    //os.write(iu_ini_ang_ipiprint.getBytes());

                    SystemClock.sleep(4000);
                }
            copyPrint = "1";
            if (mBTAdapter != null)

                return;
            }
        }
    };

我无法找到一个好的解决方案来改变我的字体风格，所以我决定打印一个图像文件，但我无法找到一个好的解决方案来再次通过热敏打印机打印图像，我使用的是APEX 3打印机。 我是新来的，所以任何帮助都将被感激

对不起，我的英语不好
