在android热敏打印机中打印阿拉伯字符 [英] Print Arabic characters in android Thermal Printer

问题描述

打印机为 GoojPRT 便携式打印机 PT-210(热敏打印机)

相同的代码在另一台热敏打印机 POS 上工作，但不适用于这台打印机的阿拉伯字符，英文字符很好，但阿拉伯字符显示为中文字符

the same code is work on another thermal printer POS but not work on this printer for Arabic characters the English characters is good but the Arabic characters is shown as chinses characters

尝试添加编码为字符集"UTF-8"并且不适用于阿拉伯字符打印代码:

try to add encoded as charset " UTF-8 " and not working for Arabic characters the code for print :

Button btnPrint=(Button)findViewById(R.id.btnPrint);
        btnPrint.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                Thread t = new Thread() {
                    public void run() {
                        try {
                            OutputStream os = mBluetoothSocket
                                    .getOutputStream();
                            BILL = "ENGLISH" + "\n";
                            BILL =  BILL + "العربية" + "\n";
                            BILL = BILL + "---------------" + "\n";
                            
                            os.write(BILL.getBytes( ));
                        } catch (Exception e) {

                        }
                    }
                };
                t.start();
            }
        });

扫描打印机:

Button btnScan = (Button) findViewById(R.id.btnScan);
        btnScan.setOnClickListener(new View.OnClickListener() {
            public void onClick(View mView) {
                mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
                if (mBluetoothAdapter == null) {
                    Toast.makeText(ActivityTest.this, "Error", Toast.LENGTH_SHORT).show();
                } else {
                    if (!mBluetoothAdapter.isEnabled()) {
                        Intent enableBtIntent = new Intent(
                                BluetoothAdapter.ACTION_REQUEST_ENABLE);
                        startActivityForResult(enableBtIntent,
                                REQUEST_ENABLE_BT);
                    } else {
                        ListPairedDevices();
                        Intent connectIntent = new Intent(ActivityTest.this,
                                DeviceListActivity.class);
                        startActivityForResult(connectIntent,
                                REQUEST_CONNECT_DEVICE);
                    }
                }
            }
        });

印刷样品

我需要打印文本而不是位图或图像

I need to print text not bitmap or image
