Android蓝牙打印机功能开发（提供完整Demo）

蓝牙便携式打印机的种类繁多，支持的打印格式也不尽相同。按照指令集可划分为：ESC指令集、CPCL指令集、TSC指令集，实现原理基本相同，我这里以找了个公司的便携式打印机为例，下面是演示流程。先蓝牙搜索配对，发送打印指令，指令结果反馈。

**目录**

一、检测蓝牙是否开启，然后搜索

二、连接蓝牙打印机

三、开启线程，发送打印指令

四、打印指令结果反馈

五、便携式打印机操作指令

**代码已实现，先上打印效果图：**

##  **一、检测蓝牙是否开启，然后搜索** ##

private void initBluetooth() {
            mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
            if (mBluetoothAdapter == null) {
                toast("该设备不支持蓝牙");
            } else {
                //检测蓝牙未开启，主动开启
                if (!mBluetoothAdapter.isEnabled()) {
                    Intent enableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
                    startActivityForResult(enableIntent, REQUEST_ENABLE_BT);
                } else {
                    manager = (LocationManager) this.getSystemService(LOCATION_SERVICE);
                    //检测定位是否开启
                    if (EasyPermissions.hasPermissions(this, Manifest.permission.ACCESS_FINE_LOCATION)) {
                        if ((Build.VERSION.SDK_INT >= 29) && !manager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
                            gpsDialog();
                        } else {
                            searchBlueTooth();
                        }
                    } else {
                        gpsDialog();
                    }
                }
            }
        }

## **二、连接蓝牙打印机** ##

private void connectBluetooth(String mac) {
            showLoading();
            //连接打印机
            PrinterDevices blueTooth = new PrinterDevices.Build()
                    .setContext(this)
                    .setConnMethod(ConnMethod.BLUETOOTH)
                    .setMacAddress(mac)
                    .setCommand(Command.CPCL)
                    .setCallbackListener(this)
                    .build();
            // TODO 连接设备
            Printer.connect(blueTooth);
        }

## 三、开启线程，发送打印指令 ##

public void startPrintDate() {
            if(mTotal<1){
                toast("打印模板数据为空");
                return;
            }
            ThreadPoolManager.getInstance().addTask(new Runnable() {
                @Override
                public void run() {
                    try {
                        if (Printer.getPortManager() == null) {
                            sendHandlerMsg(WHAT_PRINT_NOT_CONNECTED,0);
                            return;
                        }
                        //****************** 查询状态********************
                        Command command = Printer.getPortManager().getCommand();
                        int status = Printer.getPrinterState(command);
                        if (status != 0) {
                            //打印机异常状态
                            Log.e("OkGo-print","---------打印机状态status="+status+"------mIndex="+mIndex);
                            sendHandlerMsg(WHAT_PRINT_STATUS,status);
                            return;
                        }
                        //Thread.sleep(1500);
                        //******************调用打印*********************
                        Vector<Byte> data;
                        if(mIndex<mTotal){
                            if(mPrintData.get(mIndex).getType()==1){
                                //客户联标签
                                data =PrintContent.getCustomerTag(PrintMainActivity.this,mPrintData.get(mIndex));
                            }else {
                                //货物标签
                                data =PrintContent.getGoodsTag(PrintMainActivity.this, mPrintData.get(mIndex),mIndex,mTotal-1 );
                            }
                            boolean result = Printer.getPortManager().writeDataImmediately(data);
                            //发送结果
                            Log.e("OkGo-print","---------打印进度mIndex="+mIndex+"-----"+result);
                            sendHandlerMsg(WHAT_PRINT_RESULT,result?0:1);
                        }
                    } catch (Exception e) {
                        //发送异常
                        Log.e("OkGo-print","---------打印出现异常");
                        sendHandlerMsg(WHAT_PRINT_FAIL,0);
                    }
                }
            });
        }

## 四、打印指令结果反馈 ##

打印结果：成功或失败，对应错误码

private Handler mHandler = new Handler() {
            @Override
            public void handleMessage(Message msg) {
                switch (msg.what) {
                    //打印机状态
                    case WHAT_PRINT_STATUS:
                        if(msg.arg1==-1){//获取状态失败
                            toast("打印机状态获取失败，请检查打印机是否缺纸或开盖");
                        }else if(msg.arg1==1){//系统走纸
                            if(isShowToast){
                                toast("状态走纸、打印");
                                isShowToast=false;
                            }
                            //startPrintDate();
                            if(tvPrint!=null){
                                tvPrint.postDelayed(new Runnable() {
                                    @Override
                                    public void run() {
                                        //出现异常，继续调用打印
                                        startPrintDate();
                                    }
                                },2000);
                            }
                        }else if(msg.arg1==-2){//状态缺纸
                            toast("状态缺纸");
                        }else if(msg.arg1==-3){//状态开盖
                            toast("状态开盖");
                        }else if(msg.arg1==-4){//状态过热
                            toast("状态过热");
                        }else if(msg.arg1==0){//正常
                            toast("状态正常");
                        }
                        break;
                    //打印结果
                    case WHAT_PRINT_RESULT:
                        if(msg.arg1==0){
                            if(mIndex==mTotal-1){
                                isShowToast=true;
                                toast("打印完成");
                            }else {
                                //打印下一条
                                mIndex++;
                                startPrintDate();
                            }
                           // tvPrintNumber.setText("打印进度: "+(mCurrentIndex+1)+"/"+mPrintData.size());
                        }else {
                            toast("打印指令发送失败");
                        }
                        break;
                        //打印失败
                    case WHAT_PRINT_FAIL:
                        if(msg.arg1==0){
                            toast("打印失败");
                        }
                        break;
                    case WHAT_PRINT_NOT_CONNECTED:
                        if(msg.arg1==0){
                            toast("打印机未连接");
                            initBluetooth();
                        }
                        break;
                    default:
                        break;
                }
            }
        };

## 五、便携式打印机操作指令 ##
