androidUSB通信——打印机

本文主要解决一下几个问题：
- usb的基本通信
- usb的基本通信打印文字
- 使用jar包打印一个订单信息

一、usb基础

Android 支持各种 USB 外围设备，通过两种模式来支持 Android USB 外设（实现了 Android 外设协议的硬件）： USB 外设模式和 USB 主机模式。在 USB 外设模式下，外部 USB 硬件（装有 Android 的设备要连接的外部设备）充当 USB 主机。
关于usb的介绍可以查看：
http://www.cnblogs.com/over140/archive/2011/11/03/2234258.html
我们这里面使用的是 usb host方式，关于usb host的介绍可以查看官网文档，也可以查看：
http://blog.csdn.net/yylooker2008/article/details/24378991

二、创建基本usb通信

主要涉及到以下的文件：
- AndroidManifest.xml 清单文件
- UsbDemoActivity.java
- qwm_usb_xml.xml 这个文件放在 res/xml的下面，用来过滤设备

2.1qwm_usb_xml.xml说明

这个文件放在 res/xml的下面，用来过滤设备，满足的设备将会被过滤出来。

<?xml version="1.0" encoding="utf-8"?>
<resources><usb-device vendor-id="1234" product-id="5678"/><usb-device vendor-id="1155" product-id="22304" />
</resources><!--参数说明：vendor-id  （VID）：产商idproduct-id （PID）：产品idclass             ：类subclass          ：子类protocol          ：协议
-->

2.2AndroidManifest.xml清单文件配置

这里主要用来申明usb的相关信息

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.qwm.qwmprinterdemo"><!--声明使用usb--><uses-feature android:name="android.hardware.usb.host"></uses-feature><application
        android:allowBackup="true"android:icon="@mipmap/ic_launcher"android:label="@string/app_name"android:supportsRtl="true"android:theme="@style/AppTheme"><activity
            android:name=".MainActivity"android:label="@string/app_name"android:theme="@style/AppTheme.NoActionBar"></activity><activity
            android:name=".UsbDemoActivity"android:label="@string/title_activity_usb_demo"android:theme="@style/AppTheme.NoActionBar"><intent-filter><!--usb设备的动作--><action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" /><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter><!-- android设备的信息过滤--><meta-data android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"android:resource="@xml/qwm_usb_xml" ></meta-data></activity></application>
</manifest>

2.3UsbDemoActivity.java usb的操作类

这个类用来操作usb,我们主要按一下几个步骤来操作：
- 1.创建UsbManager
- 2.获取满足的设备
- 3.获取满足设备中的“接口”
- 4.获取接口的端点(获取设备endpoint)
- 5.连接设备
- 6.发送数据

//                    sb.append("\n\n");if (device.getVendorId() == 1155 && device.getProductId() == 22304) {myUsbDevice = device; // 获取USBDevice}}usbDevicesTv.setText(sb.toString());}/*** usb设备的信息* @param device* @return*/public String devicesString(UsbDevice device){StringBuilder builder = new StringBuilder("UsbDevice\nName=" + device.getDeviceName() +"\nVendorId=" + device.getVendorId() + "\nProductId=" + device.getProductId() +"\nmClass=" + device.getClass() + "\nmSubclass=" + device.getDeviceSubclass() +"\nmProtocol=" + device.getDeviceProtocol() + "\nmManufacturerName=" +"\nmSerialNumber=" +"\n\n");return builder.toString();}/*** 获取设备的接口*/private void getDeviceInterface() {if(myUsbDevice!=null){Log.i(TAG,"interfaceCounts : "+myUsbDevice.getInterfaceCount());usbInterface = myUsbDevice.getInterface(0);System.out.println("成功获得设备接口:" + usbInterface.getId());}}/*** 分配端点，IN | OUT，即输入输出；可以通过判断*/private void assignEndpoint() {if(usbInterface!=null){for (int i = 0; i < usbInterface.getEndpointCount(); i++) {UsbEndpoint ep = usbInterface.getEndpoint(i);switch (ep.getType()){case UsbConstants.USB_ENDPOINT_XFER_BULK://块if(UsbConstants.USB_DIR_OUT==ep.getDirection()){//输出epBulkOut = ep;System.out.println("Find the BulkEndpointOut," + "index:" + i + "," + "使用端点号："+ epBulkOut.getEndpointNumber());}else{epBulkIn = ep;System.out .println("Find the BulkEndpointIn:" + "index:" + i+ "," + "使用端点号："+ epBulkIn.getEndpointNumber());}break;case UsbConstants.USB_ENDPOINT_XFER_CONTROL://控制epControl = ep;System.out.println("find the ControlEndPoint:" + "index:" + i+ "," + epControl.getEndpointNumber());break;case UsbConstants.USB_ENDPOINT_XFER_INT://中断if (ep.getDirection() == UsbConstants.USB_DIR_OUT) {//输出epIntEndpointOut = ep;System.out.println("find the InterruptEndpointOut:" + "index:" + i + ","  + epIntEndpointOut.getEndpointNumber());}if (ep.getDirection() == UsbConstants.USB_DIR_IN) {epIntEndpointIn = ep;System.out.println("find the InterruptEndpointIn:" + "index:" + i + ","+ epIntEndpointIn.getEndpointNumber());}break;default:break;}}}}/*** 连接设备*/public void openDevice() {if(usbInterface!=null){//接口是否为null// 在open前判断是否有连接权限；对于连接权限可以静态分配，也可以动态分配权限UsbDeviceConnection conn = null;if(usbManager.hasPermission(myUsbDevice)){//有权限，那么打开conn = usbManager.openDevice(myUsbDevice);}if(null==conn){Toast.makeText(this,"不能连接到设备",Toast.LENGTH_SHORT).show();return;}//打开设备if(conn.claimInterface(usbInterface,true)){myDeviceConnection = conn;if (myDeviceConnection != null)// 到此你的android设备已经连上zigbee设备System.out.println("open设备成功！");final String mySerial = myDeviceConnection.getSerial();System.out.println("设备serial number：" + mySerial);} else {System.out.println("无法打开连接通道。");Toast.makeText(this,"无法打开连接通道。",Toast.LENGTH_SHORT).show();conn.close();}}}/*** 发送数据* @param buffer*/public void sendMessageToPoint(byte[] buffer) {if(myDeviceConnection.bulkTransfer(epBulkOut,buffer,buffer.length,0) >= 0){//0 或者正数表示成功Toast.makeText(this,"发送成功",Toast.LENGTH_SHORT).show();}else{Toast.makeText(this,"发送失败的",Toast.LENGTH_SHORT).show();}}
}

三、使用jar包打印

jar就是把上面打印的指令进行了封装。但是我们使用的是usb通信，所以上面的usb配置步骤还是需要的。
主要涉及以下几个文件：
- AndroidManifest.xml 清单文件配置
- MainActivity.java 打印操作界面
- PrintTerUtils.java 打印工具类
- regoPrintLibV3.0.05.jar 打印的jar包

3.1 regoPrintLibV3.0.05.jar包中 regoPrinter 类的主要方法说明

regoPrinter打印机操作类主要方法如下：

方法	说明
CON_PageStart	开启页模式
ASCII_PrintString	打印字符
ASCII_CtrlPrintCRLF	换行
DRAW_SetFillMode	画图填充方式
DRAW_SetLineWidth	画图线的宽度
DRAW_PrintRectangle	画矩形
ASCII_CtrlReset	重置
ASCII_CtrlCutPaper	切纸
CON_PageEnd	结束页模式

切纸的方法调用：

  //切纸功能printer.CON_PageStart(myState, false, 0, 0);printer.ASCII_CtrlCutPaper(myState, 30, 0);

3.1AndroidManifest.xml配置说明

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.qwm.qwmprinterdemo"><!--声明使用usb--><uses-feature android:name="android.hardware.usb.host"></uses-feature><application

</manifest>

3.2 PrintTerUtils.java 打印工具类
