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：
https://www.geek-share.com/detail/2531288721.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：
https://www.geek-share.com/detail/2609246602.html

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id
product-id （PID）：产品id
class             ：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

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：

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">
