我正在创建一个可以打印到Brother QL-720NW标签打印机的Android应用程序。我为此创建了一个示例项目。
我已经在libs文件夹中导入了必要的JAR文件,并按照Brother示例项目中的建议设置了打印机设置。但是我一直收到标签不正确的错误。
我已经看过以下帖子ERROR_WRONG_LABEL when trying to print wireless using Android Brother Sdk for label printer 关于类似的问题。
根据Brother手册labelNameIndex应该在我的情况下设置为5.
这是我的清单:
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
这是我的小型演示项目的打印部分:
public void Print(){
Printer myPrinter = new Printer();
PrinterInfo myPrinterInfo = new PrinterInfo();
PrinterStatus myPrinterStatus = new PrinterStatus();
try{
// Retrieve printer informations
myPrinterInfo = myPrinter.getPrinterInfo();
// Set printer informations
myPrinterInfo.printerModel = PrinterInfo.Model.QL_720NW;
myPrinterInfo.port=PrinterInfo.Port.NET;
myPrinterInfo.printMode=PrinterInfo.PrintMode.FIT_TO_PAGE;
myPrinterInfo.paperSize = PrinterInfo.PaperSize.CUSTOM;
myPrinterInfo.ipAddress="192.168.0.193";
myPrinterInfo.macAddress="00:00:00:00:00"; //hidden for security reasons
LabelInfo mLabelInfo = new LabelInfo();
mLabelInfo.labelNameIndex = 5;
mLabelInfo.isAutoCut = true;
mLabelInfo.isEndCut = true;
mLabelInfo.isHalfCut = false;
mLabelInfo.isSpecialTape = false;
myPrinter.setPrinterInfo(myPrinterInfo);
myPrinter.setLabelInfo(mLabelInfo);
// Create bitmap
Bitmap bmap = BitmapFactory.decodeResource(getResources(), R.drawable.printtest);
try{
tView.append("Start" + "\n" );
myPrinter.startCommunication();
PrinterStatus printerStatus = myPrinter.printImage(bmap);
myPrinter.endCommunication();
tView.append(printerStatus.errorCode.toString() + "\n");
}catch(Exception e){
tView.setText(e.toString());
}
}catch(Exception e){
tView.setText(e.toString());
//e.printStackTrace();
}
}
答案 0 :(得分:4)
我遇到了同样的问题,我修复了:
printerInfo.printerModel = PrinterInfo.Model.QL_720NW;
printerInfo.port = PrinterInfo.Port.NET;
printerInfo.ipAddress = "...";
printerInfo.paperSize = PrinterInfo.PaperSize.CUSTOM;
printerInfo.paperPosition = PrinterInfo.Align.CENTER;
printerInfo.orientation = PrinterInfo.Orientation.LANDSCAPE;
printerInfo.labelNameIndex = LabelInfo.QL700.W50.ordinal();
printerInfo.isAutoCut = true;
printerInfo.isCutAtEnd = true;
但是产生差异的一条线是:
printerInfo.labelNameIndex = LabelInfo.QL700.W50.ordinal();
哪里&#34; W50&#34;是纸张类型。您可以在 manual.pdf
中找到该纸张类型ID注意:我们必须使用序数值而不是de Enum值。
