Question

如何使用标准Windows“打印”对话框而不是“Java对话框”进行打印。我在使用标签打印机打印条形码时遇到问题。当我通过Java-Print对话框打印时，我收到一个错误，告诉我我要打印的文档格式是错误的。当我打印到XPS文件然后通过Windows打印时，一切都很完美。希望有人能帮助我。

try {
    Code128Bean bean = new Code128Bean();
    final int dpi = 150;

    //Configure the barcode generator
    bean.setModuleWidth(UnitConv.in2mm(2.0f / dpi)); //makes the narrow bar width exactly one pixel
    bean.setBarHeight(10);
    bean.doQuietZone(false);

    //Open output file
    File outputFile = new File("out.png");
    OutputStream out;
    out = new FileOutputStream(outputFile);

    //Set up the canvas provider for monochrome PNG output
    BitmapCanvasProvider canvas = new BitmapCanvasProvider(out, "image/x-png", dpi, BufferedImage.TYPE_BYTE_BINARY, false, 90);

    // 200x 10

    //Generate the barcode
    bean.generateBarcode(canvas, barcode);

    //Signal end of generation
    canvas.finish();
    out.close();


    paintComponent(labelArtikelbezeichnung.getText());
    String working_dir = System.getProperty("user.dir");
    try {
        Runtime rt = Runtime.getRuntime();
        String command = "C:\\WINDOWS\\system32\\rundll32.exe C:\\WINDOWS\\system32\\shimgvw.dll,ImageView_Fullscreen " + "" + working_dir + "\\out.png";
        System.out.println(command);
        Process pr = rt.exec(command);

        BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream()));
        String line=null;
        while((line=input.readLine()) != null) {
            System.out.println(line);
        }

        int exitVal = pr.waitFor();
        System.out.println("Exited with error code "+exitVal);

    } catch(Exception e) {
        System.out.println(e.toString());
        e.printStackTrace();
    }
} catch (IOException ex) {
    System.out.println("Error creating the Barcode");
}

程序打开Windows打印和传真对话框，我可以从中打印。该程序调整图像大小，一切都很完美。

这可能是标签打印机本身产生的错误，而不是Java。尝试使用Java将数据写入XPS文件，然后从Java打印。

使用通常的Windows打印对话框而不是Java的对话框
