java - 使用通常的 Windows 打印对话框而不是 Java 的对话框

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 打印对话框打印时，我收到一条错误消息，提示我要打印的文档格式错误。当我打印到 XPS 文件然后通过 Windows 打印时，一切正常。希望有人能帮助我。

问候

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，我可以从中进行打印。该程序调整图像大小，一切正常。
