我无法打印到标签打印机。下面的代码在一个上打印 4 个“标签”(附加标签的图片)。

下面的代码打印到兄弟 QL-500 标签打印机。它打印在 3.5" x 1.1" 标签上。

如果有人可以帮助我更好地理解代码,那也很棒。

如果您尝试指定纸张尺寸和边距,我知道 PrintDialog 会出现许多奇怪而奇妙的事情,但老实说,这是另一天的问题。

我发布的代码能够在我的 Dymo LabelWriter 400 Turbo 上一个接一个地打印两个标签而不会出现问题

更新 的还应该提到,我认为你基本上是失踪的PageFormat.setPaper

使用 Barbaque 条码更新

从文件示例打印...

Barcode b = BarcodeFactory.createCode128("Hello");
b.setResolution(72);

File f = new File("mybarcode.png");
// Let the barcode image handler do the hard work
BarcodeImageHandler.savePNG(b, f);

.
.
.

public static class PrintFromFile implements Printable {

    @Override
    public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {

        int result = NO_SUCH_PAGE;
        if (pageIndex == 0) {

            graphics.translate((int)pageFormat.getImageableX(), (int)pageFormat.getImageableY());

            result = PAGE_EXISTS;

            try {

                // You may want to rescale the image to better fit the label??
                BufferedImage read = ImageIO.read(new File("mybarcode.png"));
                graphics.drawImage(read, 0, 0, null);

            } catch (IOException ex) {

                ex.printStackTrace();

            }

        }

        return result;

    }

}

直接打印到图形上下文

Barcode b = BarcodeFactory.createCode128("Hello");
b.setResolution(72);

.
.
.

public static class PrintToGraphics implements Printable {

    private Barcode b;

    private PrintToGraphics(Barcode b) {

        this.b = b;

    }

    @Override
    public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {

        int result = NO_SUCH_PAGE;
        if (pageIndex == 0) {

            result = PAGE_EXISTS;

            int x = (int)pageFormat.getImageableX();
            int y = (int)pageFormat.getImageableY();

            int width = (int)pageFormat.getImageableWidth();
            int height = (int)pageFormat.getImageableHeight();

            graphics.translate(x, y);
            try {
                b.draw((Graphics2D)graphics, 0, 0);
            } catch (OutputException ex) {

                ex.printStackTrace();

            }

        }

        return result;

    }

}

最后但同样重要的是,直接从下载的“示例”目录

public class PrintingExample
{

    public static void main(String[] args)
    {
        try
        {
            Barcode b = BarcodeFactory.createCode128("Hello");
            PrinterJob job = PrinterJob.getPrinterJob();
            job.setPrintable(b);
            if (job.printDialog())
            {
                job.print();
            }
        }
        catch (Exception e)
