在 Java 中打印到标签打印机

Question

我在标签打印机上打印时遇到了问题。下面的代码在一个上打印4个“标签”（附标签图片）。

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

如果有人能帮我更好地理解代码，那也太好了。

我有一个类似的代码，但无法使东芝便携式打印机在TPCL模式下打印，我的代码工作正常，但只有当打印机在ESC/POS模式下。我的打印机是东芝B-EP4-DL

如果你试着指定纸张大小和页边距，我意识到PrintDialog有一些不一致的地方，但老实说，这是另一个问题。

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，没有问题。

更新还应该提到，我认为你基本上错过了PageFormat.setPaper

更新了烧烤条形码

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();

            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;

    }

}

最后但并非最不重要的一点是，直接从“示例”目录下载

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)
        {
            e.printStackTrace();
        }

    }

}
