Printing in Java to Label Printer

I am having trouble printing to a label printer. The code below prints 4 "labels" on one (Picture of Label Attached).

The code below prints to a brother QL-500 label printer. It prints onto 3.5" by 1.1" labels.

It would also be great if someone could help me better understand the code.

I'm aware of a number of inconsistencies with the PrintDialog doing werid and wonderful things if you try and specify Paper sizes and margins, but honestly, that's a question for another day.

The code I've posted was capable for printing two labels one after the other without issue on my Dymo LabelWriter 400 Turbo

UPDATED Should also mention, I think you were basically missing PageFormat.setPaper

UPDATED with Barbaque BarCode

Print from file example...

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;

    }

}

Printing direct to the Graphics context

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;

    }

}

Last but not least, directly from the "examples" directory of the download

public class PrintingExample

    public static void main(String[] args)
    {
