Printing in Java to Label Printer

Printing in Java to Label Printer

Wow, I can't tell you how much I love printing in Java, when it works, it's great...

.

public class PrinterTest {

    public static void main(String[] args) {

        PrinterJob pj = PrinterJob.getPrinterJob();
        if (pj.printDialog()) {
            PageFormat pf = pj.defaultPage();
            Paper paper = pf.getPaper();    
            double width = fromCMToPPI(3.5);
            double height = fromCMToPPI(8.8);    
            paper.setSize(width, height);
            paper.setImageableArea(
                            fromCMToPPI(0.25), 
                            fromCMToPPI(0.5), 
                            width - fromCMToPPI(0.35), 
                            height - fromCMToPPI(1));

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)
    {
        try
        {
            Barcode b = BarcodeFactory.createCode128("Hello");
            PrinterJob job = PrinterJob.getPrinterJob();
            job.setPrintable(b);
            if (job.printDialog())
            {
                job.print();
            }
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }

    }

}

Printing in Java to a label printer that is not default printer

public static void main(String[] args) {
    try
    {
        FileInputStream fis = new FileInputStream("c:\\N0018902726.pdf");
        DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
        DocAttributeSet das = new HashDocAttributeSet(); 
        Doc pdfDoc = new SimpleDoc(fis, flavor, null);
        PrintService printService = PrintServiceLookup.lookupDefaultPrintService(); 
        DocPrintJob printJob = printService.createPrintJob();
        printJob.print(pdfDoc, new HashPrintRequestAttributeSet());
        fis.close();
    }
    catch (Exception e) {
        System.out.println("EXCEPTIOn : " +e.getMessage());

    }
}

How can I print a label with FBPL and Java on Brother Label Printer (TD-4750TNWB) in a Linux environment?

Using java you will have to write the hex representation of the commands you want to send.

Then from java you will need to call lpr -P Brother-TD4750 -l brotherHexVersion.txt
