Printing AWT Component Without Print Dialog

Please read previous article Printing JTextArea component now find:

try {
text.print();
} catch (PrinterException ex) {
}

replace with:

PrinterJob printJob = PrinterJob.getPrinterJob();
class Job implements Printable {
    @Override
    public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {
        if (pageIndex >= 1) {
            return Printable.NO_SUCH_PAGE;
        }
        Graphics2D g2 = (Graphics2D) graphics;
        g2.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
        text.paint(graphics);
        return Printable.PAGE_EXISTS;
    }
}
printJob.setPrintable(new Job());
try {
  printJob.print();
} catch (Exception ex) {
}

now awt component will print without showing print dialog.

Conclusion:
We can directly print Printable using PrinterJob.print();
