How can I print a single JPanel's contents?

java, printing, swing

Solution

Here is an example to print any Swing component.

public void printComponenet(Component component){
  PrinterJob pj = PrinterJob.getPrinterJob();
  pj.setJobName(" Print Component ");

  pj.setPrintable (new Printable() {    
    public int print(Graphics pg, PageFormat pf, int pageNum){
      if (pageNum > 0){
      return Printable.NO_SUCH_PAGE;
      }

      Graphics2D g2 = (Graphics2D) pg;
      g2.translate(pf.getImageableX(), pf.getImageableY());
      component.paint(g2);
      return Printable.PAGE_EXISTS;
    }
  });
  if (pj.printDialog() == false)
  return;

  try {
        pj.print();
  } catch (PrinterException ex) {
        // handle exception
  }
}

Problem

I have a `JPanel` with two labels with pictures. I need to print these content of the `JPanel`. Please help me out. How can I print only this `JPanel`'s contents, as I also have different components on my `JFrame` but I just need to print this `JPanel`. Thanks.
