I tried the following code AWT but at runtime shows multiple print dialogs repeatedly....

package printerjob;

import java.awt.BasicStroke;

import java.awt.Frame;

import java.awt.Graphics;

import java.awt.Graphics2D;

import java.awt.event.WindowAdapter;

import java.awt.print.PageFormat;

import java.awt.print.Printable;

import java.awt.print.PrinterException;

import java.awt.print.PrinterJob;

/** * * @author pragX */ public class FramePrinterJob extends Frame implements Printable{

public void start(){
    add(button);
}
@Override
public void paint(Graphics graphics){
    PrinterJob printerJob=PrinterJob.getPrinterJob();
    printerJob.setPrintable(this);
    if(printerJob.printDialog()){
        try{
            printerJob.print();
        }catch(PrinterException printerException){
            //printerException.printStackTrace();
            System.out.println("Error Printing." + printerException);
        }
    }
}

public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {
    //throw new UnsupportedOperationException("Not supported yet.");
    if(pageIndex>=1){
        return Printable.NO_SUCH_PAGE;
    }

    graphics.translate((int) pageFormat.getImageableX(), (int)pageFormat.getImageableY());
    Graphics2D graphics2D=(Graphics2D)graphics;
    graphics2D.setStroke(new BasicStroke(4f));

    graphics2D.drawLine(20, 20, 20, 120);
    graphics2D.drawLine(40, 20, 40, 120);
    graphics2D.drawLine(20, 70, 40, 70);
    graphics2D.drawLine(60, 70, 60, 120);
    graphics2D.drawLine(60, 40, 60, 45);

    return Printable.PAGE_EXISTS;
}


public static void main(String args[]){
    Frame frame=new FramePrinterJob();
    frame.addWindowListener(new WindowAdapter() { public void windowClosing(){System.exit(0);}});
    frame.setSize(300,400);
    frame.setVisible(true);
}

}
