///////////////////////////////////////////////////////
import java.awt.*;
import java.awt.event.*;
import java.awt.print.*;
public class printbutton extends Panel implements
ActionListener {
public printbutton() {
setBackground(Color.white);
MyButton b = new MyButton();
b.addActionListener(this);
add(b);
}
public void actionPerformed(ActionEvent e) {
System.out.println("action");

public int print(Graphics g, PageFormat pf, int pi)

System.out.println("mybutton print");
if (pi >= 1) {

Graphics2D g2 = (Graphics2D) g;
g2.translate(pf.getImageableX(), pf.getImageableY());
