No. What I'm saying is to use the code in your current print() method
to draw on a JComponent. In the example below, the method draw() is
used to draw on the JPanel as well as in the print() method to draw on
paper. Needless to say, I have left out printing margins and PageFormat
and all of that.

import java.awt.*;
import java.awt.event.*;
import java.awt.print.*;
import javax.swing.*;

public class test4 extends JPanel implements Printable {
     public test4() {
         setPreferredSize(new Dimension(400,300));
     }

     public void paintComponent(Graphics g) {
         draw(g);
     }

     public void draw(Graphics g) {
         g.drawRect(20,20,360,260);
         g.drawLine(20,20,380,280);
         g.drawLine(20,280,380,20);
     }

     public int print(Graphics g, PageFormat pf, int index) {
         if (index == 0) {
             draw(g);
             return Printable.PAGE_EXISTS;
         } else
             return Printable.NO_SUCH_PAGE;
     }

     public static void main(String[] args) {
         EventQueue.invokeLater(new Runnable() {
             public void run() {
                 JFrame f = new JFrame();
                 f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                 final test4 t4 = new test4();
                 f.add(t4,BorderLayout.CENTER);
                 JButton b = new JButton("Print");
                 b.addActionListener(new ActionListener() {
                     public void actionPerformed(ActionEvent ae) {
                         PrinterJob pj = PrinterJob.getPrinterJob();
                         pj.setPrintable(t4);
                         if (pj.printDialog())
                             try {
                                 pj.print();
                             } catch (PrinterException pe) {
                                 System.out.println(pe);
                             }
                     }
                 });
                 f.add(b,BorderLayout.SOUTH);
                 f.pack();
                 f.setVisible(true);
             }
         });
     }
}
