g.setClip(null) is a documented call to remove clipping during
a repaint ( jdk documentation : Graphics/setClip )
This works fine for display, but the usage of this call when printing
causes following exception:

Exception in thread "main" java.lang.NullPointerException
        at sun.java2d.PeekGraphics.addDrawingRect(PeekGraphics.java:1747)
        at sun.java2d.PeekGraphics.fill(PeekGraphics.java:1464)
        at SimpleViewer.paint(SimpleViewer.java:17)
        at SimpleViewer.print(SimpleViewer.java:41)
        at sun.java2d.RasterPrinterJob.printPage(RasterPrinterJob.java:677)
        at sun.java2d.RasterPrinterJob.print(RasterPrinterJob.java:342)
        at SimpleViewer.main(SimpleViewer.java:74)

The example works fine, if we remove the "setClip(null)" line.
Which other call may be used to remove the clipping ?

Example demonstrating this problem:

import java.util.*;
import java.awt.print.*;
import java.awt.*;
import java.awt.geom.*;
import javax.swing.*;

import java.awt.event.*;

public class SimpleViewer extends JPanel
implements Printable
{
public void paint(Graphics g)
{
//
// Presence of this line forces later exception during printing
//
g.setClip(null);
g.setColor(Color.white);
((Graphics2D)g).fill(new Rectangle(0,0,600,600));

System.out.println("CLIP = "+g.getClipBounds());

g.setColor(Color.red);


g.drawString("TEST STRING",200,200);
}

//
// Printable interface
//
public int print(Graphics g,PageFormat pf,int pageIndex)
throws PrinterException
{
if(pageIndex > 0)
{
return Printable.NO_SUCH_PAGE;
}

paint(g);

return Printable.PAGE_EXISTS;
}

public static void main(String arg[])
{
JFrame f = new JFrame("TEST");

f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
});

     f.getContentPane().setLayout(new BorderLayout());
f.setSize(600,600);

Container container = f.getContentPane();

SimpleViewer sv = new SimpleViewer();
container.add(sv,BorderLayout.CENTER);
f.show();


PrinterJob job = PrinterJob.getPrinterJob();
PageFormat pf = job.defaultPage();
PageFormat printFormat;

if(job.printDialog())
{
printFormat = job.pageDialog(pf);
job.setPrintable(sv,printFormat);
try
{
job.print();
}
catch (PrinterException e)
{
System.out.println(e);
}
}
}
}
