URGENT.PLEASE HELP!!!Print graphics problem

Question

Hi,
Please help me in this one.I try to print Graphics but I can't.
1) Spooling lasts too long
2) After spooling , printing does not continue
3) An empty page is printed instead
4) Printing process takes about 60 Mbytes of RAM to perform (??!!!)
Here is my code :
class MyDrawings extends JPanel implements Printable
private Image offImage;
private Graphics2D offGraphics2D;
private init_graphics()
offImage = this.createImage ( 200,200 );
offGraphics2D = (Graphics2D)offImage.getGraphics();
public void paint(Graphics g)
Graphics2D g2 = (Graphics2D)g;
if (offGraphics2D == null) return;
// Paint the backgroung
offGraphics2D.setColor(Color.black)
offGraphics2D.fillRect(0,0,getWidth(),getHeight());
g2.drawImage(offImage,0,0,null);
void jButton3_actionPerformed(ActionEvent e) // 'Print' Button was pressed
PrinterJob pj = PrinterJob.getPrinterJob();
RepaintManager.currentManager(this).setDoubleBufferingEnabled(false);
if (pj.printDialog())
try
pj.setPrintable(this);
pj.print();
catch (Exception PrintException) {PrintException.printStackTrace();}
RepaintManager.currentManager(this).setDoubleBufferingEnabled(true);
public int print(Graphics g, PageFormat pf, int pageIndex)
if (pageIndex != 0 )
return NO_SUCH_PAGE;
Graphics2D g2 = (Graphics2D) g;
double wscale = pf.getImageableWidth() / this.getWidth();
double hscale = pf.getImageableHeight()/ this.getHeight();
g2.scale(wscale, hscale);
g2.translate(pf.getImageableX(), pf.getImageableY());
paint(g2);
return PAGE_EXISTS;
I use JDK 1.4.0 and Win2000.
Thank you so much for your help!

Change the construnctor and the paint as follow
class MyDrawings extends JPanel implements Printable
     private Image      offImage;
     private Graphics2D offGraphics2D;
private MyDrawings()
public void paint(Graphics g)
     Graphics2D g2 = (Graphics2D)g;
     if (offImage == null)
          offImage      = this.createImage(getWidth(),getHeight());
          offGraphics2D = (Graphics2D)offImage.getGraphics();
     offGraphics2D.setColor(Color.black);
     offGraphics2D.fillRect(0,0,getWidth(),getHeight());
     g2.drawImage(offImage,0,0,null);
void jButton3_actionPerformed(ActionEvent e) // 'Print' Button was pressed
.
