i used this code for printing JPanel contents
all labels and tables in it printing WHITE COLOR. WHY ???
thanks

class JPanelMy extends JPanel implements Printable
{
JPanelMy(MainWindow src)
{
super();
this.src=src;
DateWork dw=new DateWork();
daydate=new JLabel(dw.getDayDate());
titlename=new JLabel();
setLayout(new BoxLayout(this,BoxLayout.Y_AXIS));
setBackground(Color.white);
}
...
public void printData()
{
PrinterJob pj=PrinterJob.getPrinterJob();
pj.setPrintable(this);
pj.printDialog();
try
{
pj.print();
}
catch (PrinterException pe)
{
System.out.println("Printer Exception");
}
}
...
public int print(Graphics g,PageFormat pageFormat,int pageIndex) throws PrinterException
{
Graphics2D g2=(Graphics2D)g;
g2.setColor(Color.black);

int fontHeight=g2.getFontMetrics().getHeight();
System.out.println("fontHeight="+fontHeight);
().getDescent();
//System.out.println("fontDescent="+fontDescent);
