I'm new to JBuilder and are trying to print charts that are already
displayed on the screen using KL Group's jcchart.  I hit the Print menu
item to invoke the following code.  The PrintDialog comes up, but I get
a blank page coming to the printer.  I've included the source that I am
using.  The JCChartComponent is right off the main Frame.

Any help would be appreciated.

public void filePrint_actionPerformed(ActionEvent e)
{
    pj = getToolkit().getPrintJob(this, "Print test", null);
    Graphics pg = pj.getGraphics();
    printComponents(pg);
    pg.dispose();
    pj.end();
}
