Printing AWT From Applet

[Patricia Fulk]

Hello all,
I am trying to print a panel from an applet, but it isn't working. All I get is a blank page. I am using the print utility that someone had suggested to someone else on this site. I am trying to call the utility with the following:
PrintUtilities.printComponent(aPanel);
Where aPanel is a panel with different awt components on it, i.e. TextArea, TextField, Label, etc.
Can someone tell me what I am doing wrong?
Thanks for the help in advance,
Trish

The print utility code is as follows:

import java.awt.*;
import javax.swing.*;
import java.awt.print.*;
/** A simple utility class that lets you very simply print
* an arbitrary component. Just pass the component to the
* PrintUtilities.printComponent. The component you want to
* print doesn't need a print method and doesn't have to
* implement any interface or do anything special at all.
* <P>
* If you are going to be printing many times, it is marginally more
* efficient to first do the following:
* <PRE>
* PrintUtilities printHelper = new PrintUtilities(theComponent);
* </PRE>
* then later do printHelper.print(). But this is a very tiny
* difference, so in most cases just do the simpler
* PrintUtilities.printComponent(componentToBePrinted).
