How can I Print a JPanel including all added Components?

Question

Hello dear saviours,
I have a JPanel object which is responsible for displaying a Graph.
I need to Print the Components of this JPanel as close to what they look like to the user as possible.
I thought about casting the JPanel into an Image of some kind, but couldn't find anything but how to add am Image to a JPanel (God damned search engines :-).
But wait, this gets more interesting!
I need to have control over the scale of the Printed matterial.
I want the option to choose between a single page and dividing the drawing the JPanel displays into Multiple-Pages.
In both cases I need full details of all the data (Nodes, Arcs, Text describing the various Nodes and Arcs names or type, etc.).Keeping the sizes of all these components is also important (that means, I don't want the nodes to be tinny-winny and the Fonts to be twice as large as the nodes and so on...).
Attached is the code of the PrintUtillity class I created as an API for printing the JPanel data:
package ild;
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).

g2d.scale(1.0/scaleFactor,1.0/scaleFactor);
// disableDoubleBuffering(componentToBePrinted);
componentToBePrinted.paint(g2d);
enableDoubleBuffering(componentToBePrinted);
return(PAGE_EXISTS);

RepaintManager currentManager = RepaintManager.currentManager(c);

That's a nice utility, but my JPanel gets truncated when printed. Is there a way to print a JPanel in full.
