Class PrintManager

java.lang.Object
  discovery.gui.PrintManager

All Implemented Interfaces:

java.awt.print.Printable

public class PrintManager
extends java.lang.Object
implements java.awt.print.Printable

This class is responsible for printing out task structure, task flow and narrative diagrams. It implements the Printable interface, and provides a static method called 'printComponent' which takes the component to print. It then brings up the standard print dialog to allow the user to setup printing as they would like. Methods are also provided to disable and enable double buffering. Double buffering is disabled before printing to give a much higher quality print with quicker spooling times. This class is based on the PrintUtilities.java class by Marty Hall, which is freely available to use and can be found at: http://www.apl.jhu.edu/~hall/java/Swing-Tutorial/Swing-Tutorial-Printing.html
