Class PrintFrame generates a frame that has a PrintPanel embedded into its
content pane. The frame has a menu with only one item 'Print'. The listener
for this item is implemented by defining actionPerformed . When the item is
selected, a print job for the embedded panel is generated and started as described
in Section 19.2. The frame also has main method which launches the application.
