// This program creates a simple Printer GUI
import javax.swing.JFrame;
public class Printer
{
public static void main( String[] args )
{
PrinterFrame printerFrame = new PrinterFrame();
printerFrame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
printerFrame.setSize( 400, 180 ); // set frame size
printerFrame.setVisible( true ); // display frame
} // end main
} // end class Printer
