Changing Printer Ink Colour

[henri henri]

Below is my standard print module. It prints the film titles seen in red located within a JTextArea. The print comes out as the same colour red I have specified in my JTextArea. In order to save on coloured ink, I would like to have it print out in black. I experimented with the print class, but failed to find out where to insert code that would give me a black ink printout.

  public class PrintUtilities implements Printable {
  private Component componentToBePrinted;
  
  public static final void printComponent(Component c) {
    new PrintUtilities(c).print();
  }
  
  public PrintUtilities(Component componentToBePrinted) {
    this.componentToBePrinted = componentToBePrinted;
  }
  
  public void print() {
    PrinterJob printJob = PrinterJob.getPrinterJob();
    printJob.setPrintable(this);
    if(printJob.printDialog())
      try {
        printJob.print();
     } catch(PrinterException pe) {
          JFrame fr = new JFrame();
          JOptionPane.showMessageDialog(fr, "Il est impossible d'imprimer la page!",
          "Avertissement!",  JOptionPane.WARNING_MESSAGE);
      }
  }
  
  public int print(Graphics gr, PageFormat pf, int pageIndex) {
    int response = Printable.NO_SUCH_PAGE;
    Graphics2D g2 = (Graphics2D) gr;
    g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                                                   RenderingHints.VALUE_ANTIALIAS_ON);
    this.disableDoubleBuffering(componentToBePrinted);
    Dimension d = componentToBePrinted.getSize(); 
    double panelWidth = d.width; 
    double panelHeight = d.height;
    double pageHeight = pf.getImageableHeight();
    double pageWidth = pf.getImageableWidth(); 
    double scale = pageWidth / panelWidth;
    int totalNumPages = (int) Math.ceil(scale * panelHeight / pageHeight);
       if(pageIndex == totalNumPages) {
         response = Printable.NO_SUCH_PAGE;
    } else {
         g2.translate(pf.getImageableX(), pf.getImageableY());
         g2.translate(0f, - pageIndex * pageHeight);
         g2.scale(scale, scale);
         componentToBePrinted.paint(g2);
         this.enableDoubleBuffering(componentToBePrinted);
         response = Printable.PAGE_EXISTS;
    }
    return response;
  }
  
  public static void disableDoubleBuffering(Component c) {
    RepaintManager currentManager = RepaintManager.currentManager(c);
    currentManager.setDoubleBufferingEnabled(false);
  }
  
  public static void enableDoubleBuffering(Component c) {
    RepaintManager currentManager = RepaintManager.currentManager(c);
    currentManager.setDoubleBufferingEnabled(true);
  }
}

Very nice screenshot!! Deserves a bottle of red ink!

Can you select "PRINT IN B&W option " in your printJob.printDialog()-dialog?

or

Did you try:
componentToBePrinted.getGraphics().setColor(Color.black);
componentToBePrinted.paint(g2);
Probably will not succeed?

Just curious....
