Hi,
I am trying to print the text in JTextArea. The printing is done through a class 'PrintUtilities' which can print all 'Component's. But, when tried to print with text that spreads over multiple pages (say 2 pages), I am getting 2 copies of first 41 lines. The text starting from 42 line onwards (2nd page) are not getting printed. Instead I am getting two copies of first 41 lines. i.e in the
following code jTextArea1 contains 80 lines of text. When it got printed I am getting 2 copies of first 41 lines.
Thanking in advance,
Regards,
Unnic.

// the PrintUtilities which will print a Component...

public class PrintUtilities implements Printable {
  private Component componentToBePrinted;
  public static 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);
    try {
        printJob.print();
      } catch(PrinterException pe) {
      }
  }

  public int print(Graphics g, PageFormat pageFormat, int pageIndex) {
// calculating the no. of pages required...
     int width =     this.component.getHeight();
     double imgHeight = pf.getImageableHeight();
     int numpages=  0;
     numpages = (int)(width/imgHeight);
     if(numpages*imgHeight < width)
       numpages++;
    if (pageIndex > numpages) {
      return(NO_SUCH_PAGE);
    } else {
      Graphics2D g2d = (Graphics2D)g;
      g2d.translate(pageFormat.getImageableX(),    
      pageFormat.getImageableY());
      componentToBePrinted.paint(g2d);
      return(PAGE_EXISTS);
    }
  }
// Invoking the print
    PrintUtilities pu = new PrintUtilities(this.jTextArea1);
    pu.print();

You do not appear to be taking notice of the requested pageIndex passed to print().

This question has been abandoned. I will make a recommendation to the moderators on its resolution in a week or two. I appreciate any comments that would help me to make a recommendation.
 
In the absence of responses, I may recommend DELETE unless it is clear to me that it has value as a PAQ. Silence = you don't care

I believe I answered the question.
The page required to be printed is passed to the print method, but the above code ignores it. Thus it prints the 1st page on every page.
