Here is my code for displaying the printer dialog and the printing

public void initializeAndPrint() {
    // Create printer selection dialog and open it
    PrintDialog printDialog = new PrintDialog(shell, SWT.APPLICATION_MODAL);
    PrinterData printerData = printDialog.open();
    // Check if OK was pressed
    if (printerData != null) {
      printerData.orientation = pageOrientation;
      // Create new Printer instance
      Printer printer = new Printer(printerData);
      // Open printing task
      if (!printer.startJob("Print Screen")) {
        System.out.println("Starting printer failed");
      } else {
        // Print first page
        if (!printer.startPage()) {
          System.out.println("Printing failed");
        } else {
          printScreen(printer);
        }
      }
    }
  }

private void printScreen(Printer printer) {
    GC gc = new GC(printer);
    float scaleW = 0;
    float scaleH = 0;
    float scale = 1;
    Image swtImage = new Image(display, convertToSWT(imageToBePrinted));
    if (resize) {
      scaleW = new Float((float)printer.getClientArea().width / swtImage.getBounds().width);
      scaleH = new Float((float)printer.getClientArea().height / swtImage.getBounds().height);
      scale = Math.min(scaleW, scaleH);
    } else {
      scaleW = 1;
      scaleH = 1;
    }

Transform transform = new Transform(display);
    transform.scale(scale, scale);
    gc.setTransform(transform);
    gc.drawImage(swtImage, 0, 0);

StringBuilder blder = new StringBuilder(CalendarUtils.getToday().toString());
    if (StringUtils.isNotBlank(build)) {
      blder.append(" Build: " + build);
    }
    Font font = new Font(display, "Arial", 14, SWT.BOLD);
    gc.setFont(font);
    // print today and build dates
    gc.drawString(blder.toString(), 0, swtImage.getBounds().height
            - (gc.stringExtent(blder.toString()).y + 5));
    printer.endPage();
    printer.endJob();
    // Release operating system resources
    font.dispose();
    gc.dispose();
    printer.dispose();
  }

This works fine on windows but not on a Linux machine.
The Printer Selection dialog is displayed and after the user selects a printer, it does not print.
There is no printer job created either.

Don't know if I am doing something wrong or if it is a problem with the SWT Linux jar.
The Linux system uses a different SWT jar, a 64 bit gtk jar.

System configuration:
OS Name: Linux
OS Version: 2.6.24-26-generic
Architecture: amd64

Thanks a lot in advance for your help.
