Cant flush printing queue

Question

Hello guys,
Im developing a POS application on NB IDE 6.1 with JDK 1.6 on Swing
The problem im facing at the moment is that once I try to print a ticket (or the exact word is receipt?), it works perfectly but after that one, the next tickets will show the information of the last ones.
I dont know if Im explaining myself well... if I print the first ticket, I see the ticket printed correctly. But when Im going to print another one, I get the last ticket printed and the new one.
For this matter Im using the Printable Interface.
What I do is this:
    Print p = new Print(imprimir);
    p.PrintAndCut();//this one does the dirty job for meAfter this Ive tried calling System.ou.flush() with no help.
Here is the code of the class:
public class Print  implements Printable {
   static JTextArea textarea = new JTextArea();
   static JFrame   window = new JFrame("Print Sample");
    public Print(String imprimir) {
        Font titleFont = new Font("helvetica", Font.BOLD, 12);
        textarea.setFont(titleFont);
        textarea.append(imprimir);
  public static void main(String args[])   {
    final Container cp = window.getContentPane();
    LayoutManager lm = new FlowLayout(FlowLayout.CENTER, 20,20);
    textarea.setEditable(false);
    window.setVisible(false);
  //this is the function I use to print anything I want on the POS printer
   public void PrintAndCut() throws Throwable {
      PrinterJob printerjob = PrinterJob.getPrinterJob();            // get a printer job object
      PageFormat format = new PageFormat();//job.defaultPage();
      format.setOrientation(PageFormat.PORTRAIT);
      printerjob.setPrintable(this, format);     
      try {
         printerjob.print();            // print the page(s)  (this method with call the page painters)
        } catch (PrinterException exception) {
         System.err.println("Printing error: " + exception);
   public int print(Graphics graphics, PageFormat pageFormat, int pageIndex)
      throws PrinterException {
       String strText =null;    // text string to output
       int lineStart;           // start index of line in textarea
       int lineEnd;             // end index of line in textarea
       int lineNumber;          // current line in textarea
       int lineCount;           // total number of lines in textarea
        if (pageIndex >= 1 )
           return Printable.NO_SUCH_PAGE;
       // move the drawing origin to the imageable area ( makes sure its drawn where the printer can )
       graphics.translate((int)(pageFormat.getImageableX()), (int)(pageFormat.getImageableY()));
       graphics.setColor(Color.black);
       // get the text from the textarea one line at a time
       lineNumber = 0;
       lineCount = textarea.getLineCount();
       strText = textarea.getText();
       while (lineNumber < lineCount) {
          try {
             lineStart = textarea.getLineStartOffset(lineNumber);
             lineEnd = textarea.getLineEndOffset(lineNumber);
             strText = textarea.getText(lineStart, lineEnd-lineStart);
          } catch( Exception exception) {
             System.out.println("Printing error:" + exception);                  // have to catch BadLocationException
          // determine drawing location of each successive line
          graphics.drawString(strText,0,(lineNumber + 1) *20);
          lineNumber = lineNumber + 1;
        return Printable.PAGE_EXISTS;                      // page was drawn successfully (return NO_SUCH_PAGE if not)
   }Any help or advice would be appreciated. Thanx
