Printing strings

Question

Hello,
I have a problem printing in java.
Printing simple text trough g.drawString("printing text", x,x); goes fine,
but whenever I try to get text from a TextField printed I get the nullpointer.
When I press the print button the strings do have value, but I suspect I need to get the text out of the textfields somewhere different in my application.
This is what I've got so far, note: printing the typed strings works well, but when printing from my java strings
it won't work. I have also documented these things in the code below.
    public int print(Graphics g, PageFormat pf, int page) throws PrinterException
          strFirstname = txtFirstname.getText();  // Where I get the value from the textfields
          strLastname = txtLastname.getText();
      if (page > 0)
      {           // We have only one page, and 'page' is zero-based
           return NO_SUCH_PAGE;
          Graphics2D g2d = (Graphics2D)g;
          g2d.translate(pf.getImageableX(), pf.getImageableY());
          g.drawString ("First name:", 0, 75); //These lines get printed perfectly.
          g.drawString (strFirstname, 115, 75);
          g.drawString ("Last name:", 0, 100); //This line is getting printed perfectly aswell.
          g.drawString (strLastname, 115, 100);
          return PAGE_EXISTS;
}And the code from the print button:
    private class PrintHandler implements ActionListener
         public void actionPerformed (ActionEvent e)
         PrinterJob job = PrinterJob.getPrinterJob();
             Book book = new Book();
         PageFormat documentPageFormat = new PageFormat();
         documentPageFormat.setOrientation(PageFormat.LANDSCAPE );
         book.append(new frmModify(), documentPageFormat); // frmModify = the class wich extends the frame and implements PrintAble.
         job.setPageable(book);
         System.out.println(strFirstname); // The values of the strings get printed perfectly IN THE CONSOLE, not on paper.
         System.out.println(strLastname);
         boolean ok = job.printDialog();
         if (ok)
             try
                  job.print();
             } catch (PrinterException ex)
              /* The job did not successfully complete */
                  ex.printStackTrace();
    }

I might have come closes to the answer but I'm not there yet !
When I use this piece of code in my constructor (where the textfield is made)
txtFirstname.setText ("Derek");
txtLastname.setText ("Jeter");The string in the print method ain't null anymore but it prints correctly "Derek" and "Jeter" in the console.
So it might has something to do with the print method being called before the textfields are actually called by my stored procedure.
This is how I call the frame:
                fmod = new frmModify();
                fmod.vernieuwOfficeCC(); // Renewing my choice menu's.
                fmod.vernieuwBusinessUnitCC(); // Renewing my choice menu's
                fmod.showUser(oFirstname, oLastname, oJobtitle, oDepartment, oPersref, oOffice, oBusinessUnit); //This is where they fill the text fields with data.
                fmod.openWindow(); //Method with setVisible(true);Actually it has to be in the way I call the frame and methods. I just can't figure it out at the moment.
Because when the constructor frmModify() is called the text fields are empty because they won't get filled until showUser();.
Any idea how I fix this ?
