I'm trying to print out some simple RTF-formatted text to a laser printer using a JTextPane.

The result looks fine on a software PDF printer (FreePDF XP), but the text doesn't have proper space between it's formatted parts when print to a real printer.

Edit: I have uploaded an example output (The bottom is the scanned printout)

Example

It seems to me that there is a problem with the Graphics object starting to paint the indiviual parts of the RTF code. As if it couldn't figure out where to correctly put each part (the X coordinate).

Do I have to provide some kind of coordinate system translation?

The simple test code used:

import java.awt.BorderLayout;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.print.PageFormat;
import java.awt.print.Printable;
import java.awt.print.PrinterException;
import java.awt.print.PrinterJob;
import javax.swing.JFrame;
import javax.swing.JTextPane;

class MyTextComp extends JTextPane implements Printable
{
  public MyTextComp()
  {
    setContentType("text/rtf");
    setText("{\\rtf1 HelloWorld! \\par {\\i This} is formatted {\\b Text}.}");
  }

  public void paintComponent(Graphics g)
  {
    super.paintComponent(g);
  }

  public int print(Graphics g, PageFormat pf, int pIndex)
  {
    if(pIndex > 0)
      return Printable.NO_SUCH_PAGE;

    Graphics2D g2d = (Graphics2D)g;
    g2d.translate(pf.getImageableX(), pf.getImageableY());

    /* Now print the window and its visible contents */
    printAll(g);
    return Printable.PAGE_EXISTS;
  }
}

public class TextCompPrint extends JFrame
{ 
  public static void main(String[] args) throws PrinterException
  {
    TextCompPrint myFrame = new TextCompPrint();
    MyTextComp    myComp  = new MyTextComp();

    myFrame.add(myComp, BorderLayout.CENTER);
    myFrame.setSize(200, 200);
    myFrame.setVisible(true);

    PrinterJob pj = PrinterJob.getPrinterJob(); 
    pj.setPrintable(myComp);
    pj.print();
  }
}
