Fit panel on paper

So I have 2 panel in 1 panel. On 1 panel is chart, and on second is some information. I want to print that panel witch contains that two panel. So I used some tricks for panel to fit to paper, but it didn't work fully. Here is my printing job:

public void printComponenet(Component comp){

      PrinterJob pj = PrinterJob.getPrinterJob();
      pj.setJobName(" Print Component ");
      PageFormat pf = pj.defaultPage();
      pf.setOrientation(PageFormat.LANDSCAPE);

      pj.setPrintable (new Printable() {    
            public int print(Graphics g, PageFormat pf, int pageNum){

                if(pageNum > 0) 
                {
                    return Printable.NO_SUCH_PAGE;
                }

                Dimension compSize = comp.getPreferredSize();
                comp.setSize(compSize);

                Dimension printSize = new Dimension();
                printSize.setSize(pf.getImageableWidth(), pf.getImageableHeight());

                double scaleFactor = getScaleFactorToFit(compSize, printSize);

                if(scaleFactor > 1d) 
                {
                    scaleFactor = 1d;
                }

                double scaleWidth = compSize.width * scaleFactor;
                double scaleHeight = compSize.height * scaleFactor;

                Graphics2D g2 = (Graphics2D) g.create();

                double x = ((pf.getImageableWidth() - scaleWidth) / 2d) + pf.getImageableX();
                double y = ((pf.getImageableHeight() - scaleHeight) / 2d) + pf.getImageableY();

                AffineTransform at = new AffineTransform();
                at.translate(x, y);
                at.scale(scaleFactor, scaleFactor);
                g2.transform(at);
                comp.printAll(g2);
                g2.dispose();

                comp.revalidate();
                return Printable.PAGE_EXISTS;
            }
      }, pf);
      if (pj.printDialog() == false)
      return;

      try {
            pj.print();
      } catch (PrinterException ex) {
            // handle exception
      }
}

And when I print that panel, it looks like this.Here

How should I fix it? Bottom side of paper is okay, I just didn't screenshoted it fully.

Instead of scaling the rendered graphics, which will only worsen resampling artifact, override the getPreferredSize() method of the enclosing Component and specify the desired size. Use a layout such as FlowLayout to preclude resizing. As it appears that you are using JFreeChart, related examples may be found here and here.
