Page size when printing html from JTextPane

I have a JTextPane that reads a .htm file and displays it. If I change the font size it changes the appearance on the JTextPane but when I try to print the data looks the same. I have a large html table and I can only get 20 columns on one page. I would like to shrink the table down so I can get more on a page. Here is the code I am using to print the JTextPane:
private void startPrint() {
try{
PrinterJob prnJob = PrinterJob.getPrinterJob();
prnJob.setPrintable(this);
if(!prnJob.printDialog())
return;
prnJob.print();
}
catch (PrinterException e) {
e.printStackTrace();
System.err.println("Printing error: "+e.toString());
}
}
public int print(Graphics pg, PageFormat pageFormat,
int pageIndex) throws PrinterException {
Dimension d = prtPane.getSize();
double panelWidth = d.width;
double panelHeight = d.height;
double pageHeight = pageFormat.getImageableHeight();
double pageWidth = pageFormat.getImageableWidth();
double scale = pageWidth/panelWidth;
int totalNumPages = (int)Math.ceil(scale * panelHeight / pageHeight);
if(pageIndex >= totalNumPages)
return Printable.NO_SUCH_PAGE;
Graphics2D g2 = (Graphics2D)pg;
g2.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
g2.translate(0f, -pageIndex * pageHeight);
g2.scale(scale, scale);
prtPane.print(g2);
return Printable.PAGE_EXISTS;
Does anyone have any ideas on how to fix this?
Thanks

Hi Chris,
I want a solution from you.
Are you using textpane.setEditorKit(new HTMLEditorKit()) and
setting the doc to the textpane?? If so how to make the portion of the text in the textpane to be (bold,italic,unedrline,foreground) by selecting and clicking buttons on the toolbar on the top??

No I don't use the HTMLEditorKit. I just create the html in a file and then use .setPage( to insert the HTML into the JTextPane. I still haven't figured my problem out. I can change the font size and it affects how it looks on the JTextPane but when I print it always comes out the same size. Does anyone have any ideas?
