Java (native) print dialog - change icon

I use PrinterJob.printDialog() to let the user select a printer and change various print settings.

However the dialog is always displayed using the standard Java coffeecup icon and not the one from my main window (JFrame).

How can I change the icon for that dialog?

I'm using the following piece of code:

PrinterJob pj = PrinterJob.getPrinterJob(); 
pj.printDialog(); // how do I change the icon for the dialog that is displayed here

... // process the selection from the dialog

Normally a JDialog inherits the icon from the "parent" JFrame, but in this case I cannot pass or specify a parent window for that dialog

I'm using Java6
