Printing Resolution

How do I take advantage of the full resolution of the printer? When I do a default print using the printer service I seem to get the resolution of the window that I am printing, is there some way of getting the resolution of the printer not that of the display device? I have a Java2D graphics window, and have tried the following with no success:
Graphics2D graphics2D = (Graphics2D) graphics;
// Scale the printout to fit the pages.
double scalex = format.getImageableWidth() / getWidth();
double scaley = format.getImageableHeight() / getHeight();
double scale = Math.min(scalex, scaley);
// translate to the printable (0,0) location on the paper.
graphics2D.translate((int) format.getImageableX(),
(int) format.getImageableY());
graphics2D.scale(scale, scale);
// then paint the graphics 2D object.
I still get jagged lines on the printer device. The original window maybe displayed at 600x600.

I suspect you are printing a double-buffered swing component window
using paint().
That paints to the swing back buffer which is unsurprisingly at screen
resolution
and then that is what you are sending to the printer.
Use Component.printAll() to print a Component, *not* Component.paint().
