You need to get a separate Graphics object using the PrintJob 
getGraphics() method for each page you want to print.

If you have a large canvas and you want to subdivide it into 
pages.  I believe you would use the Graphics translate() method 
to adjust the origin of the Graphics context, and the clipRect() 
method to clip the printing area.

I have done similar things, but not this exactly, so I am not 
positive that this will work, but I believe it is the right 
approach.  I may have the signs mixed up.

/**
**  Print part of a component.
*/
public void printPage( PrintJob job, Component c, Rectangle r ) {
    Graphics g = job.getGraphics();
    g.translate( -r.x, -r.y );
    g.clipRect( 0, 0, r.width, r.height );
    c.paint( g );
    g.dispose();
}
