        Description copied from interface: Print
        Returns a PrintIterator for laying out the contents of this Print. The iterator uses a snapshot of the print at the time this method is invoked, so subsequent changes to the Print will not affect the output of the iterator.
        Specified by:
        iterator in interface Print
        Parameters:
        device - the graphics device this Print will be drawn onto.
        gc - the graphics context to be used for calculating layout and drawing the Print's contents.
        Returns:
        a PrintIterator for laying out the contents of this Print.
