Prints the page at the specified index into the specified Graphics context in the specified format. A PrinterJob calls the
Printable interface to request that a page be
rendered into the context specified by
graphics.  The format of the page to be drawn is
specified by pageFormat.  The zero based index
of the requested page is specified by pageIndex.
If the requested page does not exist then this method returns
NO_SUCH_PAGE; otherwise PAGE_EXISTS is returned.
The Graphics class or subclass implements the PrinterGraphics interface to provide additional information. If the Printable object aborts the print job then it throws a PrinterException. 
Params:
graphics – the context into which the page is drawn
pageFormat – the size and orientation of the page being drawn
pageIndex – the zero based index of the page to be drawn
Throws:
PrinterException – 
        thrown when the print job is terminated.
Returns:
PAGE_EXISTS if the page is rendered successfully
        or NO_SUCH_PAGE if pageIndex specifies a
        non-existent page./**
