QuickDraw GX 1.1.5: No LaserWriter 12/640 Support

I am unable to use some of the unique LaserWriter 12/640 features using QuickDraw GX 1.1.5.
Quick Draw GX 1.1.5 was not tested with nor provides support for printers Apple introduced after the LaserWriter 16/600. Therefore, many of the LaserWriter 12/640's specific printing features are not supported. There are no plans at this time to provide support for the LaserWriter 12/640.
