Important to remember, though, that changes to PostScript from Adobe are merely
enhancements for speed improvement and device specific things such as
halftoning accuracy/speed. Any increment to the PostScript version will never
make the RED book obsolete, nor any printer adhering to at least version 23.0
obsolete (the version of the RED book). The RED book commands will always be
supported. It is the underlying standard. Any enhancements above that are
merely extensions.
