I forgot to mention that HP also have a "composite" B&W mode, which 
introduces a little colour into blacks+gray/s printing. It gives better 
Dmax and tonal smoothness with wider paper compatibility (reduced 
bronzing) than blacks & grays alone. Tint is uncontrollable since there is 
no ABW functionality. It is quite metameric, and in my limited experience 
prints are not so much cool but a lurid cyan. Which is why it is so 
forgettable.
