5 droplet sizes, 6 inks... That's 36 bits unless there is some magic behind
it.

 Hell, I can't think of any commonly used technique other than dye
sublimation that you are likely to find this for.  There is a reason that
printer output looks the way it does under magnification.  There is also a
reason why the dpi given for color capability for the multifunction unit
you selected is so much higher for color than black and white.
