I found this description of durabright ink.  It seems to be a variant 
of pigment based inks.

The question is if the print head is really any differet for pigment 
based inks.  The cleaning system and regiment is probably different. 
But the head could be identical.

When someone takes one apart, take a picture of the holes in the head 
or put it under a microscope next to a penny... Then we can see the 
hole size relative to Lincoln's nostrils.
