The quantity of color ink used in the latest "two gray" printer's drivers is 
minimal, and the pigment inks involved are very stable. So both illuminant 
metamerism and color shift over time are also very minimal. And the issue of 
"color casts" is the strength as well as the weakness of these systems: you can 
potentially control that subtle color, and make it do what you want.
