Unless it's electronic ink, which prints pixels that can later be black or white.

Or it is a 3D printer with no paper substrate, in which case the white must be in what it prints.

 

 

Ja.  It also depends on how you define white.  Some substances are reflective in some frequency bands and absorptive in others.  So ink can be simultaneously white and black, depending on you how you look at it.
