[ExI] TECH ANSWER

Neither. It prints ink with specific light-absorption and reflection
qualities. The color is generated in the visual cortex and is partially the
function of the type and intensity of ambient light and surrounding objects.

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.
