Abstract

An electronic printing device, comprising the combination of: a plurality of thermally separate elements, each including resistance heating means; means for perceiving the temperature of each of the elements individually; and means for selectively applying energy to the resistance heating means of the elements, at a voltage level related to the temperature of said element.
