Abstract
Streams of ink droplets are formed of a material which changes from transparent or colorless to a color when subjected to a selected energy source. A print pattern is produced on a movable paper through selectively controlling the droplets to which the selected energy source is applied. The droplets which remain transparent or colorless because of not being exposed to the selected energy source can be deactivated by a second source of energy so that these droplets will not subsequently print.
