Abstract

Une imprimante thermique comprend une tête d'impression (18) possédant une pluralité de groupes de pixels thermiques (50). Les pixels thermiques (50) dans chaque groupe sont adressés simultanément en parallèle. Chaque groupe est adressé une pluralité de fois. Le dispositif comprend un circuit (42) mettant sélectivement sous tension les pixels thermiques (50) de chaque groupe lorsqu'ils sont adressés, jusqu'à ce que chaque pixel thermique atteigne à une température où il peut communiquer de l'énergie à un organe de support et applique une certaine quantité de colorant sur un récepteur correspondant à une densité désirée de colorant dans un pixel d'image.
