Driver selon la revendication 1, dans lequel lesdits moyens de production de la tension de balayage (10,40) comprennent un circuit de constante de temps constitué d'une résistance et d'un condensateur, un moyen de commutation destiné à actionner ledit circuit de constante de temps pour fonctionner selon un cycle prédéterminé et un amplificateur destiné à délivrer la variation de tension provoquée dans ledit circuit de constante de temps sous forme d'un signal de sortie à basse impédance.
  4. Driver selon la revendication 1, 2 ou 3, dont les moyens de déclenchement (12) et les moyens de production de signaux de commande (15) sont montés sur un chariot d'une imprimante série à jet d'encre dans laquelle ledit chariot déplace une tête d'imprimante constituée par lesdites buses (1a) et lesdits éléments d'électrostriction (4,13).
  5. Driver selon la revendication 1, dans lequel    les moyens de production de la tension de balayage (10,40) comprennent un circuit de constante de temps connecté en série à une source électrique par l'intermédiaire d'au moins un moyen de commutation et un moyen amplificateur comprenant une paire de transistors dont l'un au moins est commandé sur la base d'un potentiel électrique dudit circuit de constante de temps et connecté en série à ladite source électrique ;    les moyens de déclenchement (12) appliquent la tension de balayage desdits moyens de production de tension de balayage (10,40) aux éléments correspondants desdits éléments d'électrostriction (4,13) selon un rythme prédéterminé ;    et ledit driver comprenant de plus    un moyen de commande de tension de balayage pour commander lesdits moyensde production de tension de balayage (10,40) en synchronisme avec le moyen de production du signal de commande (15).
  6. Driver selon la revendication 5, comprenant en outre un moyen de changement de constante de temps destiné à changer la constante de temps dudit circuit de constante de temps.
