Toute diminution de la qualité d'impression est réduite à un minimum en augmentant efficacement la force de transport du papier. L'imprimante de type à transfert thermique d'après la présente invention comprend : une unité d'entraînement de rouleau de platine (105) qui transporte un papier d'enregistrement (3a) et un ruban d'encre (12) en entraînant en rotation un rouleau de platine (5) pendant une impression ; un rouleau de saisie (6) qui, en association avec un premier rouleau pinceur (7), intercale le papier d'enregistrement dans une section située entre un rouleau de papier (3) et le rouleau de platine ; et une unité d'entraînement de rouleau de saisie (106) qui transporte le papier d'enregistrement en entraînant en rotation le rouleau de saisie.
