La circonférence de chaque cylindre est de préférence déterminée par la valeur de pas de base multipliée par un nombre premier. Dans un mode de réalisation de l'invention lesdits cylindres (9, 5, 7) d'impression de tables comprennent une paire de cylindres (9, 5, 7) d'impression de tables ayant des circonférences différentes, chacun des cylindres de la paire de cylindres (9, 5, 7) d'impression de tables étant agencé pour imprimer une pluralité de rangées de nombres, les nombres contenus dans chaque rangée étant espacés de ceux de la paire de cylindres d'impression de tables.
