In a thermal printer in which ink is transferred from a single-use thermal print ribbon to a substrate such as packaging material by energising selected print elements of a thermal print head (22), a first print run is executed by energising only a group of print elements in registry with one half of the ribbon width so that ink is depleted only from one half of the ribbon, and a second print run is executed by energising the same group of elements using the same ribbon but with the ribbon supply and take-up spools interchanged in order that ink is depleted only from the other half of the ribbon. This allows printing on comparatively narrow printing areas using ribbon which is at least twice the width of the printed area without undue ribbon wastage and with reduced ribbon breakage frequency compared to the breakage frequency with a ribbon of a width nearer to the width of the printed area.

Dans une imprimante thermique où l'encre est transférée d'un ruban d'impression à utilisation unique à un substrat tel qu'un matériau d'emballage par l'excitation d'éléments d'impression sélectionnés faisant partie d'une tête d'impression thermique (22), un premier passage est exécuté par l'excitation d'un groupe d'éléments d'impression en utilisant une moitié de la largeur du ruban de sorte que l'encre d'une moitié du ruban seulement est utilisée, et un second passage est exécuté en excitant le même groupe d'éléments, mais en interchangeant les bobines débitrice et réceptrice du ruban pour que seule l'encre de l'autre moitié du ruban soit utilisée. Ceci permet de réaliser des impressions sur des zones relativement étroites en utilisant un ruban dont la largeur est au moins le double de celle de la zone imprimée sans gaspiller le ruban et en réduisant la fréquence de rupture du ruban comparativement à la fréquence de rupture des rubans dont la largeur est comparable à celle de la zone imprimée.
