In interactive printing, which is printing character by character through key activation, link-up is obtained between character boxes so that characters such as underscoring or accounting underscoring, for example, can be continuous from character box to character box when printing with a resistive ribbon from a thermal print head. To obtain continuous underscoring in interactive printing, the currents to the electrodes of the thermal print head stay on for two additional pels (printing elements) past the end of the character box. With a character box having a width of 36 pels for a 10 pitch character, the continuous conducting of the electrode currents for the two additional pels beyond the boundary of the character box enables overlapping between the two character boxes.
