Abstract: A control arrangement for a belt printer having characters arranged in successive series on an endless belt and passed continuously in front of a print support and hammers adapted to be actuated by a control device. A recording store is connected to a calculating unit and records information relating to each character to be printed along a line on the print support. A scan register contains information relating to the coincidences between the characters and the striking members at any given time. Information corresponding to the condition when a predetermined character is to be struck by a given hammer in the course of a given scan, is stored in a storage member along with information indicative of whether or not the predetermined character is repeated in the series of characters.
