Abstract
A thermal head driver system cyclically and independently drives at least two thermal heads having each a plurality of electric resistance elements. A storage system cyclically stores an image information data, the image information data cyclically being each of at least two types of image information data, respectively corresponding to the thermal heads. A selector system cyclically and correspondingly selects which thermal head should be driven in accordance with the cyclical storage of the types of image information data in the storage system, such that the electric resistance elements of the thermal head, selected by the selector system, are selectively and electrically energized in accordance with a corresponding type of image information data cyclically stored in the storage system.
