Abstract
A printing drum (10) contains printing elements (30). These printing elements (30) are each designed as a depression in the surface of the printing drum (10). The printing elements (30) are arranged in the manner of matrix rows. A printing drum (10) has more than one matrix row (33) of printing elements (30). Each printing element (30) contains a selectively activatable heating device (31) which is capable of heating ink (13) contained in the printing element (30), in such a way that, utilizing a gas bubble formed at the same time, the ink is ejected out of the printing element (30) in the direction of a recording medium (14). The printing elements (30) are filled with ink (13) in an inking station (11).
