Abstract

A device that prints with ink includes an ink reservoir for ink and an arrangement of multiple printing elements, for instance printing heads. The printing elements are identical with one another, they generate ink drops, and they are supplied in parallel with ink from a joint supply line. A further element, which is different from the printing element and which is controllable in terms of its ink flow, for instance a pump, is supplied with ink in parallel with the printing elements by the same supply line. Undesirable hydrostatic pressure changes in the ink are reduced as much as possible, or even eliminated.
