ABSTRACT:
The printer with a substrate support (1) is furnished with a layer structure in a print support cross-section (11). The layer structure comprises a metallic print bar (13), a vibration-attenuating damping layer (14), and a metallic intermediate layer (15) disposed sequentially in print element operation direction (12), where the intermediate layer (15) acts only functionally as "intermediate layer." In order to avoid a space-requiring and bulky layer structure of an insulating layer (16), neutralizing the frequencies of contacting components, the frequency-neutralizing insulating layer (16) is formed by elastic caps (18) at the ends (17a, 17b) of a unit, where the unit is formed by print bar (13), damping and absorbing layer (14), and intermediate layer (15). The elastic caps (18) can be slid into the recesses (19) of the printer side walls (20).
