Abstract (en)
A dot matrix printer (10) comprises a printing unit (14) including a print head (16) and an elongated counter-pressure element (20) between which a printing material can be guided along a transport plane, and at least one biasing element (18) on which the counter-pressure element (20) is mounted and biased against the print head (16). Both end regions (38, 40) of the elongated counter-pressure element (20) are each coupled via a conversion mechanism (34, 36) to a stationary, torsion-proof compensating bar (32) that is rotatably mounted about its longitudinal axis. A displacing movement of one of the two end regions (38, 40) of the counter-pressure element (20) directed transversely to the transport plane is converted via the associated conversion mechanism (34, 36) into a rotary motion of the compensating bar (32). This rotary motion of the compensating bar (32) is converted via the respective other conversion mechanism (36, 34) into a compensation movement of the other end region (40, 38) of the counter-pressure element (20), which compensation movement has the same direction as the mentioned displacing movement.
