Abstract (en)
[origin: EP0043434A1] Described, is a printing mechanism allowing full exploitation of the potential of dot matrix printing. Dot forming elements (7, 8) are mounted on a carrier (5) for transport past an array of hammers (6) located in front of media (4) to be marked upon. The dots or carrier are impacted by the hammers to form dots on the medium. By appropriate control of motion of the printing medium and timing of the hammer impacts, a dot may be formed anywhere on the surface of the medium. This allows unlimited character font set generation as well as psecial character printing. In addition, the mechanism permits an all points available graphics generation system and full control for variable vertical spacing of printed elements and of variable horizontal spacing of the printed elements. To improve the throughput speed, a revesible motor is used for driving the dot element carrier and a plurality of dot font sizes and shapes are provided on the carrier. By selection of the required font size and shape and by comparison with the presently known position of the carrier, the quickest access to the next desired dot font for any given hammer can be achieved.
