Domino's DD3 dot matrix laser printer

Domino's DD3 dot matrix laser printers use the patented RainbowTM 7 laser tube technology for inkjet printing. Most of the traditional laser machines use one laser tube, which consumes a lot of energy, and the frequency of failures also increases. The new laser can print at a voltage of 110 to 150 volts without any increase in body temperature. The 7 laser tubes of the DD3 each occupies 1/7 of the line load. At the same time, accurate optical printing is achieved using simple optical principles, which improves printing performance. When one or two of the seven laser tubes have problems, production can proceed as usual by simply swapping a good laser tube into the middle five positions and simply making a few clicks on the keyboard or data line. The print format is converted to a 5x5 dot matrix so that there will be no missed hits. The unique anti-counterfeiting coding technology of this model is currently applied on the “Hongtashan” cigarette case, which plays a very good anti-counterfeit effect.
