Toner-based marking technologies in production printing apply in 3 areas: transactional printing, commercial printing and industrial printing. Each area is imposing specific requirements as well on the marking engine as on the toner and on the front-end. One of the main advantages of toner-based printers consists of its intrinsic “offset” character, meaning that at least one intermediate member is physically separating the inking or development process from the transfer/fixing of the image on the final carrier. This opens the printing process for a much wider choice of printing media and improves the up-time and the performance. The never-ending question whether the future is dry or liquid, will remain unsolved as there are advantages for both.
