The Development Of Control System Of Large Character Ink Jet Printer

In recent years, with the code-spurted technology applicable in food service industry, More and more frequently people contact to the ink jet printer, domestic demand to ink jet printer increased rapidly. However ink jet printer market in China, the foreign brand occupied the market share already surpass 80%, the domestic brand only had about 20%. Large character inkjet printer is basically dominated by foreign brands. Domestic only advantage of cheap inkjet printer, and these domestic enterprises mostly continuous inkjet printer. It is urgent for more domestic manufacturers to develop and produce independent intellectual property rights of the ink jet printer. This will not only meet the needs of domestic enterprises to significantly reduce the use of full-life inkjet printer costs, save a lot of foreign exchange, but also conducive to research and development in the Coding technical reserves, the world's advanced printing technology to shorten the gap between.It is in this paper as a background, develop the control system of large character ink jet printer . In this paper, first introduced the core technology of large character ink jet printer print the way DOD works and its benefits relative CIJ printing methods. On this basis, set out the overall framework of the system design, from hardware, respectively ink jet printer host and user terminals in various parts of key modules to achieve a detailed description of the circuit at the same time focuses the inkjet printer host and user terminals and pairs of computer communication protocols and Coding software design and implementation. In addition, focusing on the electromagnetic switch control inkjet supply module implementation principle and theoretical analysis, and has successfully designed and manufactured in kind of the module. Lastly, a detailed description of the inkjet printer control system hardware, PCB production and inkjet printer control system of the physical parts of the circuit debugging steps described in the debugging process encountered problems and solutions to these problems. This paper developed a large character inkjet printer control system, you can print 52 ASCII, the storage function with 128 memories, set in the Coding that has set the point size of the print, print delay time, print direction, light sensor status , font width and other features, also has a clock, calendar and count functions. User interface in Chinese liquid crystal display, user friendly interface, users can easily master the methods of operation, to meet user needs. Inkjet supplies electrical power using self-developed parts of the electromagnetic switch control module, longer service life and reduce material cost, to achieve high-quality, low-cost printing purposes.
