With the changes of the times, a lot of high-tech has entered our lives. These high-tech can not only help us to complete, we can't finish it, but it is also convenient to use, which saves us a lot of trouble. Such as dot matrix printers, its application is very extensive, as used for more than banking, telecommunications and other financial sector counter business use, handling more general offices and financial institutions, and so on. The following small series will take you to see how the dot matrix printer works.
The printer itself is a microcomputer system, and the whole machine is controlled by the CPU. Its control program exists in the ROM, so that the CPU can be turned on to work. The CPU can receive various control commands of the panel, and can also receive instructions from the host and interpret and execute various instructions. These connections are made through the interface of the computer.
The working principle of the stylus printer: The stylus printer uses the principle of mechanical and circuit drive to make the printing pin impact the ribbon and the printing medium, and then print out the dot matrix, and then the dot matrix constitutes characters or graphics to complete the printing task. In the online state, the print control command, the character print or the graphic print command sent by the PC is received through the interface, and after processing by the CPU of the printer, the image code corresponding to the character or the graphic is searched from the font library, such as one column and one column. Find the code and send it to the print head drive circuit to energize the print head out of the printer.
The basic printing procedure of the dot matrix printer is: start the word car → check whether the print head enters the print area → perform print initialization → drive the print head to print a column according to the character or graphic code → generate column spacing → generate word spacing → one line prints, start and lose The paper motor drives the print roller and the paper feed line one line → line feed.
After reading the above introduction, I believe you should have some understanding of the working principle of the dot matrix printer! If you have any questions about the dot matrix printer, you can go to the relevant website to check.
