Application and Basic principle in Thermal Printer
by Keberultrasonic Li keberultrasonicThermal printing technology is earliest applied in fax device. Its standard principle should be to transport information printer receives into heating of dot matrix solitary control thermal unit and develop image by heating thermal coat on thermal paper. At current, Thermal printer mechanism suppliers is extensively utilized in fields like POS end technique, bank system and medical instrument. Thermal printer can only use special thermal paper. On thermal paper, there's a coat that will bring forth chemical response and additional discolor as soon as being heated, being similar with sensitive movie. But, this coat would discolor once encountering heat. Taking utilization of such characteristic of thermal printer system, there emerged thermal printing technologies.
According to thermal component arrangement approach, thermal printer is typically divided by thermal printer system producers into thermal line dot program and thermal serial dot method. Serial dot thermal belongs to solution of early time period which can be mostly utilized in event that does not have high demand on printing speed. Line dot thermal emerged in 90s, 21st century. Its printing speed is much quicker than that of serial dot thermal. At existing, the quickest pace has reached 220mm for every 2nd. As a way to realize high velocity thermal printing, except for selecting high pace thermal printing head, corresponding control panel should really properly match it.
Pos printer supplies operating principle typically performs as following. On its printing head, there is certainly installed semi-conductor heating component. There is also thermal printer system with autocutter. When printing head heats and contacts thermal printing paper, required picture would be printed. The theory is related to that of thermal fax equipment. Picture generates just after heating and chemical reaction inside the embrace, which works in certain temperature. High temperature would accelerate chemical response. When temperature is reduce than 60, paper can modify into dim only after speedy a lengthy time even several years. Even though, when temperature reaches 200, such response would complete inside a number of microseconds.
Thermal printer heats in ascertained position selectively and thus generates corresponding picture. Heating is supplied by a little electrical heater on printing head contacting thermal materials. Regardless of whether heater is arranged into sq. or bar sample is controlled by printer logics. When it is driven, there would create corresponding picture with heating elements. The logical circuit controlling heating elements controls paper feeding at the very same time. As a result, there prints out picture on complete label or paper. This technology has been already applied by thermal printer system suppliers in paper printer and label printer.
With regard to needle printer, thermal printing is of rapid pace, reduced seem, crystal clear printing and handy application. Nevertheless, thermal printer can't Portable printer china and receipt printed can't be completely preserved. Inside the situation most effective thermal paper is utilized, it can preserve for 10 years. On the opposite, needle printer can do with double layers paper. If fantastic colored tape is utilised, printing receipt can preserve for a extended time. But needle printer is of slow pace, massive sound, coarse printing mark and needs normal substitute of coloured tape. When users need printing receipt, it is recommended to use needle printer. Thermal printer is superior applied inside the situation of printing other sort receipt.
