Classification of eco-solvent printer
1, according to principles of classification In accordance with the principle of the printer, the printer into impact and nonimpact type. Series of dot matrix characters Fu Fei main impact printer are inkjet and thermal printers in two ways. ① ink-jet printers. The most widely used printer. The basic principle is to live after the jet deflection fog after electrode directly on the paper form the desired font style. Its advantages are composed of characters and images of Indian point are much smaller than pin dot-matrix printers, thus characters of high resolution, high printing quality and clarity. Given the flexibility to easily change the size and font of characters. Printing with plain paper, can also use the typewriter printed directly on the products. In the formation of character and graphics without mechanical wear, printing and low energy consumption. Print speeds of up to 500 characters per second. Widely used a charge control (high pressure) and random ink-jet type (negative pressure) ink-jet technology, in recent years there have been dry ink-jet printing technology.
II thermal printer. Through the print head resistance of pulse current produces heat to heat-sensitive paper, its heat discoloration, thus printed characters and images. Main characteristic is noise-free, the structure is light and small, print clearly. Weakness is slower, and save the poor handwriting. Line dot matrix character Fu Fei impact printers include laser, electrostatic, magnetic and light emitting diode printer. ① laser printers. Laser source issued of laser beam through character lattice information control of sound light deflection device modulation Hou, into optical system, through more surface Prism on rotating of photographic drum for horizontal scan, so in photographic drum Shang of photoconductive film layer Shang formed character or image of electrostatic dive like, again after developer, and turned printing and fixing, will in paper Shang get by needed of character or image. Main advantage is the high print speeds, up to more than 20000 lines/min. Printing of high quality, low noise, use plain paper, printable characters, graphics, and images. Because of high print speed, macro point of view, just like print one page at a time, it is also known as page printers. ② electrostatic printer. Pulse voltage directly on special paper with a layer of dielectric material, to get on the dielectric electrostatic latent image, by developing, heat fixing forms characters and images. It is characterized by high quality of printing, writing does not fade, long-term preservation, generated image of small power consumption, noise-free, simple and reliable. Requires the use of special paper and the cost is high. ③ magnetic printer. It is the application and development of electronic technology. With magnetic media formed Word Fu Qian, you do not need high power laser source, the advantage is less sensitive to changes in humidity and temperature. Printing speeds up to 8000 lines/min. Simple structure, low cost. Black-light emitting diode printer. Apart from using light emitting diode as light source, and it works like a laser printer. By using light-emitting diodes, lowers costs, reduces the power consumption.
2, classified according to work Divided into dot-matrix printers, dot matrix printers, inkjet printers, laser printers, and so on. Physical contact of dot matrix printers by printer and paper to print your image, and two by spraying a toner to print the image. 3, classified by use Office and generic printer In this application, the dot matrix printer has been occupying the leading position. Because of dot matrix printers with medium resolution and print speed and cheaper supplies, but also has a high speed skip, multiple copies printing, wide-format printing, easy repair, is still in Office and transaction printing reports, invoices and other optimization models. Commercial printers Commercial printer refers to a commercial printer for printing because printing high quality requirements in this area, sometimes working with pictures and documents, therefore, generally using high-resolution laser printers. Special printers Specific printer generally refers to a variety of micro printer, passbook printer, push the receipt printer, barcode printer, thermal printer, such as printer for dedicated systems.
Home printer Home printer refers to a home computer accessory into the family of printers, according to the characteristics of the family using the printer, color ink-jet printer has become the mainstream of the current low-grade products. Portable printers Portable printers are generally used for matching with the laptop, with small size, light weight, battery-driven, easy to carry and so on. Network printer Network printers for network systems, to provide printing services for most people, so this printer has a print speed, automatically switches the simulation models and network protocols, and easier for your network administrator to management, etc.
