When the printer controller receives data from the computer, the printer is generally taken to work in two ways: one is the data to print directly to the interpreter, known as "section work", the printer does not work this way a lot of cache and memory, common type of printer use more of this work. Another is to transfer the data stored in the printer's internal hard drive, ready to be printed out when used, also known as the "pool work," many high-end printers to use this work. The advantage is that when many users share a printer, which can issue print commands without having to wait, and save data communications transmission latency, but its price is more expensive. cell phone jammer can effectively manipulate the turning over of the multimedia files.
Laser printer to print out the text or images, if observed under a magnifying glass, you will find a lot of text or images from the white point and black dots (also called raster graphics), and the common dot-matrix printing is similar. The former is by controlling the laser beam on and off to achieve lattice arrangement, while the latter is achieved by hitting pin dot matrix printing order. Raster image is a digital video image, you need the printer's raster converter to be rasterized video data, into the use of dot matrix printers print images, the so-called raster image is formed by an independent point of the image. Such as newspapers or television screen printed image is on display raster images. Laser printers dot matrix arrangement is formed by the binary data matrix control, each point corresponds to a binary digit, the operation controller controls the laser beam to the photosensitive drum surface injection laser, known as "exposure" was the exposure of "point "called" pixels. " Work to solve these problems in great help. Especially the maintenance staff, if not fully understand the working principle of laser printer parts and functions, it would not "maintenance" word. cell phone jammer has been becoming popular since they first appeared on the market.
This is the early optoelectronics. With the development of optoelectronics, people study the full use of light to process information, so the birth of photonics. So it can be said, first with the optoelectronics, photonics, there has been. The final development will be re-unified optical, that is a higher level of optoelectronics. Is now developing a single electronic technology and single-photon technology, when the information carrier is no longer the beam, but the individual particles. Photons and electrons are the concepts of quantum mechanics, the difference is just a different wavelength.
