(1) data translation: in order to print complete words and images, in addition to the function of the laser printer itself, the content to be printed must be edited into a computer language with a certain format by using a word or image processing software or graphics processing software. The content described is determined by computer editing software and has nothing to do with Thermal Portable Label Printer Manufacturer. When we select the print command, and determine the print button, the computer sends the edited data through a printer interface to a printer, the printer driver to print the content of explanation, and change printer can identify the language (language) is also called the printer, the printer to print out has been edited according to their own language text or image.
Different types of Thermal Portable Label Printer use different drivers for different printing languages. There are also compatible printer drivers. Production of laser printers, commonly used standard printing language PCL5 or PCL6.
(2) data transmission: there are many communication ports between the printer and the computer, and the common one is "serial port" or "parallel port". EP P/ECP (KIOSK Printer China) is referred to as Enhanced /Extended parallel. "Serial port" is seldom used because of its slow speed. Others, such as the SCSI interface, are mostly used on higher-end printers because of their speed. Other printers communicate with computers using the video interface (VDO), which is different from other interfaces. Its data is done by another "video conversion card", but because it shares memory with the computer, the computer is required to have enough cache space. The general printing typesetting industry USES this interface printer more. Some high-grade printers have multiple interfaces and can connect multiple computers at the same time. Many of these Portable Printer Supplier come with faster USB ports.
When the printing controller receives the data from the computer, the printer generally adopts two ways of working: one is to send the data directly to the interpreter for printing, which is called "segment working mode". Printers that work in this way do not need a lot of cache and memory. Ordinary printers usually work in this way. The other is to store the transmitted data on the internal hard disk of the printer and print it out whenever you need it. The advantage is that when many users share a printer, they can simultaneously issue a print command without having to wait and save the waiting time for data communication, but it is also more expensive.
Photosensitive drum is the core part of laser printer. Panel Receipt Printer is a photosensitive device, mainly made of optical materials. Its basic working principle is the process of "photoelectric conversion". Small Portable Receipt Printer is used as a consumer material in laser printers, and it is also relatively expensive. Photosensitive semiconductor has the common character of semiconductor, if be stimulated by heat, after doping, change electrical conductivity. In addition, it has a "photoconductive" property that no other semiconductor has. The conductivity of a photosensitive semiconductor can be increased by several orders of magnitude when exposed to light. In terms of energy bands, electrons in its valence band absorb the energy of light and jump into the conduction band, producing electron-hole pairs. This pair of electron-hole pairs produced by light is called "photo-borne carrier". As the number of "photo-generated carriers" in a photosensitive semiconductor increases, its electrical conductivity increases. This improved conductivity after exposure to light is called "intrinsic photoconductivity". In practice, the photosensitive semiconductor material needs to be doped before it can be made into the semiconductor material used in laser. Therefore, in addition to the intrinsic photoconductivity, Portable Printer Supplier is also necessary to have the properties of the impurity photoconductivity formed by electrons or holes on the photoexcited impurity level. In some photosensitive semiconductors, "impurity photoconductivity" plays a major role.
The "carrier mobility" (Portable Printer China) in an object can be changed to different degrees after being irradiated by light. The "conductance" that marks an object's ability to conduct electricity is equal to carrier density times mobility. Mobility is increased, conductivity is improved, and conductivity is determined by the values of intrinsic photoconductivity, impurity photoconductivity and mobility, but under certain conditions, some of the factors are the main factors.
All kinds of optical conductors used in practice have different sensitivity to light. The conductivity of a photoconductor is directly proportional to its sensitivity to light. So the optical inductance of a photoconductor is very important. Light conductors have different sensitivity to light. A light conductor that is sensitive to only the light of a particular region of the spectrum may lose its light sensitivity if it leaves that region.
A photosensitive semiconductor forms an absorption peak for light in the range of light wavelengths suitable for it. Photoconductivity is best in this peak range. It also has to do with illumination. The higher the illumination, the more carriers produced, the higher the photoconductivity. However, each optical conductor has different characteristics, so the illumination required to achieve the same photoconductivity index under the same conditions is different.
The common photoconductive materials used for photosensitive drum are cadmium sulfide (CdS) and Se-As. Organic photoconductive material (opc), etc.
POS Printer Chile were born out of laser phototypesetting technology in the late 1980s and became popular in the mid 1990s. It is a Bluetooth Printer China output equipment combining laser scanning technology and electronic photography technology. Its basic principle is from binary data by computer information, through the video controller is transformed into video signal, again by video interface/control system, the video signal is converted into a laser drive signal, and then produced by the laser scanning system with character information of laser beam, finally make the laser beam by the electrophotographic system imaging and transfer to the paper. Compared with other printing equipment, the laser printer has the advantages of fast Printer Manufacturers speed and high imaging quality. But the cost is relatively high.
The composition, design structure, control methods and components of the control devices and components required by the working process of laser printers will vary from manufacturer to manufacturer.
Mini Portable Printer a laser beam, the mirror into the acousto-optic deflection modulator, at the same time, by the binary from computer graphic dot matrix information, from the interface to the glyph generator, form the glyph of binary pulse information needed, produced by synchronizer signal control 9 high frequency oscillator, then through frequency synthesizer and add to the acousto-optic modulator, a power amplifier for modulation by mirrors into the laser beam. The modulated light beam is shot into the multi-facet rotation mirror, and then it is focused by the wide-angle focusing mirror to the surface of the optical drum (toner), so that the angular velocity scan becomes linear velocity scan, and the whole scanning process is completed.

Inkjet printer
The basic working principle of Small Portable Receipt Printer is to first produce small ink drops, and then use the inkjet head to guide the small ink drops to the set position. The smaller the ink drops, the clearer the printed picture will be. The fundamentals may seem simple, but they're not that simple. Just as the principles of calculus are not complicated, complexity is how to apply them. The following describes several technological breakthroughs in inkjet printers with historical significance.
The printer was co-invented by John walter and Dave Donald. A device that prints the results of a computer's operations or intermediate results on paper in a prescribed format, in Numbers, POS Printer Brazil, symbols, graphics, etc., which a person can recognize. The printer is developing in light, thin, short, small, low power consumption, high speed and intelligent direction.
With the rapid development of the Internet, some people predict that the paperless era is coming and the end of the POS Printer Kenya is coming. Yet global paper consumption is growing at multiple times a year, and printer sales are rising at an average rate of nearly 8%. All this suggests that printers will not disappear, but will grow faster and faster, with a wider range of applications. From 1885, the world's printer, and then all kinds of needle Mini Portable Printer, inkjet printers, and laser printers, they are in different s the excellences, today let's look for the tracks of history, from technology, brands and products, application market and target customers from three aspects, review the brilliant history of the POS Receipt Printer Driver, at the same time to spray the future trend of the development of a simple analysis.
There are many Printer Manufacturers products on the market, but relatively few bluetooth printers. A bluetooth printer, is refers to using a single chip microcomputer to simulate the printer on the host end work, intercept from the host from the parallel data and control signals, and transmitted via bluetooth wireless connection to the Small Portable Receipt Printer. The single-chip microcomputer on the side of the printer simulates the host computer to control the printer according to the received bluetooth data, thus realizing the bluetooth wireless connection between the printer and the host.

Fast transmission speed
Compared with infrared and other methods, bluetooth transmission protocol has obvious advantages in speed. The maximum speed of bluetooth 4.0 theory reaches 24Mbps.
Although there are many advantages, the bluetooth transmission protocol, like other 2.4g devices, shares the signals of this frequency band, which inevitably leads to interference between signals. In addition, the bluetooth protocol is not a free technology, and Portable Receipt Printer manufacturer using the technology will have to pay a royalty fee to the organization, which will be included in the cost.
Panel Printer China is the application of bluetooth technology on the printer, get rid of the Panel Mount Thermal Printer connection, the inconvenience of wirelessly print, can reduce the unpleasant cables on the desktop, and the printer can be far away from the host move, put in the room is suitable for the position.
Bluetooth is a low cost and high capacity short-range wireless communication specification. A bluetooth laptop is a laptop with bluetooth wireless communication function. The name bluetooth is still a legend. In the 10th century, when the vikings of northern Europe were fighting for supremacy, the king of Denmark stepped forward. Through communication, the vassals resolved their differences and became friends. Because the king of Denmark loved eating blueberry so much that his teeth were dyed blue and he was known as the king of bluetooth, bluetooth became a synonym for communication. A thousand years later, when the new wireless code was introduced, people named it bluetooth. In 1995, Ericsson came up with the concept of bluetooth. The bluetooth specification USES the microwave frequency band to work. The transmission rate is 1M bytes per second and the KIOSK Printer China. The transmission power can reach 100 meters by increasing the transmission power. Bluetooth technology is a global open, on a global scale has good compatibility, can lower the cost of the world's intangible bluetooth networks into an organic whole of bluetooth nature has been sending out the glamour business performance and portability. With the popularity of camera phones, bluetooth almost become the standard of modern mobile phone, people demand for photo print function anytime and anywhere has appeared, and based on bluetooth wireless printing is the best solution, more and more printer manufacturers launched a photo printer with bluetooth technology. Bluetooth technology costs more than infrared, but it also has higher performance. The transmission speed is more efficient, the distance is far, and it is not limited by obstacles. At the same time, it has good safety performance and strong anti-interference ability. The use of bluetooth technology printers can greatly improve office efficiency, so that office equipment can be connected without cables. Using a camera phone with bluetooth technology, you can also easily start wireless printing, convenient and fast.
Many companies because of not familiar with Thermal Portable Label Printer, in choosing a bar code label printer often don't know how to choose, so users should be how to choose to suit oneself enterprise use bar code label printer? Here, the choice of printer to provide customers with a few basis. When selecting a barcode label printer, the following issues should be considered:
If you print more than 1,000 labels a day, you'll need a high-volume industrial printer with a solid metal case, such as SATO CL408e/412e, CL608e/612e, etc. If the printing quantity is small, the desktop personal printer series, such as ct-400/410, can be adopted. The desktop personal printer series, such as POSTEK Q8 series, POSTEK C168 series, POSTEK G2108/G3106, Zebra S400, S500, can be selected at the point of sale or office.
Tag size
The standard barcode printer can print 4 "X6" labels, which is in line with the current shipping label specifications. You can also print labels of different sizes flexibly according to your own needs. For wider labels, choose CL608e/CL612e.
Tag content
If you only need to print barcodes and text, a normal barcode label printer can do it. But if you need each KIOSK Printer China different bar code, such as item number or text (such as shipping label), and don't want to stop halfway to print, you will need a printer of 32-bit processor, which can greatly improve production efficiency.
Quality of label
The printing resolution of label printer is generally divided into 203dpi, 300dpi and 600dpi. The larger the dpi, the better the print. If you want to print a high quality image on the label, you may want to choose the Panel Mount Thermal Printer head of 300dpi.
Print speed
Different types of printers have different printing speeds, depending on the user's requirements for speed. General print bar code label printers, label making machine speed is 2 "to 6"/SEC per second, and the bar code label printer with higher speed, such as M8400RVe printing speed can be up to 10 "/ SEC, if need to print in a short time a large number of labels, you should choose the bar code label printer
Application in different industries
The bar code printer used in the production line or in the warehouse should choose a model with a metal casing, such as SATO408e/412e; The desktop personal printer series, such as ct-400/410, can be selected in the sales point or office, because less space is needed and it is easy to move.
