Our customer can buy the products of green laser pointer with more confidence and use them with more comfortableness. Whether it is black and white laser printer or color laser printer, the basic working principle is the same, they have adopted a similar electrostatic copiers photography, prints the contents into a drum on the lattice in units of pixel bitmap image, and then transfer onto the printing paper to form the content. The only difference is that with the light source copiers, copiers using ordinary white light, and laser printers use a laser beam. In the laser printer, the print controller's role is with a computer or network to communicate through the interface, the receiving computer to send and print control information, transmitted to the computer while the printer's status. Print engine controller will receive under the control of the print content to transfer onto the paper. 24-hour after service hotline support and network support are available to 200mW Laser Pointer ...

Therefore, the print controller and print engine performance and quality affect the whole printer performance and quality, which is currently on the market using the same laser printer engine performance differences appear important reason. All of the print controller is a full-featured computer, it basically includes a communication interface, processor, memory and control interfaces four basic functional modules, some of the high-end model also features a large capacity hard disk storage. Responsible for computer communication interface for data communication; memory to store the received print information and explain the resulting bitmap image information; control interface is responsible for the laser scanner engine, motor and other components of the control and the printer control panel input and output information ; The processor is the core of the controller, all data communications, image interpretation and the engine control by the processor. The object of low heat resistance should keep away from 100mW laser pointer.

Because the printer control mode and control the use of different languages, the print controller configuration and performance requirements are also different, such as the use of PCL and PostScript printer language, the computer and the printer uses a standard page description language for printing information transmission, in the printer from the computer you want to receive the standard language to describe the use of print information print engine can be interpreted as a bitmap raster images to receive information, print controller performance and memory size will direct the performance of the printer impact, so this printer on the print controller's processor speed and memory size required is very high. The GDI printer with the printer page description language used is different in the printing process, print the contents of the computer to complete the raster bitmap image information to explain directly to the printer, so in the printer controller is mainly store the received raster bitmap images, and control the print engine to complete printing. Since no complex image interpretation bear, GDI printer on the print controller's performance is relatively low. Blue Laser Pointer might be damaged during shipping process.

The structure is shown in photo printing engine, which includes a laser scanner, the reflector, drum, toner cartridges, thermal transfer paper feed unit and institutions of several major components. From a functional structure, laser printers print engine and print controller is divided into 2 parts. Laser printers print engine from Canon, Minolta, Xerox, Brother, Samsung, Hitachi and other manufacturers offer a few engines. The printer manufacturers are tailored to the engine manufacturer to purchase or print engine controller according to engine design and print drivers to complete the printer's design and production. This is the form the field of laser printers print engine and print the whole two reasons for the market. Laser printer is the most important component drum, that organic image transmission organizations (referred to as OPC), the entire printing process is to drum center, again and again to the action. Black and white laser printers work can be said that the whole process of charging, exposure, imaging, transfer images, fusing, clear, and in addition to the seven steps of the cycle as such. Printers are peripheral devices, requiring cooperation with the computer to print. In the non-network environment, usually between the printer and computer through a printer cable connection, this cable is connected to one end of the cable to the printer interface, and the other end connected to the computer's printer port, such as LPT1. 5mW laser pointer has passed the strict testing.

However, in a network environment, the printer more through a dedicated print server to connect to the network. Connection of the two biggest difference is the print data transmission speed: When connected to the network through a print server, the print data transmission speeds faster than cable by printing a few hundred times. Charge in the drum with a shield near the corona wire, when the drum starts to rotate, the high voltage power supply of its addend kV high-voltage, corona wire corona discharge began, this time, the corona wire around the non-conductive the air is ionized into a conductive conductor can make the drum surface to bring positive (negative) charge. When the computer to the printer the print command, the first printer languages these data need to "translate" the data into the printer will be able to read it to understand language. This "translation" process is done by the printer language. Indices and technologies of green laser pointerare of the world advanced level.
