So you get the final printed page. In addition, the fuser will be the paper itself to heating, this is from a laser printer or copier paper is always hot reasons. Paper, why did not ignite? The main reason is speed - the paper is pulled through the roller speed quickly, so the temperature does not become very high. Toner printed onto the paper surface of the cartridge will go through the discharge lamp. This light is very bright lights to make the entire photoreceptor surface is exposed to light, in order to wipe the static image of the above. Then, the surface of the cartridge after the charge corona wire, and once again bring a positive charge. So that the laser of green laser can be used in some specific locations.
Conceptually, all the work of the laser printer is one such. Of course, these different components actually closer together is a complex task. In a later section, we will be more detailed description of the various components to see how they produce text and images quickly and accurately. Printer Controller: communication. Laser printer to work, it needs to get the page data and figure out how these data printed on paper. This work is done by the printer controller. The printer controller is the laser printer's main onboard computer. Through a communications port (eg, parallel or USB port) and the host (such as your PC) to talk to. Especially when the power of the laser beam light of green laser pointer is large enough, it will be even more dangerous.
In the beginning of the print job, the laser printer with the host to determine the exchange of data. The controller may have to periodically start and stop the host in order to deal with the information it has received. Typically, laser printers with a number of different types of communication ports. In the office, laser printers may want to connect to multiple hosts, multiple users can print documents from their own computers. Controllers to handle each user's print job, but may also carry out a lot of "dialogue". Ability to handle multiple jobs simultaneously is one of the reasons why laser printers has been widely welcomed. Printer languages. To enable communication between the printer controller and the host. It is during operation and disposal of the laser beam light of green laser pointer .
They need to use the same page description language. In earlier printers, the computer sends a special text file and the printer provides a simple format of a simple code. Because these early printers only a few fonts, so the above process is a very simple process. Now, you can choose hundreds of different fonts, and print a complex image and without hesitation. In order to deal with a variety of information of all these changes, the printer needs to be said a more advanced language. At present, the Hewlett-Packard's Printer Command Language (PCL) and Adobe Postscript printer language. Both languages - that is, the page description for the mathematical value of the geometry of the vector form description page. green laser pointer has the high quality and high performance and parameter and at the same time the lower price.
Best described not as a series of dots (bitmap images). The printer received vector image, they will be converted into a bitmap page. Using this mechanism, the printer can receive elaborate, complex pages, and print out any type of font or image. In addition, because the bitmap image is created by the printer, so it can use a maximum resolution of the printer. Some printers use the Graphics Device Interface (GDI) format instead of a standard PCL. In this system created by the host lattice, so the controller does not undertake any treatment - it's just the point of instruction sent to the laser. But in most laser printers, the controller must organize all the data it received from the host. green laser pointer is visible and especially clear in the dark night.
