The design of green laser pointer has been put forward in the meeting

Drum in the process of using the printer to be recharged, and thus should have good fatigue resistance, within the specified life time, the print quality does not decline due to continuous use. Photoconductive properties of the drum stability is better, shall meet the requirements of continuous use. The laser printer drum, usually three-tier structure. The first layer is the aluminum alloy cylinder (conductive layer), the second layer on the cylinder surface by vacuum evaporation method, coated with a layer of photoconductor materials (photoconductive layer), the third layer is the outside of the photoconductive material plated with a layer of insulating material (insulating layer). Some drum in order to release the charge, in the middle of the photoconductive layer and the aluminum conductive layer, plus the plated layer of superconducting material to allow for more rapid release of charge. The customer is very interested in the design of  green laser pointer .
Insulating layer of the photosensitive drum surface, one to improve the wear resistance, increase the service life; provide protection for the photoconductive layer to prevent the wear of the photoconductor, to maintain the photoconductive characteristics of photoconductor. Ground of the conductive layer of aluminum alloy tube with a laser printer connected to the potential rapid release after exposure. It is a very high precision cylinder, and the operation of the process, able to maintain uniform operation and maintain a uniform charge. Laser printers, data translation and transmission data translation: To print the complete text, images, in addition to the function of the laser printer itself, but also through the computer to print the contents of text or image with a word processing software or graphics software and compiled a computer language with a certain format. The customer is well satisfied with the design of  green laser pointer .
Its description of the contents are determined by the computer editing software, has nothing to do with the laser printer. When we selected the printer command, and press OK to print button, the computer edited data sent to the printer through the printer interface, the printer driver to print the contents of the interpretation of the language of the printer can recognize and convert it (also called printer language), text or image has been edited by the printer to print out their own language. Different models of laser printers, print, different languages used by the driver is also different. Of course, there are a compatible printer driver. Now the production of laser printers, the general standard print language PCL5 or PCL6 language. The customer is checking the new design of  green laser pointer .
Data transfer: the printer and computer communication between the transmission port there are many more common is the "serial" or "parallel port". EP P / ECP (Enhanced ParalleI Port / Extended Capabilities Port), referred to as enhanced / extended parallel port. "Serial" slow, it seldom used. Other interfaces such as SCSI, fast, mostly used in more high-end printer. Some printers use the video interface (VDO) way communication with the computer, communications and other interfaces to send it, not data, but the laser beam, faster. Data is accomplished by the addition of a "video conversion card, but it shared with the computer memory, the computer has enough buffer space. The customer thinks that the design of  laser pointer    should be further improved.
