The new function of china laser pointer includes the pageup or pagedown function

Color LaserJet structure: four imaging Color LaserJet constructs: an imaging while color laser printers, black and white laser printers, the biggest difference is in the engine structure, color laser printer using C (by Cyan, blue), M (the Magenta products red), Y (Yellow, yellow) and K (Black, Black) 4-color toner to achieve full-color printing, a color content of color to go through the CMYK to reconcile, a content of the print to go through the CMYK 4-color toner printing process 1. In theory, color laser printers have four sets of identical bodies with black-and-white laser printers to achieve the color printing process. The teachers can remotely control the PPT they use in the class through using    green laser pointer.
The print controller, the internal processor speed higher than the black and white laser printer, the configuration memory than the black and white laser printer. The laser printing technology of the mainstream is complicated, we do not need to eleven to explore the principle, let's print speed, resolution, color processing technology to understand some of the major representative of the technology. Print speed of technological innovation Resolution technological innovations color to deal with technological innovation CoLorSmartII color engine technology Tandem high-speed operation at the same speed imageRET2400 fine control intelligent color dots second-generation technology system technology technologies technique II Levels expansion of technology 1. It will be the situation for the lecturer, reporter or business men when they carry out their lecturing, reporting or presentation in the meeting room, concert hall or trade meeting by using    laser pointer  .
Color print speed of technological innovation color same speed technology HP same speed technology, which is an imaging technique, the four colors has its own imaging drum, at the same time, the inner four imaging drums, respectively showing four colors electronic images, and adsorption of the respective colors of toner to the latent image to form four different colors, paper followed by the four colors of the "latent image" transfer to the print media, and finally to achieve fixing by the fixing roller due to the color once printing is complete, rather than four times the color printing performance is greatly improved, and color print speed black and white print the same. Tandem high-speed engine of this technology is given full play in the Epson Aculaser C4100 color laser printer.  green laser  also has the modern functions of the wireless presenter.
Advanced 4-2-1 tandem (Tandem) print engine, CMYK four color to imaging, print speeds four times faster than traditional color laser printer speed, efficient output of 24 per minute black and white color with the speed . Two. Resolution of technical innovations resolution technology innovation imageRET2400 technology imageRET2400 technology, also known as image resolution enhancement technology, here we the HP ColorLaserJet4500 color laser printer, for example, it uses HP's patented ImageRet2400 color layering technology, the engine 600dpi physical resolution of the basis on the particle diameter as small as 5 microns the UltraPrecise ultra-fine toner. The new function of   china laser pointer   includes the pageup or pagedown function.
Multilayer coloring, 2400dpi effect on each physical pixel. Maximize integration into the printing process in a single point in four colors, and allocation of the toner in the designated areas, to achieve precise control of color, resulting in hundreds of thousands of soft colors. Fine ink point control technology Epson AcuLaser Fine ink point control techniques used in the exposure unit by changing the pulse width to control the time of the laser emission. Precise control of pulse width allows the printer to be able to control the size of the dots. Therefore, the technology can copy a smooth gray scale, even in the bright and dark areas. Of course, the lecturers can use  green laser pointer  to point at the content they want to highlight.
