Among the printers, if we disregard the very exotic technology transfer images from your computer, there are two large families who get along well with each other and are not intended to place each other, at least until the next time. The first family – laser printers, the second jet. What is a laser printer?
The principle of operation of these printers is based on the property of an electrified drum to transfer the powder (toner) from the cartridge to the paper. The toner is transferred only in those places where the drum charge remained and were not removed periodically runs through the drum by a laser beam. The transferred powder is then hot rolled and baked rolls on the paper by heat.
A characteristic feature of laser printer technology:
– Special black and white printing. – Large print speeds. – Long life of the cartridge, in which a filling is enough for a large number of pages printed. Resource laser printer cartridge may be ten times longer than an inkjet cartridge.
Disadvantages of Laser Printers:
– Bad color rendering. Laser printers are available for purchase and use at home can not pass all the colors due to the fact that a satisfactory color reproduction can not be achieved because of the characteristics of the toner and limitations of the technology. The toner can not be uniformly mixed prior to application, because applied to the paper for each line of the same color, and the qualities it is opaque. – Relatively large power consumption during preparation for printing and printing process itself. It is caused by the necessity of heating the sheet after application of toner on it. – Low resolution compared to inkjet printers. which can make multiple passes by the printhead, it displaces each time by a distance that is less than a print point.
The ink or laser printer consumables – toner, black or colored powder.
