These printers employ a xerographic printing process which differs from the analog photocopiers in which the images are produced by the direct scanning of a laser beam across the printer's photoreceptor. Unlike impact printers, laser printers can print over 200 monochrome pages per minute and the fastest colour laser printers can print over 100 pages per minute. These fast printers are mainly used for mass mailings of personalized documents such as credit cards and utility bills.

The cost of this remarkable technology depends on various factors such as cost of paper, toner and sporadic drum replacement, only the printers with soft plastic drums can be a little expensive. An easy way to reduce the paper costs and filing volumes is to have a Duplex Printer; a printer that prints on both sides of the paper.

Unlike the typical black and white laser printers, add colour tone to the matter being printed. To sanction high registration accuracy some colour laser printers use a large belt to generate the image. All the four layers of the toner CMYK, i.e.: cyan, magenta, yellow and key (black), are precisely applied to the belt, and the combined layers are then applied to the paper in a single step.

The laser printing process mainly includes 7 steps to process an image, once the image generation is complete the printing process starts which permits the use of a very small and compact unit, where the photoreceptor is charged and the entire process can be completed before the drum completes one revolution .This colored laser technology is also helpful for the government, in case of tracking down some important documents. This is done by flashing an LED flashlight beam on the printer which will create a few small, scattered yellow dots which could be used to trace the documents back to you.

Therefore, after the standard laser printers, colored laser printers have definitely created a colour revolution. This leading edge technology is easy to use which enables the customers to concentrate on outstanding results.
