A laser printer is a common type of computer printer that produces high quality text and graphics on the paper.
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, colour 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.
