Brief discussion of laser printer

** Hello steemit friend today I am going to write about the working procedure and advantage of laser printer..... **

• The line Dot Matrix and ink jet printers need a head movement on a ribbon to print characters. this mechanical movement is relatively slow due to the high inertia of mechanical elements.In laser printers these mechanical movements are avoided....

• Indies printers and electronically controlled laser beam dresses out the desired character to be printed on a photoconductive drum....

• The exposed area of the drum gets charged, which attracts and oppositely charged Link from the ink donors on to the exposed areas. this image is then transferred to the paper which comes in contact with the drum with pressure and height. The picture given below....

• The charge on the drum decides the darkness of the print. when charge is more more ink is attracted and we get a dark print....

• A colour laser printer works like a single colour laser printer, except that the process is repeated four times with 4 different ink colours: cyan,magenta, yellow and black. laser printers have high resolution from 600 dots per inch up to 1200 dots per inch. These printers print 4 to 16 page of text per minute. The high quality and speed of laser printers make them ideal for office environment.....

Let's talk about the advantages of laser printer:

• The main advantage of laser printers are speed precision and economy.

• A laser can move very quickly so it can write with much greater speed.

• It's toner power is cheap and lasts for longer time.
