How Laser Printer works?
It is quite complex to bring the working method of laser printer in detail but a basic idea behind it, is written below.
A laser printer consists of drum (a photoreceptor assembly), corona wire, discharge lamp, toner hooper, fuser etc. at first drum is loaded with positive charge by means of corona discharge and as drum revolves a laser beam is brought on the surface of drum which creates negatively charged invisible electrostatic image of letters or pictures to be printed.
System will not be affected if charge is reversed i.e. drum is initially loaded with negative charge.
After this printer spreads positively charged toner over the drum which adhere to the negatively charged portions of the drum, after this pattern is fixed a negatively charged paper (it is also charged by corona discharge) rolls over the drum which attract the positively charged toner which ditto the image on the paper. To avoid the sticking of paper with drum it is discharged by detac corona wire. At last paper passes through the heated fuser which melts the toner and fused it with the paper by means of pressure. Speed of paper through fuser is maintained such that it can pass up without catching fire. Mean while a bright light emitting from discharge lamp clean the electrical image formed on the drum and drum get ready to print next page.
Mono PrinterMono printers are small printers which only print black and white.
Network PrintingWhen multiple users use the same printer for the printing then this printer has been connected by the network and this network is called Network printing

TonerToner is only used in laser printer and photocopiers. Toner is a powder which is used to print taxt as well as images. The powders are melted by the Fuser then bind onto the paper. The standard Colour in which toner is available: obviously CMYK.
