Do laser printers print with color and how does it work?

please to describe this dont use big words. and i also want to know more info on ink jet printersDo laser printers print with color and how does it work?
Yes laser printers can print colour.





Basically a laser printer uses toner which is a powder. There will be a drum (a round cylinder) on the inside of the printer that is statically charged ( like rubbing a balloon on your head) and the powder based toner will be attracted and statically cling to it.





The purpose of the laser is to basically draw on the drum what needs to be printed. When its drawing on the drum its charging or uncharging portions of the surface of the drum so the powder will staticly cling to the parts that need colour and won't to the places that don't.





Inside the printer there will be 4 different colours of toner; cyan magenta, yellow and Black. The printer will combined those 4 colours in different amounts to give you lots of colours.





Once all of the toner is in place on the drum the paper will come and will be given a charge that is stronger then the drum. The paper will pass under the drum and since its static charge is greater then the drum the powder will jump onto the paper and stick as it passes by.





Once the paper takes all of the toner as it passes the drum it will move into a part called a fuser which are hot rollers which melt the loose powder that was only being held on by static. When the powder melts it bonds into the paper.





Inkjet uses a liquid ink of the same 4 colours, cyan magenta yellow and black (some can have more to give you even more colours). An inkjet will basically feed a paper in a little bit at a time.





It has a nozzle with tiny holes which will spray ink dots and when combining all the 4 colours gives you many colours. The nozzle will move from side to side like a typewriter. It will spray ink onto the paper from one side to the other then inch the paper forward a little bit and continue with the next line until its complete.





Hope that helps,

you can get colour, or black and white laser printers.


They are usually intended for commercial use, as they are faster and produce better quality print than home printers such as inkjet.


Laser printers use toner cartridges which can be VERY expensive - inkjet refills are very much cheaper - check them out on Ebay.





There is an excellent article all about laser printers on Wikipedia - see below
If you buy a color laser printer, then you will be able to print color. Color laser printer is much expensive than black-white one, because it usually use 4 cartridges-- 1 black and 3 color-- that's why laser color usually don't used by homer users.
When i was studying for my A+ cert, I used this website and videos for studying it will talk about the laser printers
