Advantages
The main ADVANTAGES of using a laser printer are it is quick at producing high quality images, it is precise and also it is very economical, it has a very low noise output and many off the printers are lightweight and compact so they dont take up much space on a desk.



Disadvantages
The main DISADVANTAGES of using a laser printer are the cost becasue cartridges are more expensive then the cost of inkjet printer's toner, and printing time is longer so it would be less efficient at printing a lot of work in one go.

Inkjet Printers

An inkjet printer is a type computer printer that creates a digital image by propelling variable sized drops of ink on to paper. Inkjet printers are the most commonly used type of printer becasue of ther low maintenance fees and inexpensive consumer models to very large professional machines. when inkjet printers started out they were used becasue they were able to print the digital images generated by ther computers.



Advantages
The main advantages of inkjet printers are that they are cosiderably cheaper to buy, high end printers are capable of producing good quality images when used with special paper and that most models are relatively light weight and compact so they don't take up too much space on the desk.




Disadvantages
The main disadvantages of inkjet printers are due to the cost of ink running and inkjet printer can be more expensive than a laser printer, prints emerge from the printer slightly wet and may need time to dry and printing is slower and therefore inkjets aren't designed for high volume printing.


How does an Inkjet Printer work?
At the most basic level, what the printer does is place small drops of ink onto the paper. Inkjet printers are considered a type of non impact printer, as opposed to dot matrix, since the ink is transfered to the paper by way of nozzles. These nozzles spray the ink directly onto the paper.
