LASER PRINTING
The primary principle at work in a laser printer is static electricity, the same energy that makes clothes in the dryer stick together. Static electricity is simply an electrical charge built up on an insulated object, such as a balloon or your body. Since oppositely charged atom are attracted to each other, objects with opposite static electricity fields cling together.
A printer uses electrostatic charge to direct the tiny ink droplets to the correct place on the page. The direction in which the charged ink droplets move can be controlled by electrically charged metal plates. A voltage on the plates means that the charged ink droplets will
be attracted to one plate and repelled by the other. By controlling the voltage on the plates a particular ink drop can be precisely positioned on the paper. There are many nozzles, and the final picture is made up from a very large number of coloured ink drops, each in exactly the right place for the image.
