how laser printer works
A laser printer is so called because it uses a laser as part of its core function. A laser printer is generally considered to be more accurate and also faster than an inkjet printer, making it a more favorable, but also more expensive, alternative. Information is sent from a data storage component, contained within your PC, to an image processor within your laser printer. The processor takes information from your PC as its input and outputs data which is suitable for printing. Contained within the printer is a light sensitive component which makes contact with an electronically charged component that causes negative, static, electricity to be produced. The static electricity will remain until light is applied on it, which will cause it to disappear. Light is then reflected, with the use of mirrors for accuracy and precision, onto where toner will be applied. This allows the toner to stick to the paper and not smudge or spill onto parts that it should not.
