    A laser printer uses a laser beam as a core component of fulfilling its functionality. A laser printer is generally considered more accurate in its rendering and also capable of printing at much quicker speeds compared with inkjet printers. Firstly data is transmitted from the data storage device, or the computer, to the image processor which is usually contained within the printer itself. The image processor is capable of migrating the data it stores into graphical format before sending it to the memory contained within the printer to allow for transmission to occur. The photosensitive, or light sensitive, drum revolves and touches the corona wire, or the charged roller, which causes static electricity to be produced. This static electricity will remain on the drum until light causes it to disappear. At this stage light is reflected on to the rotating photocell, which removes the negative static charges, allowing the image to be represented where there is a positive electronic force. Now the printer is able to transfer toner onto the paper, which depicts the previously digital image in a hard copy.

    For a detailed explanation, see

    Briefly: A drum is charged up with electrostatic charge. The laser then writes the image onto the drum, discharging the bits where it shines but leaving the remainder still charged. Toner is then put on the drum, and sticks where the charge remains, but falls off where the laser has discharged it. Heat and pressure are th4en used to transfer this ink to the paper and fuse it on.
