How does a laser printer work?

1. data to be print is sent to printer driver, printer driver checks that data is understandable and printer is available to carry job out 2. data is sent to printer and stored in printer buffer 3. Printer drum in printer is given a positive charge. Laser beam removes charge in certain area, leaving negatively charged areas which match character to be printed 4. the drum is then covered with positively charged toner (powdered ink) which sticks to negative charged areas 5. negatively charged piece of paper rolled over the drum, causing toner to stick on paper, negative charge is then removed 6. paper goes through the fuser,which melts ink onto paper.
