The major difference between copiers and laser printers is the way the image information is transmitted. Laser printer transmission is sent through a laser beam that passes the information directly to a receptor. Copiers work through a set of lights and lenses that adjust during the process in order to pass the right information to the printing drum. Simply put, copiers scan in order to print, whereas laser printers receive the input in digital form. When we use the word printer, we also mean copier. Nowadays, most people print rather than copy.
