As the name implies, inkjet copiers/printers use a liquid ink to produce an image. A laser copier uses a dry powder called toner to produce an image. These two materials are also applied to the media via different processes. The inkjet uses an array of micro nozzles to spray the ink onto the media where it dries. The laser process uses a series of static charges to transfer toner to the media and then applies heat to melt or fuse the toner to the surface of the media.
