The design details of the print cartridge/s used in HP LaserJet printers differs between printer models to reflect the different customer needs being addressed by different printer models. For example, a LaserJet monochrome printer can have a different cartridge design than an HP color LaserJet printer. Color printing is more complex than monochrome printing and the cartridges used in color printing can differ significantly between different HP color printer models. These design differences are driven by HP's goal of delivering the best value, printing experience and outstanding print quality for a variety of customers who have different printing needs.
HP designs its LaserJet printer systems to deliver outstanding value and print quality over the life of the printer. In order to accomplish this, the LaserJet printer system is made up of the printer itself and the HP LaserJet print cartridge/s. These print cartridges (which are sometimes called 'toner cartridges') contain far more than toner. These print cartridges are complex multipart systems, one part of which is toner.
