The HP printing system—printers, toner cartridges, HP toner and paper—is engineered to work precisely for optimal quality and reliability. As a vital component, every HP cartridge must meet strict quality standards. For example, to validate ease of use and consistent print quality, we test every HP LaserJet toner cartridge design using hundreds of prototypes. This includes testing the cartridge as an integrated system with the printer. The result—consistent quality and reliable performance.
