The result is bold graphics and realistic images that enable photo-quality business printing.

Documents come off the printer quickly without sacrificing quality. HP LaserJet ColorSphere toner particles are scientifically developed around a perfectly-sized wax core designed to work with HP’s instant-on fusing technology for faster image processing with optimum results.

HP 643 LaserJet Printing Supplies with HP Smart Printing Technology * enable the cartridges and the printer to make continuous adjustments that optimise print quality and reliability - and provide a lower overall cost of printing.

For consistency over the cartridge's life, HP Smart technology * in HP supplies and the printer relies on the unique properties of HP ColorSphere toner.

HP supplies and the printer work together to ensure the quality of each print, saving time and providing real value.
