HP Color LaserJet 4500 toner cartridges and supplies ensure that you always get optimum color output with your HP Color LaserJet 4500 Series printer. For example, some toners are mechanically ground, which produces a faceted toner particle. However, HP's chemically grown color toner particles are spherical in shape and extremely small in size, resulting in uniform color density and exceptional print quality. What's more, HP's high-yield toner cartridges reduce waste and require less interaction, with cost savings of up to 27% over competing products. The affordable price of HP LaserJet color supplies makes it cost-effective to do your black-and-white printing on your color printer as well. Best of all, HP supplies are designed to work precisely with your HP printer for optimal results and even let you know when supplies need to be replaced.
