These cartridges stand up to a steady diet of 1200 dpi at 12, 16, 18, or 24 ppm without missing a dot. They print on everything from bond paper and card stock to transparencies and labels. Gray scale transitions are super smooth to ensure the best possible print quality.¤¤Lexmark Return Program Cartridges are sold at a discount versus the prices of regular cartridges in exchange for the customer's agreement to use the cartridge only once and return it only to Lexmark for remanufacturing or recycling.
