The Lexmark High Resolution Standard Yield Black Print Cartridge provides outstanding print quality making images and text look incredibly sharp and crisp, even on plain paper!¤¤All Lexmark inkjet cartridges have the actual print head, there where the core inkjet technology lies, integrated to the cartridge bottle. The main advantage to having the print head as an integrated part to the cartridge is that Lexmark customers get a new print head with each cartridge replacement! This is each time like getting a brand new printer all over again! No risk of deterioration of the print head (and therefore a decrease in quality) during the life of the printer as can be the case with other manufacturers who integrate the print head as a fixed part inside the printer itself.¤¤Lexmark was the first manufacturer to introduce 1200x1200 dpi print heads. 1200x1200 dots per inch is the ability that Lexmark print heads have to place individual droplets of ink accurately on a 1200x1200 matrix per square inch of paper. Extreme precision and high resolution lead to the first class print quality provided by Lexmark printheads. With the introduction of the Z52 Color Jetprinter that can achieve a resolution of 2400x1200 dpi, Lexmark provides the ultimate in high resolution printing today!¤¤Lexmark uses pigment-based inks for the development of all their black inks. The reason for this is simple as pigmented inks are extremely resistant to fading over time, they are waterproof and even infra-red readable! The Lexmark pigmented black ink ensures maximum performance in black text print quality. The result is incredibly sharp, crisp, laser-quality images and text, even on plain paper!¤¤All Lexmark printer drivers offer a choice of printing modes based on the quality required and the time available to customers. The Quick Print mode (600x300 dpi) uses approximately only 50% of the ink quantity used in higher printing modes and provides a maximum print speed while still ensuring a more than acceptable quality. The Quick Print mode enables you to use the ink in an economical and efficient way based on your specific needs!
