The original 201A Black toner cartridge has been precisely formulated by HP to deliver reliable and quality printing results. This is done by working harmoniously with HP paper and your HP printer. Over 50 Percent of the printing technology of your HP printer is contained within the cartridge itself, meaning every time you replace your cartridge you are installing a brand new print engine. This toner cartridge is compatible for use with the HP Colour LaserJet Pro M252/MFP M277 printer models. Using your HP cartridge alongside an HP printer results in the perfect balance of colour, permanence and reliability. The page yield is 1500 per cartridge. "Page yield" refers to an estimated yield reached by an industry-standard calculation. However, a number of other factors can affect page yield (e.g. printer, printer settings, types of pages printed and page content) so this number is not guaranteed and should be taken as a guide only. Once used HP products can be recycled with HP (see pack for instructions).
