Colour LaserJet printers require a full set of four toner colours - cyan, magenta, yellow, and black - to produce colour output, and this listing covers the yellow cartridge specifically; a business or office running one of the M254/M280/M281-series colour LaserJet printers would typically need to keep all four 203-series colours in stock (or on reorder) rather than yellow alone. Using the genuine HP 203A cartridge rather than a compatible/generic equivalent ensures HP's stated colour accuracy and page-yield figures, and avoids any cartridge-authentication issues some HP printer firmware can raise with non-genuine consumables. As a standard-capacity (not high-yield) cartridge, it suits lighter colour-printing volumes - offices printing colour only occasionally alongside a much higher volume of black-and-white output, which is the typical usage pattern this printer class is designed around, rather than a dedicated colour-heavy print shop that would be better served by a higher-yield cartridge tier or a different printer class entirely.
