The HP Color LaserJet Pro M454dw takes 414A standard-yield toner and 414X high-yield toner in black, cyan, magenta, and yellow. Black and color cartridges do not have to use the same capacity.
Toner Buzz carries genuine HP 414A and 414X toner as individual colors and complete sets. The mixed four-pack pairs high-yield black with standard-yield cyan, magenta, and yellow for a practical middle option between the two full sets.
