The HP Color LaserJet Pro M454dn uses HP 414A and 414X toner in black, cyan, magenta, and yellow. Both lines cover the same color positions, with 414X providing the higher-capacity choice when you print more often.
Toner Buzz carries genuine HP 414A and 414X toner as individual colors and complete sets, plus a mixed set pairing 414X black with 414A colors. Choose one cartridge for a single alert or the set that matches the capacities you need.
