For the HP LaserJet M9050DN MFP, HP 43X is the black toner cartridge and C9152A is the 110V maintenance kit. They are separate supplies, so the maintenance kit is not an alternative way to top up toner.
Toner Buzz carries genuine HP 43X toner along with the C9152A kit. Choose the cartridge when toner is running low, and keep the maintenance kit for its separate service job.
