Genuine OEM HP LaserJet 4345xs mfp Toners

HP 45A black toner, part Q5945A, is the cartridge used by the LaserJet 4345xs MFP. The Q5997A and Q5998A kits handle maintenance instead of printing supplies.

Toner Buzz carries genuine HP 45A and the two maintenance-kit choices. Start with the printer message: toner points to 45A, while a maintenance request should be matched to the exact kit number.
