Genuine OEM HP LaserJet 4250tn Toners

The HP LaserJet 4250tn uses HP 42A black toner or high-yield HP 42X. Its Q5421A maintenance kit is a separate service item, so the printer's message matters before you order.

Toner Buzz carries genuine HP 42A and 42X cartridges, a two-pack of 42X, and the maintenance kit. Pick toner for a cartridge message and the kit only when maintenance is identified.
