Compatible toner for HP LaserJet fleets

This high-yield black cartridge replaces the HP 45A Q5945A and fits a wide range of LaserJet 4200, 4240, 4250, 4300, 4345 and 4350 series printers. It is built for offices that need reliable monochrome output without sourcing original supplies. The single-pack format keeps inventory simple for environments with standard print volumes.

Engineered for steady throughput

Materials comply with ISO 9001 and ISO 14001 standards, supporting consistent page quality across long print runs. The cartridge is rated at 20000 pages at five percent coverage on Letter or A4 media, matching the yield of the original unit. Installation follows the standard slot-in procedure with no special tools or firmware steps required.

Replaces OEM 45A in listed models

Buyers currently using genuine HP 45A cartridges in the compatible printers listed can switch to this unit for equivalent page count and print density. It is not suited for colour printing, for printers outside the 4200, 4240, 4250, 4300, 4345 or 4350 families, or for users who require manufacturer-branded supplies for warranty compliance.

Questions about this item

Does the 45A Q5945A toner cartridge produce noticeable heat or noise during continuous daily printing?

The cartridge is a toner supply unit with no moving parts of its own; heat and noise come from the LaserJet printer engine, not from the cartridge.

Must I already own a specific HP LaserJet model for this 45A Q5945A cartridge to work?

Yes — it fits HP LaserJet 4200, 4240, 4250, 4300, 4350 and 4345mfp series printers that accept the 45A Q5945A toner.

Will this 45A Q5945A cartridge work reliably in an older HP LaserJet 4200 that I still use?

The cartridge is engineered for full compatibility with the 4200 series and delivers the same 20000-page yield as the original HP 45A toner.
