Aster Graphics Inc 45A Q5945A Black Toner Cartridge 2 Pack

What this pack contains

This pack supplies two black toner cartridges built to replace the HP 45A Q5945A. Each unit is rated for approximately 20000 pages at standard letter or A4 coverage. The cartridges are manufactured from materials compliant with ISO 9001 and ISO 14001 standards. They are intended for offices and workgroups that run high-volume monochrome printing on compatible HP LaserJet hardware.

Printer models to verify

Before ordering, confirm that your printer appears in the supported list covering the HP LaserJet 4200, 4240, 4250, 4300, 4345 and 4350 series including network, duplex and MFP variants. Check the current cartridge label on your device to ensure it reads 45A or Q5945A. The cartridges are designed for straightforward installation with instructions included, but they will not function in printers outside the named series.

Who this suits and who it does not

This two-pack suits buyers who want a high-yield black toner supply for the listed HP LaserJet models and prefer a compatible alternative to the original brand. It is not for users who need colour output, who operate printers outside the 4200, 4240, 4250, 4300, 4345 or 4350 families, or who require a single cartridge rather than a twin pack.
