Questions about this item

Should I choose the 42X high-yield or the 42A standard cartridge?

The 42X yields approximately 20000 pages, while the 42A replacement model offers a lower yield; choose 42X for higher volume printing on LaserJet 4240, 4250 or 4350 series.

What does the 20000-page yield mean for daily office use?

At five percent coverage the cartridge prints roughly 20000 pages; actual output varies with page density, duplex settings and environmental conditions such as 10 to 80% RH operating humidity.

Which printer models accept the Q5942X and does the cartridge interface limit performance?

The cartridge fits HP LaserJet 4240, 4250 and 4350 series; it uses the native LaserJet interface so print speed and quality are governed by the printer engine, not the cartridge.
