Great alternative
Great alternative to expensive toner cartridges. I recommend this for anyone with the HP. I buy more whenever I'm down to one.

Nice print quality
I'm a music minor so I'm printing loads of sheet music and previous toner always had trouble printing sheet music. This one was the first toner cartridge that actually printed well and I was really happy with the quality of printing. Thank you!

Superb quality
I have had excellent luck with this toner cartridges - It's works great. I have had my HP LaserJet 4240 for several years and have always used the HP toner cartridges. The black seems to always run out first so get an extra.

Very impressed!!
I don't see any difference with the quality of my printing. I was going to get rid of the printer since the cost of the actual HP replacement toner was so expensive. Now I'll keep the printer till it dies since the HP toner is so reasonably priced. Also t

Frequently Asked Questions
Our reorder sheet just says "42A". Is this that cartridge?
Yes. 42A is the short name for the Q5942A, and this listing is that cartridge in its plainest form: one black unit, $51.26, rated at 10,000 pages at 5% coverage. Purchasing departments order it by either code and receive the same box.
Which printers does the code cover?
The whole 4250 and 4350 family — the cartridge that feeds the LaserJet 4240 line's bigger siblings is one and the same unit across base, network, duplex and tray variants. A mixed fleet needs one line on the stock list, not five.
How should a first order be checked on arrival?
Against the label of the cartridge coming out of the printer. If the outgoing unit reads Q5942A or 42A, the incoming box matches; the swap itself takes a minute through the top cover.
Pages are fading on one edge. Replace or redistribute?
Redistribute first: out, a gentle side-to-side rock, back in. That restores even density when the cartridge is merely settled. If the fade is general rather than one-sided, the toner itself is nearly gone and replacement is the honest fix.
How far ahead should a single-printer office order?
At the first low-toner message. The warning leaves a working reserve, delivery from our warehouses is measured in days, and ordering on the warning means the new cartridge waits in its box rather than the printer waiting on the courier.
What terms protect the order?
A 1-year warranty and 1-year free returns, detailed on our shipping & returns page. We hold stock in warehouses in IL, PA, GA, and CA, and support answers Monday–Friday, 9 AM–5 PM CST.
About This Q5942A Single Cartridge
Some listings exist to be found by a model name; this one exists to be found by a code. It is the reference single in our HP range for anyone whose stock card, reorder sheet or asset register says Q5942A — no configuration choices, no variants to disambiguate.
That simplicity is the product: the standard-yield 42A, the family's common cartridge, priced as a routine line item and backed like one. Offices running several family members often standardise on this single for every machine they own.
