LaserJet 4350DTNSL

The LaserJet 4350DTNSL completed HP's solutions lineup for the 4350 — the full-spec 2005 workgroup printer paired with enterprise management software. IT departments that ran standardized fleets knew this configuration well, and its supplies are the 4350 line's standard fare: the 42A cartridge in its standard Q5942A form, the high-yield Q5942X for longer intervals, and the Q5942AJ (42AJ) jumbo for the longest runs of all. Cartridges labeled with the family shorthand 42X are the high-yield tier of the same line.

A fleet standardized on one configuration wants one supply answer, and this page is built around that idea. Every listing below fits this printer; the only decision is how much toner you want in the box and how often you want to think about it. For a machine administered through central software, that decision is usually made once, at fleet level, and then simply repeated.

Which cartridge should you buy?

The jumbo Q5942AJ deserves first consideration here: it is a compatible cartridge that extends the 42X's already long intervals, which is exactly what a standardized fleet is optimizing for. The high-yield Q5942X remains the balanced default for a single busy unit, while the standard Q5942A covers quieter machines without overbuying. Multi-packs — up to five cartridges — keep a central store supplied across several machines, and MICR versions of the standard and high-yield cartridges are available on this page for any unit that also prints checks.

Chip, toner and everyday use

A printer watched by management software usually announces its hunger early: when the console flags a low cartridge, that is the moment to pull the spare, not when pages start to streak. Installing one is a door-open, slide-out, slide-in job — the chip on the new cartridge identifies it to the printer automatically. Store the fleet's spares sealed and flat, away from heat and humidity, and use the oldest first. Any yield figure quoted for these cartridges assumes about 5% coverage per page, so a department printing coverage-heavy forms should expect shorter cycles and plan its stock level accordingly.

Frequently Asked Questions

Which toner cartridge does the LaserJet 4350DTNSL use?

The Q5942A in standard form, or the Q5942X high-yield — with the Q5942AJ jumbo as the longest-running option. All three are interchangeable in the same slot.

What makes the Q5942AJ different from the Q5942X?

Capacity. The AJ is a jumbo-yield compatible filled beyond the high-yield 42X, so it prints more pages between changes. Fleets choose it to reduce service visits, not for any difference in fit or output.

Can this printer be shared across an office?

Yes — it connects by Ethernet, so one unit serves every workstation on the network once the driver is installed.

Prints are fading in the middle of a long run. What now?

The cartridge is nearing empty. Rock it gently side to side to redistribute the toner for a short reprieve, and install the spare as soon as the job allows.
