Our take
HP identifies the LaserJet Pro 4001n as a black-only print device, product number 2Z599F. HP rates it up to 42 ppm on Letter and recommends 750–4,000 pages per month. The n configuration has Gigabit Ethernet and USB, but HP's model comparison says automatic duplex and built-in wireless are unavailable on this version. Tray 1 holds 100 sheets and Tray 2 holds 250. It suits a wired workflow that prioritizes speed over automatic two-sided printing.
A wired office or desk that values fast black-only output and can accept one-sided or manually handled two-sided jobs..
Choose a 4001dn, a wireless model, or another printer if automatic duplex, built-in Wi-Fi, color, or copy and scan functions are required.

Full review: how the features affect your choice
What the features mean for you
What does the 4001n do well?
HP documents a print-only monochrome laser printer rated up to 42 pages per minute on Letter paper. The speed and black-only design suit a desk or team that produces frequent text documents without needing color, copy, scan, or fax functions. HP notes that exact speed can vary with system setup and document complexity, so treat the figure as a rated comparison. It is not a measured result from an individual device or a promise for every print job.
What does the n suffix mean for connections?
HP lists 10/100/1000 Ethernet and Hi-Speed USB 2.0 for the 4001n. Those choices allow a direct computer connection or a wired shared network. The n configuration does not include the built-in wireless features HP assigns to dw models. A buyer should check the product number and suffix, since the 4001 series includes nearby versions with different paper handling and networking. Do not infer wireless from a broad family listing.
Can it print two-sided automatically?
HP's model table says automatic duplex is not available on the 4001n; the dn and dw versions add that capability. The n can still be used for one-sided pages, but a two-sided workflow requires manual paper handling or another documented setup. This distinction matters for recurring reports and jobs where the user does not want to monitor a second pass. If automatic duplex is a must-have, choose a version that HP explicitly lists with it.
Does the recommended volume fit your queue?
HP recommends 750–4,000 pages per month. Compare that range with an ordinary month, not a maximum duty-cycle number or a short peak. The lower endpoint can help a team distinguish occasional use from a regular shared queue; the upper endpoint is not a guarantee that every job will run at rated speed. A larger deployment may need an enterprise model with a higher published recommendation and optional paper capacity.
How much paper can it keep ready?
HP's user guide lists a 100-sheet Tray 1 and a 250-sheet Tray 2, with an optional additional tray available for the series. The standard 350-sheet supply fits a small team better than a high-volume office that wants long intervals between refills. Confirm whether an optional tray is actually included in a listing; the basic 4001n configuration does not automatically include every accessory mentioned in family documentation. HP separately recommends a 750–4,000 page monthly range, which is a better workload guide than tray capacity alone.
What should buyers check on a particular unit?
The HP sources establish the original 4001n features, not the health of an individual printer. Confirm the label says 4001n and product number 2Z599F, test Ethernet and USB, inspect the paper path, and ask about service and return terms. Check that manual duplex is acceptable for your documents. No current offer, price, or stock status is represented here; those details have to be checked on the specific listing being considered.
