Our take
The HP LaserJet Pro M402n is a monochrome print-only printer with a clear wired office role. HP rates it up to 40 pages per minute, lists Gigabit Ethernet and USB, and recommends a monthly volume of 750 to 4,000 pages. The exact n suffix is important because other M402 variants have different options. The saved U.S. support page does not establish the duplex mode for this exact model, so automatic and manual duplex remain unknown in the matching profile. This can suit a shared black-document queue when the workload range fits, but buyers who require two-sided printing should verify the model before relying on it.
A wired office that wants a quick monochrome print-only queue and can verify duplex and current software requirements..
It is not for color, copy or scan work, fax, wireless-only networks, or an automatic-duplex requirement that cannot be verified on the exact model.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HP specifies up to 40 ppm output and a 750–4,000 page recommended monthly volume.
- Gigabit Ethernet and USB provide a documented wired network and direct connection choice.
- The print-only configuration avoids paying for scanner or fax functions that a team does not need.
What to weigh up
- Duplex mode remains unknown in the reviewed exact M402n support record.
- Built-in Wi-Fi is not listed for the exact n model.
- The old model's current driver support, supplies and a particular unit's condition require separate checks.

What the features mean for you
A no-frills monochrome print queue
HP identifies the M402n as a printer rather than an all-in-one. It is intended for black documents, not color output or copy, scan and fax tasks. That narrow role is useful in an office that already has shared scanners or MFPs and wants a separate printer for recurring text pages. The product code and full n suffix should be checked because the M402 family includes related configurations. Do not assume that a listing for M402 includes the n model's ports or another variant's duplex behavior without seeing the exact label.
Rated output speed and workload guidance
HP rates the M402n up to 40 pages per minute and recommends 750 to 4,000 pages each month. These are different measures: ppm is a model speed rating, while the recommended range helps evaluate expected routine use. Neither describes how fast an aging individual machine will operate or how much life remains. Compare the office's ordinary month to the recommendation, and treat the upper duty cycle only as a separate maximum. Ask for a sample print, page count and service history if considering a used unit, since HP's product page cannot reveal its maintenance state.
Ethernet is the standard sharing route
HP lists Gigabit Ethernet and USB for the exact M402n. Ethernet can connect the printer to an office network, while USB supports a nearby workstation. Wireless capability is not listed, so the source does not support a built-in Wi-Fi claim. A team with a wireless-only setup should either verify another supported network arrangement or select a model with confirmed Wi-Fi. Before purchase, check the device's physical ports, intended network security and compatible drivers; model-level Ethernet does not prove that a particular used port still functions.
Do not assume duplex from the family name
The M402 family includes models with different suffixes, but the saved exact M402n U.S. page does not resolve manual or automatic duplex. For that reason both capabilities remain unknown rather than borrowed from the M402dn or M402dne. A buyer who prints one-sided pages may not care, but someone with a hard automatic-duplex requirement should get a primary specification or verify the physical model and its operation first. If duplex affects the choice, the Lexmark MS415dn is an alternative with automatic duplex clearly listed for its exact part.
A paper and connection choice for shared use
HP's exact M402n record lists a 100-sheet multipurpose tray alongside a 250-sheet main tray, giving 350 sheets of standard input. This supports ordinary office stock and a separate feed for special media. It is not an especially large input configuration compared with enterprise machines, so longer queues may need more frequent attention. Optional paper drawers should not be presumed included. Ask the seller to identify which trays accompany the printer and test each feed path if paper capacity is part of the reason to choose the model.
Check lifecycle details before relying on a legacy printer
The official support page confirms stable model-level features but not the present condition of a marketplace machine. Verify its exact M402n label, network port, print sample, tray operation, included cartridge, page count if supplied and return terms. Check whether current computers can use the driver path that your office requires and whether the maker's supply information remains useful for your purchasing channel. This review makes no claim about current stock, price or the historical ASIN. The tagged search uses the exact model name so each buyer can compare the actual offer and its configuration.
What else to compare
The Lexmark MS415dn documents standard automatic duplex and Gigabit Ethernet; the HP P3015n is another wired mono printer with a higher 42-ppm rating.
