Our take
The HP LaserJet Pro 400 M401n is a monochrome print-only model with a published 750–3,000 page recommended monthly volume and a maximum black speed of 35 ppm. HP explicitly lists wireless capability as no. Those facts give it a defined office-oriented role, but this review keeps duplex and exact wired connectivity unconfirmed because the saved evidence does not settle them for the n variant.

Do not choose it if Wi-Fi is a requirement, if you need a copier or scanner, or if automatic duplex must be present without checking the exact unit documentation.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HP identifies the M401n variant and lists monochrome printing up to 35 ppm.
- A 750–3,000 page recommended monthly volume is documented for the model.
- The official source explicitly states that built-in wireless capability is not available.
What to weigh up
- The exact M401n's duplex configuration is unresolved in the evidence used for this batch.
- Wireless printing is not available according to HP's product specification.
- Its age means current condition, toner access, and compatible driver support require a buyer-side check.

What the features mean for you
A defined monochrome workload
HP identifies the M401n as a one-cartridge black printer and rates it up to 35 pages per minute. The recommended monthly volume is 750 to 3,000 pages. That helps place it between a very light personal printer and a high-volume workgroup engine. It is a useful distinction for buyers who print routine forms, policies, or internal drafts, but it does not mean each user will see 35 pages every minute. HP notes that speed varies with system configuration, software, and document complexity.
The n variant should be checked on the label
The candidate history contains several related M401 suffixes, so this recommendation is tied specifically to M401n. HP's product page confirms the model name and separately states no wireless capability. Because the letters identify configurations in a product family, do not accept an M401dw or M401dne as an equivalent substitute when comparing duplex or network behavior. Check the exact label on a seller's item and match it to the product documentation before purchasing. This keeps family-level specifications from being mistakenly attributed to the n configuration.
Wireless is a firm mismatch
HP lists wireless capability as no. If the printer must connect directly to a home or small-office Wi-Fi network, the M401n does not meet that requirement as documented. Some workplaces may share a printer through a wired host or a separate print server, but that is a different setup and has not been validated for the buyer's equipment. We should not convert a possible external workaround into a built-in product feature. In the finder, wireless remains a clear must-have that this exact model cannot satisfy.
Leave duplex and ports open until proven
The M401n packet intentionally leaves duplex and exact connection details unresolved for this precise SKU. The family contains variants whose names and feature sets are similar, so inferring automatic duplex from a sibling product would be unsafe. Before comparing a used device with models that document automatic page turning, locate the manual or configuration sheet for the M401n label itself. The same care applies to Ethernet: a model suffix or old marketplace title is not enough to establish the ports on a unit, and an unknown fact should not be treated as a match.
Ownership is about the actual unit, not a headline spec
The HP support page establishes core print specifications but cannot tell us whether an offered unit has a worn feed path, a clean fuser, original or compatible toner, or a valid return option. It also does not establish current prices or supply conditions. Buyers considering a legacy printer should ask for a clear model label and actual working state, check what cartridge is included, and verify that the operating systems in use can obtain a suitable driver. Those details make the difference between a sensible reuse purchase and an avoidable maintenance project.
A cautious fit within this shortlist
Among the products in this first batch, the HP P3005d is also monochrome and prints automatically on both sides according to its documentation, while the Lexmark MS810de targets a higher recommended volume and includes Ethernet. The M401n's lower 750–3,000 page recommendation may suit a smaller work queue, but its unknown duplex and port details keep it behind models with confirmed network and paper handling. Choose it only after the exact configuration is documented; if you need predictable duplex or Wi-Fi, select a model whose official source answers that question directly.
What else to compare
The HP P3005d has documented automatic duplex and a 1,500–5,000 page recommendation. Lexmark's MS810de includes Ethernet and a much higher recommended-volume range, but it is discontinued.
Before you buy
Does the M401n have Wi-Fi?
No. HP's specifications for the exact M401n state that wireless capability is not available.
Does it print both sides automatically?
The evidence in this guide does not confirm duplex for the M401n variant. Check the exact model documentation before relying on that feature.
How many pages per month does HP recommend?
HP gives a recommended range of 750 to 3,000 pages per month; this is distinct from the printer's maximum duty-cycle figure.

The decision
The M401n is worth a look for monochrome office printing only when its no-wireless limit suits the setup and the exact duplex and wired ports are checked. Use those confirmed details, not sibling-model assumptions, to make the final decision.
