Our take
The HP LaserJet Pro M402dn is a monochrome print-only model aimed at a wired desk or small workgroup. HP rates it up to 40 pages per minute on Letter paper and lists automatic duplex, two standard paper trays, built-in Ethernet and a 750–4,000 page recommended monthly range. It does not copy, scan or fax, and its U.S. product page marks it discontinued. The M402 family has neighboring suffixes with different networking, so use the exact M402dn and C5F94A#BGJ identifiers when checking any listing. The specifications describe the model rather than the age, toner or condition of a used unit.
A wired office needing brisk black text and automatic two-sided printing without copy or scan functions..
Look elsewhere if color printing, wireless networking, document capture, faxing or a currently supported model is required.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HP lists up to 40 ppm Letter output for the exact M402dn configuration.
- Automatic duplex is standard, so a two-sided job does not need manual page turning.
- The 750–4,000 page recommended range gives a workload reference for a small office.
What to weigh up
- This printer only prints in monochrome and has no copy, scan or fax functions.
- Built-in Ethernet is documented but built-in Wi-Fi is not; the model is wired-first.
- HP marks the product discontinued, and an old specification cannot guarantee current drivers, supplies or a particular unit's condition.

What the features mean for you
A focused black-and-white print queue
HP identifies the M402dn as a print-only monochrome laser printer. That narrow feature set makes sense when the office already has a copier or scanner and wants a separate output device for forms, invoices or text-heavy documents. It cannot digitize originals or send faxes. HP rates black output up to 40 pages per minute on Letter paper; the rated speed is a model comparison, not a promise for every page layout or a machine with unknown wear. Check the suffix carefully because the M402 family includes other configurations whose networking differs.
Automatic duplex helps with recurring packets
The exact HP product page lists automatic duplex printing as standard. The printer turns pages for two-sided jobs, reducing hand handling when producing policies, manuals or meeting packets. HP advertises two-sided output at up to 32 images per minute, a separate measurement from the one-sided page-per-minute rating. Duplex is useful only if the office needs it; if all jobs are short single-sided notes, this feature may not change the workflow much. For a used unit, check both sides of a sample sheet and verify that paper feeds without skew or repeated jams.
Use the monthly range to size the workload
HP recommends 750 to 4,000 pages per month. That range gives a practical way to compare it with printers aimed at occasional home printing or higher-volume departments. It is not the same as the stated maximum duty cycle, and it does not forecast the service life of an individual unit. The 40 ppm speed rating also does not mean that sustained high volume is automatically appropriate. Consider actual monthly jobs, refill frequency and maintenance history together, especially when evaluating a printer that has been out of production.
Two trays and network access support shared use
The M402dn has two standard paper trays and built-in Ethernet. HP describes a maximum input capacity of up to 900 sheets when optional handling is added, so the extra capacity should not be assumed in a listing. Ethernet supports a wired shared queue, while USB offers a direct connection. HP's exact M402dn configuration does not list built-in wireless. Before purchasing, ask which trays are actually present and check that the network and USB ports work; a family description for M402dw or M402n should not be used to fill gaps in this model's listing.
Treat discontinuation and seller condition separately
HP labels the M402dn discontinued. The product specification still helps identify its standard functions, but it cannot establish present stock, the age of an offered printer, toner remaining, roller condition or the return policy. Confirm a label photo showing C5F94A#BGJ, ask whether the optional third tray is included and test duplex, Ethernet and USB if buying used. A tagged Amazon search is only a way to locate model-specific offers; it does not verify that each result is the exact part or in good condition. Confirm the cartridge region before ordering supplies.
What else to compare
Compare the HP M402dw if built-in wireless is essential; verify its exact suffix and part because network features differ across the M402 family.
