Our take
HP's U.S. product page maps the M401dw to product CF285A and identifies it as a monochrome print-only laser printer. It is rated up to 35 ppm Letter, includes an automatic duplexer, and has built-in 802.11b/g/n wireless plus Gigabit Ethernet and USB. Standard input totals 300 sheets across the 250-sheet tray and 50-sheet multipurpose feed. HP recommends a monthly page volume of 750 to 3,000, which is more useful for workload planning than the 50,000-page maximum duty figure. The M401dw is discontinued, so check the exact suffix, current driver compatibility, and machine condition before choosing a specific used unit.
A home or small office that needs black-only pages, wireless or Ethernet sharing, automatic two-sided output, and a documented modest monthly range..
It is not a color or multifunction device, and its legacy status may not suit buyers who need current manufacturer sales support or a guaranteed driver path for new systems.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HP rates monochrome Letter output up to 35 ppm and maps the exact M401dw to product CF285A.
- The standard automatic duplexer reduces manual handling for recurring two-sided documents.
- Built-in Wi-Fi and Gigabit Ethernet plus a 750–3,000 page recommendation support a clearly defined shared-office role.
What to weigh up
- The M401dw is discontinued and requires a seller-specific condition and driver check.
- It is print-only and black-only; copy, scan, fax, or color work needs another device.
- The exact suffix matters because M401 family variants do not all include the same interfaces and duplex equipment.

What the features mean for you
Verify the dw configuration
HP's U.S. record identifies the M401dw as product CF285A and lists the `dw` model as a wireless, automatic-duplex configuration. That exact mapping is useful because the M401 family also includes variants whose network and duplex packages differ. Before buying a used machine, compare its product label with CF285A rather than relying on a generic M401 title. The exact page describes printing only, so do not expect scanning or copying just because a marketplace description calls it an all-in-one. Product identity sets the boundaries for every other fact in this review.
Rated speed for recurring black documents
HP rates the M401dw at up to 35 pages per minute on Letter paper. This can be a useful speed class for a compact office queue that prints reports, forms, and text-heavy packets, while real jobs vary with page coverage, host, and settings. The page also lists 300 sheets of standard paper input: a 250-sheet main tray plus a 50-sheet multipurpose tray. Those specs help estimate the device's role, but they do not promise a particular page-per-minute result in a specific setup or tell us whether a secondhand feed path remains in good condition.
Automatic duplex saves a handling step
The M401dw includes a standard automatic duplexer. The printer can turn paper to print the second side without a user standing by to reinsert each sheet. That makes it more convenient for multipage documents than a model whose two-sided output depends on manual reloading. Duplex is a print feature here; it does not create scan, copy, or fax capabilities. For an older unit, ask the seller to demonstrate both sides of a short document and check for alignment or feed errors. HP's source proves the intended configuration, not the present state of an individual duplex assembly.
Choose Wi-Fi or Ethernet for sharing
HP lists built-in wireless 802.11b/g/n and Gigabit Ethernet, as well as USB. Wi-Fi helps place the printer where a cable would be inconvenient, while Ethernet supports a fixed office queue with a physical network connection. USB is available for local attachment. These interfaces are standard on the exact M401dw and should not be transferred to the M401n or other family members. A buyer should check that the old wireless security options and available drivers fit the current network. A verified connection interface does not guarantee compatibility with every operating system or managed office setup.
Use HP's recommended volume, not the duty cycle
HP recommends 750 to 3,000 pages per month for this model. Its separate maximum duty cycle is 50,000 pages, a durability comparison rather than a routine workload target. The recommendation can help a small office compare machines by likely monthly use without guessing from speed or tray size. If the workload is consistently outside this interval, look for a model whose published guidance fits better. The M401dw can satisfy a monochrome wireless duplex need, but it cannot add color or MFP functions. A discontinued product also makes supply availability and driver support important questions before purchasing a particular unit.
What else to compare
The Xerox Phaser 3260DI is another mono wireless duplex printer, rated up to 29 ppm Letter, with USB-only connectivity and no recommended monthly range in the reviewed Xerox source. Choose it when its compact wireless placement is enough; choose a fax-capable MFP when paper intake matters.
Before you buy
Does the M401dw include automatic two-sided printing?
Yes. HP lists a standard automatic duplexer for the exact M401dw configuration.
What monthly range does HP recommend?
HP recommends 750 to 3,000 printed pages per month for the M401dw; the 50,000-page duty cycle is a different maximum.
Does the M401dw scan or copy?
No. HP lists its function as print only; choose an MFP if scanning or copying is part of the workflow.
