Our take
The M125nw is a monochrome print, copy and scan device whose reviewed U.S. specifications list up to 21 pages per minute, manual duplex and a 250–2,000-page recommended monthly range. It uses a flatbed rather than a documented ADF and does not list fax. Its main buying complication is connectivity: HP's U.S. model specification and a separate product-number table disagree about Wi-Fi and Ethernet. That uncertainty should remain visible until a buyer can verify the actual unit and part.
A small office that can accept manual page handling and will verify the exact ports before purchase..
Avoid it if built-in Wi-Fi, Ethernet, automatic duplex, fax or feeder-based scanning is a hard requirement that must be matched from the current evidence.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HP documents monochrome print, copy and scan with a 250–2,000-page monthly recommendation.
- Manual duplex is listed, so two-sided output is possible with a person handling the pages.
- The CZ173A clue is mapped by HP to the M125nw model.
What to weigh up
- HP's U.S. specification and another HP connectivity table conflict on Wi-Fi and Ethernet.
- Automatic duplex, fax and an ADF are not listed in the reviewed U.S. specification.
- Manual duplex adds handling time to two-sided jobs compared with an automatic duplexer.

What the features mean for you
Copy and scan stay simple with a flatbed
HP lists print, copy and scan for the M125nw, with no fax function or ADF established in the reviewed U.S. specification. A flatbed approach can work for a book page, a signed sheet or occasional originals, but it means placing pages individually rather than feeding a stack. That is a meaningful difference for a small office that scans forms every day. Buyers who need a feeder or telephone fax should select a model whose exact source confirms those functions rather than relying on the M125 series name.
Manual duplex is a different everyday workflow
HP specifies manual duplex printing for this model. That allows two-sided output through a process that requires the user or driver to handle sheets between passes; it is not equivalent to automatic page turning. For a few double-sided pages each week, that may be acceptable. For recurring packets, the repeated step can become a nuisance and a source of ordering mistakes. The profile therefore records automatic duplex as false and manual duplex as supported, instead of scoring the model as an automatic-duplex match.
Use the monthly recommendation, not only the speed
HP rates output up to 21 pages per minute and recommends 250 to 2,000 pages each month. The recommended range is a practical guide to workload fit; it is more useful for planning than a maximum duty-cycle ceiling. A small office with regular forms and reports may fit within the range, while a larger team should compare a higher-capacity workgroup model. Speed ratings describe the manufacturer's conditions, not a measured promise for mixed jobs or an older unit with unknown maintenance history.
The exact connection evidence conflicts
HP maps the candidate clue CZ173A to the M125nw, but its U.S. product specification lists USB-only standard connectivity while another HP product-number connectivity table lists Wi-Fi and Ethernet for the same model code. This is a source conflict, not a reason to choose whichever feature sounds more useful. The matching profile leaves both Wi-Fi and Ethernet unknown. Before relying on a shared network setup, inspect the actual rear ports and label and find documentation tied to the exact unit's regional part.
Shortlist it only when the unresolved ports are tolerable
The M125nw can suit monochrome copy/scan work with a flatbed, manual two-sided output and a modest monthly routine. It is less suitable when a shared wireless setup or hands-off duplexing is essential. Check the exact model and part, condition of the scan glass and paper path, driver availability and supplies before purchase. The available manufacturer evidence helps identify the product, but it cannot settle a seller's particular configuration or show that its interfaces work. Use the model search to compare exact suffixes carefully.
What else to compare
Compare a confirmed wireless mono MFP for shared network use, or an automatic-duplex model when two-sided output is frequent.
Before you buy
Does the M125nw have fax?
HP's reviewed U.S. specification lists print, copy and scan; it does not list fax for the M125nw.
Does it print both sides automatically?
No. The U.S. source lists manual duplex, which involves a handling step rather than automatic page turning.
Can I rely on Wi-Fi or Ethernet?
The HP source set conflicts on these ports, so verify the actual CZ173A unit before treating either connection as available.

The decision
The M125nw offers a modest monochrome flatbed MFP workflow with manual duplex. Its port conflict is material, so select it only when connectivity can be checked on the exact unit.
