Our take
The Samsung SCX-4729FW/XAA is a monochrome office MFP whose useful distinction is the combination of fax, automatic duplex, Ethernet and built-in Wi-Fi. HP's support crosswalk identifies the XAA part as SS177B, while the SCX-470x/472x guide covers the model family. Samsung lists print, copy, color scan and fax functions, plus a 250-sheet cassette and a single-sheet multipurpose feed. That is a practical document station for a small team, but the reviewed sources do not provide a comparable recommended monthly volume, and no source establishes the state of a particular used unit.
A small office that needs mono fax, copy and scan, automatic duplex and a choice of Wi-Fi or Ethernet..
Skip it if you need color printing, a current model, a verified recommended monthly range, or a larger paper supply without frequent loading.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Fax, copy, monochrome printing and color scanning cover several paper workflows without separate devices.
- Automatic duplex reduces the hand-turning step for recurring two-sided reports and forms.
- Built-in Ethernet and 802.11b/g/n wireless let a buyer choose a wired office connection or a wireless network.
What to weigh up
- The saved manufacturer material does not state a recommended monthly page range, so workload fit stays unknown.
- A 250-sheet main cassette plus one-sheet feed is modest beside the larger office machines in this catalog.
- The model is an older product, so parts, driver compatibility and the condition of a specific unit require checking.

What the features mean for you
Check the suffix before comparing listings
HP's support crosswalk maps SCX-4729FW/XAA to product code SS177B. Keep that identity with the model name when checking a unit because the SCX-4729 family also includes other suffixes and regional forms. The product guide supports the FW configuration, while the historical candidate clue is not an Amazon identity proof. Confirm the label and included power arrangement on the actual machine; this review describes the documented model, not the condition of a listing.
Use the four functions only if they solve real work
Samsung documents printing, copying, color scanning and fax in a monochrome laser MFP. That can consolidate incoming fax pages, copies and scanned color originals while keeping printed pages black and white. It is a closer fit to a paper-heavy home office than a print-only device, but a buyer who only produces occasional forms is accepting extra functions and a larger workflow than needed. The source does not make a current software-support promise, so check compatibility with the computers and fax line in use.
Automatic duplex helps on recurring paperwork
The manufacturer material identifies built-in two-sided printing, so the printer turns the sheet during a duplex job instead of requiring a manual refeed. That matters most for repeated multi-page reports, policies or handouts; it will not change the needs of one-page receipts. A 250-sheet cassette and one-sheet multipurpose feed mean envelopes or specialty stock can be loaded separately, but frequent multi-page work still requires realistic paper-loading expectations. No unsupported speed claim is needed to judge that trade-off.
Choose between wireless and wired setup
The SCX-4729FW adds 802.11b/g/n wireless networking and also lists 10/100 Ethernet and USB. That gives a small office more setup choices than a USB-only model. Wireless can avoid a cable run; Ethernet may be preferable where a stable wired connection is already available. Keep the two interfaces distinct when choosing a path, and verify that a used machine still joins the intended network. Wi-Fi availability does not establish compatibility with every current operating system or cloud-print service.
Treat the workload range as unknown
The reviewed exact-model material does not state a recommended monthly page range. A maximum duty-cycle number is not a routine target, so it should not be used to call this a heavy-workgroup printer. The matching profile leaves both recommended-volume endpoints null. If workload is a deciding factor, seek exact guidance from a current manufacturer record or consider a model with a published recommended band. For a used unit, ask about page count, service history, toner and drum status, and test the ADF and fax path before relying on it.
What else to compare
The Kyocera ECOSYS M3655idn is the larger wired fax MFP in this batch, with a much faster published engine and 600-sheet standard input but optional wireless. The Samsung is the smaller dual-network choice; its recommended volume remains unknown.
Before you buy
Does the SCX-4729FW print on both sides automatically?
Yes. Samsung documents built-in duplex printing for the SCX-4729FW family, so it can turn pages during a two-sided print job.
Can it connect over Wi-Fi as well as Ethernet?
Yes. The FW configuration documents 802.11b/g/n wireless alongside 10/100 Ethernet and USB connections.
What monthly workload does Samsung recommend?
The reviewed exact-model sources do not give a recommended monthly range. A maximum duty-cycle figure is not a substitute for that recommendation.
