Pros & Considerations Based on Features
Pros:
Very compact size — suitable for small offices or home setups.
Good print speed (21 ppm) for a small mono laser
Multifunction: you can scan and copy, not just print.
Wireless printing + mobile printing makes it very flexible.
Energy saving with auto on/off.
Uses standard HP toner, so quality is good.
Considerations / Limitations
No duplex printing (i.e., no automatic double-sided print). ([HP][3])
Toner is mono only, so it’s not for color prints.
Small memory (64 MB) — enough for lighter tasks, but may struggle with very large jobs.
Dynamic security: may not accept non-HP toner chips. ([HP][3])
Recommended monthly volume is relatively modest (100–1000 pages), so may not be ideal for very high-volume printing.
Summary
The HP LaserJet M140w is a compact, efficient, black-and-white laser multifunction printer aimed at home users or small offices. It handles essential tasks — printing, scanning, copying — with decent speed, wireless connectivity, and a small footprint. It’s especially good if you need reliable text printing and occasional scanning, without a large or color printing budget.
