HP M140w: a small monochrome printer with color flatbed capture review

Small black-and-white jobs with a flatbed beside them

The HP LaserJet M140w is a monochrome printer, copier and color-capable flatbed scanner for a small desk. Its useful routine is straightforward: load ordinary paper, print short documents, and place individual originals on the glass when a copy or electronic file is needed. There is no original feeder, automatic print duplexer, Ethernet socket or hardware fax.

This review covers the exact US 7MD72F#BGJ configuration, with its documented 110–127-V, 50–60-Hz supply. The surviving US reference does not show an exact discontinued notice, but that does not establish stock. The separately reviewed M140we is a different edition; its e-model setup and lifetime conditions are not transferred to this M140w.

Published Letter output is up to 21 ppm. HP recommends 100–1,000 printed pages monthly, separate from the 8,000-page maximum duty figure. These are manufacturer declarations, not measured review results. The guide also explains that printing can pause during cooling under some operating conditions and resumes when the engine is ready.

Choose USB or the actual 2.4-GHz network

Included connections are a USB 2.0 device interface and 802.11b/g/n Wi-Fi at 2.4 GHz. Bluetooth Low Energy appears in setup material, but the manual explicitly says Bluetooth assists setup and does not carry print jobs. No 5-GHz radio or Ethernet option is counted.

The documented computer setup connects USB or joins the office wireless network, adds the actual printer in the HP application and follows its prompts. The manual uses the older HP Smart name; current product material calls it the HP app. Its full functionality requires an HP account and Internet access, and the setup routine asks for account registration when prompted. Verify the exact application and OS combination before relying on scanning features.

A compatible router can also establish wireless connectivity through WPS. Press its WPS button, then hold the printer's Wireless button for five seconds within two minutes. A steady wireless light confirms connection. For application setup, Bluetooth and location permissions may be requested on the phone; those permissions do not make this a Bluetooth printer.

Glass size limits the originals you can digitize

The flatbed reaches 216 × 297 mm, approximately 8.5 × 11.7 inches, covering Letter and A4. Independently documented color scanning reaches up to 600 ppi. Put the original face down against the rear-left alignment mark and close the lid. A Legal page can be printed on suitable input stock, but it does not fit this glass as a full-size scan.

With compatible computer software, HP Smart can use the printer scanner and save images locally or share them through applications. The guide separately documents HP Scan through Printer Assistant on Windows 7, and HP Easy Scan on macOS, where File and Save stores collected scans. These historical procedures establish distinct supported software arrangements, not a blanket guarantee for every present OS.

Choose the printer's scanner when a faithful original capture is intended. The application's camera capture is a separate workflow. Sharing a scan through email or cloud storage is also an application operation; it does not establish a printer-side SMTP server setup or a standalone fax line.

There is no feeder to process a stack, and no automatic or single-pass two-sided scanning. ID Copy instead captures one card side, prompts for the other side on the same glass section, and places both images on one printed sheet. The user turns the card.

One input and a manual second pass

The single input is specified for up to 150 ordinary sheets, with a separate 100-sheet output. Letter, Legal and A4 are supported printing sizes. Ordinary media weight is listed as 65–120 g/m²; do not apply the sheet count unchanged to every envelope or heavier material. A3 and 11 × 17-inch Tabloid are outside this path.

Remove existing media, load sound plain stock face up with the top forward, bring the guides to its edges and extend the output support. Do not fan the stack or add and remove sheets while printing. For labels, place the sheet centrally, printable face up with its top toward the back, then adjust the guides.

Envelopes use the same input, up to ten where the size is supported. Follow the manual's flap-dependent orientation: a short-edge flap faces up with the opposite short edge entering, while a long-edge flap faces down with the short postage end toward the printer. Set the actual size and type rather than assuming plain-paper settings.

Two-sided printing is manual. In the Windows Layout controls, select Print on Both Sides Manually. After the first pass, remove blank stock and return the output printed face down, top edge first, then confirm at the computer and press Start Copy/Resume if prompted. The Mac manual-duplex route similarly needs an installed HP driver and may be unavailable through AirPrint.

Direct printing has its own connection conditions

AirPrint and Mopria certification are expressly listed. For normal mobile printing, put the device and printer on the same Wi-Fi network. The original guide also explicitly permits AirPrint using Wi-Fi Direct: enable Direct, join the printer's signal and provide its password or requested confirmation. Some phones must reconnect to the office network afterward.

Those mobile print plans do not inherit confirmed desktop paper controls, scanning, input capacity or duplex behavior. The Wi-Fi Direct pairing PIN and web-server administration password are not proof of PIN-held document release.

Keep supply and setup promises specific

The US brochure declares approximately 300 pages for the supplied cartridge and approximately 950 pages for replacement 141A W1410A, using the stated ISO/IEC 19752 continuous-printing basis. Neither figure measures toner remaining in a particular unit. Dynamic security concerns the cartridge's HP chip and can block non-HP chips after updates; it does not by itself establish an HP+ lifetime agreement.

The US brochure says to purchase USB cable separately. It lists a 14.2 × 10.4 × 7.8-inch body and 11.86 lb, without a stated cartridge-weight basis. Maximum dimensions grow to 16.8 inches deep and 13.7 inches high. Allow for the open glass lid, paper supports, cable and maintenance access when fitting it into the desk.
