Your needs, this model
Does it fit your priorities?
Can Wi-Fi computer printing combine Legal duplex, PIN release, 350 sheets and 7,000 monthly pages?
Yes with earlier references enabled, the proper active wireless setup and compatible protected-job software. Exact configuration and original paper/PIN routines support it.
Explore this need in the finder →Can a suitable shared network provide both documented AirPrint and Mopria printing?
Yes for compatible devices and firmware. Exact protocol support is listed; shared networking must make the printer reachable.
Explore this need in the finder →Can generic cloud-scan marketing satisfy scanning and copying paper originals?
No. Official hardware classification is print only, black and white; mobile-device capture and software do not create a document scanner.

The Lexmark B3442dw is an earlier monochrome printer with automatic duplex, built-in Wi-Fi and 350 sheets of combined input. Exact US part 29S0300 includes a two-line LCD, USB Type-B and 10/100BaseTX Ethernet. Its recommended monthly range is 800–8,000 pages, with exact B34 replacement toner options reaching 6,000 declared pages.
Lexmark marks the model discontinued. Check the offered unit, regional supplies, installed accessories and usable software. Similar dimensions and a common guide do not make it an MS431 with that model's larger 55B toner range. Correct supply identity is a practical part of comparing ownership arrangements.
Specific hardware records resolve broad marketing language
The official classification is print-only black and white. The exact specification identifies a two-line LCD and says Touch Screen Display No. Generic references to saving scans to cloud services describe software or documents captured elsewhere; they do not establish a physical document scanner inside this printer.
Likewise, marketing mentions two optional input trays, while the detailed configuration lists a 550-sheet option and 900-sheet maximum. The concrete supplied arrangement remains 250 plus 100 sheets. Confirm actual supported accessories before planning expansion, rather than using a broad paragraph to construct a different paper system.
Choose an actual active connection arrangement
Standard 802.11b/g/n wireless, Ethernet and USB Type-B provide useful alternatives. The original wireless setup requires disconnecting Ethernet and selecting the appropriate active adapter. Treat wired and wireless networking as separate arrangements rather than assuming simultaneous operation. USB Type-B is the computer interface, not evidence of unrestricted flash-drive printing.
AirPrint and Mopria Print are positively listed for suitable shared networking. Confirm the intended devices, firmware and discovery. The common guide's Wi-Fi Direct instructions are conditional, so exact peer-to-peer support needs separate confirmation. Ordinary built-in Wi-Fi and Wi-Fi Direct should not be used as interchangeable labels.
The original manual also documents protected computer jobs: Windows Print and Hold, Mac AirPrint PIN Printing or a suitable confidential-job driver option, followed by local release using a four-digit PIN. Check the full application and firmware routine. A normal mobile print button does not necessarily submit the same protected job, and job-expiration settings remain relevant.
Use the ordinary-paper path and capacity correctly
The 250-sheet drawer and 100-sheet multipurpose feeder total 350 sheets on the stated 20-pound or 75-gsm basis. Letter, Legal and A4 fit both sources and automatic duplex in the original table. Set guides and size/type to match the media, with matching settings for linked ordinary-paper loads.
Suitable envelopes have a separate one-sided multipurpose-feeder routine. They are not automatic-duplex or main-drawer stock. The separate output bin holds 150 sheets, so a larger queue still needs collection. If a 550-sheet expansion is actually installed, ensure the driver recognizes the option before relying on it.
Maximum one-sided Letter output is declared at 42 pages per minute, with duplex separately 18 Letter sides per minute. These are manufacturer modes, not article measurements. Maximum duty is separately 80,000 pages and does not extend the ordinary 8,000-page recommended monthly ceiling.
The B34 supply range and installation checks
The original US starter toner declares 3,000 pages. B341000 replacements declare 1,500, B341H00 3,000 and B341X00 or B340XA0 6,000 under ISO/IEC 19752. The separate 40,000-page imaging unit uses its own job and coverage basis. Match geographical cartridge restrictions and Return Program terms rather than turning yield into an unsupported current running-cost claim.
The body measures 14.5 inches wide, 14.3 deep and 8.7 high at 20.6 pounds. Allow loading and service access, inspect the electrical label and verify usable software. Compare a positively documented larger supply range when toner changes dominate the routine, or scanner-equipped hardware when paper capture is required.

Paper handling
Included 250-sheet drawer and 100-sheet multipurpose feeder total 350 at 20 lb/75 gsm. Letter, Legal and A4 fit both ordinary sources and automatic duplex. Match guides and size/type. Suitable envelopes use a separate one-sided multipurpose routine. One optional 550-sheet drawer raises maximum to 900 and is not included.
Scanning arrangement
Official hardware classification is print-only monochrome laser. Generic AirScan, Mopria Scan and scan/fax driver text do not add a scanner, copier, fax or ADF.
Computer and mobile connections
Included 802.11b/g/n Wi-Fi, 10/100BaseTX Ethernet and USB Type-B computer. Choose one active network arrangement; original Wi-Fi setup requires disconnecting Ethernet. AirPrint/Mopria use suitable shared networking. Wi-Fi Direct remains unestablished by conditional common-guide instructions.
Supplies and declared yields
US supplied Return Program toner 3,000 pages. Exact B341000 replacement 1,500; B341H00 3,000; B341X00/B340XA0 6,000 under ISO/IEC 19752. Separate 55B0ZA0 imaging unit 40,000 has its own job/coverage basis. No MS431 55B 20,000-page toner option borrowed; geographical restrictions and Return Program terms apply.
Software and support
Two-line monochrome LCD with buttons. Original guide documents Windows Print and Hold plus Mac AirPrint PIN Printing or compatible driver confidential jobs, with four-digit PIN and panel release. Confirm actual software/firmware and job controls; not every mobile print button submits a protected job. Exact AirPrint/Mopria protocol listings and shared-network conditions apply.
Electrical edition and setup
Exact US model and unit-body dimensions established. Nominal mains input remains unestablished in the read sources; inspect actual rating label and correct cord. Allow paper loading, output and service access beyond the closed body.
