Our take
OKI's U.S. support page identifies the exact B412dn part 62444301, and the model's technical material describes a monochrome LED print-only device. Its listed A4 speed is 33 pages per minute, with automatic duplex, Ethernet, a 250-sheet tray and a 100-sheet multipurpose feed. Wireless is an optional feature rather than a standard assumption for the base configuration. A regional B412dn specification sheet gives monthly volume guidance for a different order code, so this article leaves the U.S. part's recommended monthly range unknown. The B412dn fits a wired mono queue where automatic two-sided output matters.
A wired mono print queue that needs automatic two-sided output and can use a 250-sheet cassette plus multipurpose feed..
Look elsewhere if built-in Wi-Fi, copy/scan/fax functions, or a verified monthly recommendation for the U.S. part is required.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- OKI documents automatic duplex and Ethernet for the B412dn model.
- The 250-sheet main tray and 100-sheet multipurpose feed provide separate paper paths.
- A 33 ppm A4 rating is listed in the original technical material.
What to weigh up
- Wireless is optional and not assumed standard for part 62444301.
- A regional product sheet's monthly range is not transferred to this exact U.S. part.
- The B412dn is print-only and does not provide copier, scanner or fax functions.

Full review: how the features affect your choice
What the features mean for you
Why does OKI call it an LED printer?
The B412dn technical material identifies a monochrome LED print engine. The product is evaluated here as an eligible electrophotographic office printer, while its exact engine description remains LED rather than being relabeled as a conventional laser mechanism. It is a print-only model, so it should not be compared as an MFP just because it belongs to a printer family. Offices that only need mono output may value its simple role; buyers who need copy, scan or fax should choose a separate multifunction configuration.
What does the 33 ppm A4 rating mean?
The reviewed technical sheet lists up to 33 pages per minute on A4. That is a manufacturer rating and not an observed result for every print job or individual device. Paper type, host, image complexity and warm-up conditions affect real operation. Use the speed to compare printer classes, then look at the automatic duplex and paper feed features that determine how the office uses it. The available U.S. exact-part record does not supply a recommended monthly band, so do not turn a speed figure into a sustained workload estimate.
How does its standard paper input help?
The original technical information lists a 250-sheet main tray and a 100-sheet multipurpose feed. The cassette can hold everyday stock, with the alternate path available for supported media or a different paper size. That can reduce interruptions when short jobs use envelopes or another stock, subject to the user guide's limits. Verify which trays are actually present on an individual unit and which weights are supported. Standard input capacity can inform refill planning, but it does not replace a recommended monthly volume for workload matching.
Is automatic duplex included?
OKI identifies automatic duplex for the B412dn. The mechanism turns supported sheets without the user handling the stack between sides, which helps with routine two-sided reports. Confirm media compatibility and driver settings before depending on it for specialty paper. This print-output function does not add document scanning or duplex capture: the B412dn is a printer, not a copier or scanner. If the office needs to process two-sided originals, it will need a separate scanner or multifunction unit, even though the printer can produce two-sided pages.
Will Ethernet or wireless fit your setup?
The base product documentation lists Ethernet. The reviewed regional material describes wireless as an option, so the standard U.S. B412dn should not be treated as Wi-Fi-ready without checking the exact accessory or adapter. A wired office can plan a direct Ethernet path; a wireless-only location should verify the installed option and supported driver configuration before purchase. This is a connection decision that can affect placement and IT setup. The product page's exact part identifier is useful for distinguishing the candidate from related B412 models with different suffixes.
What can you say about monthly workload?
A regional B412dn specification sheet lists a recommended monthly volume for its regional order code. The historical candidate, however, points to U.S. part 62444301, and the reviewed exact-part U.S. page does not establish that monthly range. The safe profile leaves the recommendation unknown rather than transferring the regional value without a U.S. mapping. The same caution keeps maximum duty figures separate from routine guidance. If workload is a hard filter, seek an exact part-specific U.S. recommendation or choose a model whose published range is already tied to its precise configuration.
Compare for your needs
Choose a model with built-in Wi-Fi if the network has no Ethernet drop, or a mono MFP if copy, scan and fax belong in the same workflow.
