Our take
OKI identifies the B4400 as a monochrome page printer with an LED array. The B4400 column in the series brochure lists up to 27 pages per minute, a standard 250-sheet tray, USB, and parallel; the base B4400 uses optional OkiLAN print-server hardware for Ethernet, unlike a network-equipped suffix model. A second 500-sheet tray is optional. The saved sources do not establish automatic or manual duplex, wireless, or a recommended monthly range. This is a simple legacy direct-connection model, not a multifunction device or a laser-engine printer.
A buyer considering a legacy, direct-connected monochrome LED printer who can verify the exact B4400 configuration, condition, supplies, and computer compatibility..
Do not choose the base B4400 when built-in Ethernet, Wi-Fi, automatic duplex, copy or scan functions, or a documented recommended monthly range is required.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The brochure identifies a standard 250-sheet input tray and a 27 ppm monochrome rating for the B4400 column.
- USB and parallel are documented standard interfaces for the base configuration.
- An optional second 500-sheet tray can expand input capacity when that accessory is present.
What to weigh up
- Ethernet requires optional OkiLAN print-server hardware; the base B4400 is not the B4400n configuration.
- The saved sources do not establish manual or automatic duplex or a recommended monthly range.
- The 2007 user guide does not by itself establish current driver compatibility or the condition of an offered unit.

What the features mean for you
Do you need a mono print-only LED device?
The B4400 is a monochrome print-only device. OKI's U.S. user guide identifies an LED array, so this is a toner-based LED printer rather than a model to describe as a laser-engine printer. That distinction keeps the technology label accurate while leaving the product in the same toner-printer buying context as the other reviewed OKI units. Its role is limited to black-and-white output; a buyer who also needs copy, scan, or fax functions should compare an MFP instead of adding those capabilities by assumption. The series brochure rates the B4400 at up to 27 pages per minute.
Does the 250-sheet reserve fit your work?
The B4400 brochure lists a standard 250-sheet tray and a single-sheet manual feed path. An optional second 500-sheet tray can raise total input to 750 sheets, but that accessory is separate from the base configuration. A buyer comparing listings should ask whether the second tray is included rather than treating maximum capacity as standard. The 250-sheet tray gives a modest reserve for ordinary documents, while the manual feed is a separate path for occasional use. Neither capacity says how many pages OKI recommends printing each month, so keep monthly workload guidance unknown.
Can optional Ethernet meet your network need?
OKI lists USB and parallel as standard interfaces for the base B4400. The brochure describes OkiLAN internal or external print-server equipment as the path to Ethernet for the non-network model, while the B4400n is a different configuration. Do not count an optional server as included or assume that a particular older server will work on a current office network. The saved exact-model sources also do not establish built-in wireless. Confirm the product label, visible ports, and any accessory part number before choosing this printer for shared access.
What does the speed rating say about volume?
The brochure's up-to-27-page-per-minute figure is a manufacturer rating, useful for comparing nominal output class but not a promise for every document or individual unit. The shared B4400/B4600 materials also show a maximum duty-cycle ceiling, which is not a recommended monthly target. Because the reviewed packet gives no recommended monthly range for this B4400 configuration, a buyer should not infer a safe routine volume from its speed, tray capacity, or a maximum figure. For business use where monthly guidance is part of purchasing approval, choose a printer with a published recommended range.
What should you check on a legacy unit?
OKI's U.S. manual is dated 2007 and describes toner and a separate image drum, as well as cleaning the LED array during upkeep. Those details explain what routine ownership may involve, but they do not prove that a particular seller's machine has fresh supplies or that its drivers suit a current computer. Ask for a photo of the B4400 label and ports, a printed sample, the drum and toner status, and confirmation of any included print server or second tray. Check operating-system compatibility and return terms before buying; this review does not claim current stock, price, or working condition.
What else to compare
Choose a network-equipped B4400n only after verifying that exact configuration, or select a newer mono printer if Wi-Fi, automatic duplex, or current support is important.
Before you buy
Is the B4400 a laser printer?
OKI's U.S. user guide identifies an LED array; the B4400 uses toner-based LED imaging rather than a laser imaging engine.
Does the base B4400 include Ethernet?
No. The base B4400 lists USB and parallel; Ethernet requires optional OkiLAN print-server hardware, while B4400n is a separate configuration.
Does it support automatic duplex?
The exact B4400 sources reviewed here do not establish duplex printing, so do not assume automatic or manual two-sided output.
