Our take
Brother identifies the HL-4070CDW as a color electrophotographic printer for printing only. Its listed maximum print speed is up to 21 pages per minute on Letter paper, and automatic two-sided output is specified at up to 7 sides per minute. The exact model includes a 250-sheet tray and 50-sheet multipurpose feed, plus USB, Ethernet and 802.11b/g wireless. Brother does not give a recommended monthly range in the checked U.S. specification. The CDW suffix matters: keep this wired-and-wireless duplex configuration distinct from related HL models with different interfaces or optional duplex hardware. Its age makes software support and unit condition important parts of the decision.
A shared workgroup that needs color-only printing, built-in Wi-Fi and automatic two-sided output, and can verify support for a legacy printer..
Avoid it if you need scanning, copying or faxing, if modern Wi-Fi security is mandatory, or if you need a documented monthly recommendation.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Brother documents color print-only operation with built-in Ethernet and 802.11b/g wireless.
- Automatic duplex is listed, with a separate rated two-sided throughput figure.
- The standard 250-sheet tray and 50-sheet multipurpose feed allow a second paper route.
What to weigh up
- Brother's reviewed specification does not state a recommended monthly range.
- The 7 sides-per-minute duplex rating is lower than its 21 ppm simplex speed rating.
- Legacy driver, network security and consumable support need checking for the actual setup.

Full review: how the features affect your choice
What the features mean for you
Print-only color output
Brother's product specifications identify the HL-4070CDW as a color electrophotographic printer, not an all-in-one. It is suited to a shared queue for color pages and ordinary text, but it cannot replace a scanner, copier or fax machine. The manufacturer lists up to 21 pages per minute on Letter paper. That is a rated maximum; document complexity, host software, media and connection can change actual job time. Keep it separate from nearby Brother models whose suffixes indicate different networking or paper handling. Confirm the label reads HL-4070CDW rather than treating a family name as proof of this exact configuration. ([Brother HL-4070CDW specifications](https://support.brother.com/g/b/spec.aspx?c=us&lang=en&prod=hl4070cdw_all)).
Automatic duplex has its own speed rating
Brother lists automatic two-sided printing for this exact model and rates duplex output at up to 7 sides per minute, alongside a simplex rating of up to 21 pages per minute. Those numbers should not be compared as if they describe identical jobs: automatic two-sided pages take a different path through the engine. Duplex is useful for internal reports and handouts where reduced paper use matters, but buyers should test registration and feeding on the specific older unit. The source does not separately confirm a manual-duplex mode. The product profile therefore treats automatic duplex as established and leaves the manual mode unknown.
Three supported connection routes
Brother lists USB, Ethernet and 802.11b/g wireless. USB serves a direct workstation; Ethernet supports a wired shared queue; Wi-Fi allows placement where an Ethernet drop is unavailable, subject to the printer and access point supporting a compatible security setup. The document specifies older 802.11b/g standards, so do not assume it supports every modern authentication option. Check the intended operating system and network before relying on the wireless path. These interface facts describe the model's standard configuration and do not establish that any particular used printer has an intact wireless radio or working port.
Paper capacity for short shared runs
The listed paper handling includes a 250-sheet main tray and a 50-sheet multipurpose feed. The second route is useful for occasional alternate media without emptying the main tray, although compatibility still depends on the chosen stock and the manual's limits. Brother does not state a recommended monthly volume in the reviewed specification, so neither the tray capacity nor its 21 ppm rating should be used to invent a workload threshold. For a regular departmental queue, compare paper use, color frequency and maintenance support with a newer model whose routine volume is specified. Inspect tray parts and feed behavior on an older unit before committing it to unattended printing.
Check legacy support before relying on it
This is an older model, and its official feature page does not provide a current support guarantee or recommended monthly range. Confirm that a suitable driver remains available for the computers that will send jobs, and that the specified wireless generation works with the network's settings. A current seller listing may combine the printer with supplies or accessories, but those are not part of Brother's standard specification unless individually documented. Ask for a model-label photo and a print sample on both sides. If predictable color cost, current security compatibility or managed fleet support is central, compare a current-generation printer instead of inferring those qualities from this model's original ratings.
Compare for your needs
For a current wireless color printer compare a newer exact model with supported drivers and a published recommended volume; for all-in-one tasks select a color MFP.

The decision
The HL-4070CDW delivers color, wireless connectivity and automatic duplex in a print-only package, but its older network standards and unknown recommended workload merit a setup check.
