Our take
Brother's HL-5140 is a monochrome printer with a 21-page-per-minute Letter rating, a standard 250-sheet paper tray, and USB 2.0 plus a parallel interface. It is a focused option for a computer or print server already using a local connection. Two practical limits are explicit: duplex is manual, and Ethernet is an optional NC-2100p network print-server accessory rather than a built-in port on the standard unit. Brother marks the model discontinued, and the reviewed sources do not give a recommended monthly volume.
A direct-connected monochrome printer for an existing USB or parallel setup, when optional networking and automatic duplex are not requirements..
Do not choose the standard HL-5140 if you need built-in Wi-Fi, ready-to-use Ethernet, automatic duplex, or copy and scan functions.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Brother rates the printer up to 21 ppm on Letter paper.
- The standard paper tray holds up to 250 sheets, with an additional optional tray documented.
- Standard USB 2.0 and IEEE 1284 parallel interfaces cover older direct-connected setups.
What to weigh up
- The base configuration does not include Ethernet; the NC-2100p accessory is optional.
- Brother documents manual rather than automatic duplex printing.
- The reviewed exact-model source provides no recommended monthly page range, and Brother marks the model discontinued.

What the features mean for you
A single-function monochrome workflow
The HL-5140 is built around black-and-white printing, so it can fit invoices, letters, and office forms where color is not required. Brother describes electrophotographic printing and rates Letter output up to 21 pages per minute. It has no documented copy, scan, or fax functions, so it should not be compared with an all-in-one as if they offer the same workflow. If documents need to be digitized at the same desk, pair it with a separate scanner or choose an MFP whose feeder and scan features match the task.
Direct connections are standard; networking is extra
Brother lists Hi-Speed USB 2.0 and an IEEE 1284 parallel interface as standard. A 10/100Base-TX network connection is available through the optional NC-2100p print server. That distinction matters when replacing a directly connected printer: a buyer should not assume a base HL-5140 can join Ethernet by plugging in a cable. The documented optional accessory could support a networked setup, but its presence and operation must be verified on the exact unit. No built-in wireless interface appears in the reviewed product specification.
Manual two-sided output takes extra handling
Brother lists manual duplex. The HL-5140 can be used for two-sided pages, but the user must turn and reload the stack according to the print instructions. That can be acceptable for occasional packets, yet it adds handling to every longer report and does not match a requirement for automatic page turning. The 250-sheet tray keeps routine paper loading straightforward; Brother also documents an optional second 250-sheet tray. This model does not qualify for the automatic-duplex finder paths, even though it can produce manually duplexed pages.
Tray and feed details help set a realistic routine
The standard tray holds up to 250 sheets, the manual feed accepts one sheet, and an optional second tray can add another 250. The output path holds up to 150 sheets face down. Brother lists Letter and Legal among supported sizes and also gives media weight limits for the main tray and manual feed. That supports ordinary document work and selected specialty pages, but it does not turn the printer into a high-capacity departmental device. If a queue runs continuously, the user should account for manual duplex and paper replenishment rather than relying on the speed figure alone.
Treat support and workload as separate checks
Brother's U.S. support page marks the HL-5140 discontinued. The exact specification reviewed here does not state a recommended monthly page range, so the finder keeps both volume endpoints unknown. Discontinued status does not describe the condition of a particular printer or prove that every part or driver is unavailable. Before selecting a used unit, confirm the exact included connection card, check that the intended computer can use a compatible driver, and inspect toner and drum condition. Those checks address the actual unit instead of assuming its history from the model name.
What else to compare
Choose a mono printer with standard Ethernet for ready network sharing, or automatic duplex for recurring two-sided reports.
Before you buy
Does the base HL-5140 include Ethernet?
No. Brother lists Ethernet through the optional NC-2100p print server accessory rather than the standard interfaces.
Can it automatically print on both sides?
No. Brother's specification identifies manual duplex, which requires the user to handle the paper between sides.
What monthly volume does Brother recommend?
The reviewed HL-5140 specifications do not provide a recommended monthly page-volume range.

The decision
The HL-5140 can serve a direct-connected monochrome desk, but manual duplex and optional networking narrow its fit for a modern shared queue.
