Mobile receipt and label printer

The Brother RJ4230BL is a direct thermal mobile printer built for field workers who need to produce receipts, labels and tags on the move. It prints at up to 5 inches per second with a 203 dpi resolution and handles media rolls up to 58 mm wide. Bluetooth, USB and serial interfaces let it connect to iOS, Android and Windows devices without a fixed workstation. The 256 MB RAM and 42 MB user flash store fonts and formats for offline use.

Ultra-rugged IP54 housing with drop protection

A moulded rubber chassis and reinforced internals survive 6.88 ft drops and meet IP54 dust and moisture sealing for warehouse aisles or outdoor routes. The tear-up and tear-down cutter lets operators choose how media exits the 100 mm roll chamber. Industrial tactile buttons and a real-time battery indicator keep the printer usable with gloves or in low light. At 2.8 lb and 5.9 x 3.6 x 2.3 in it fits on a belt or in a vehicle mount.

Free Mobile Deploy app and smart Li-ion battery

The 3000 mAh battery is rated for a full shift and reports remaining capacity to the host device so teams can swap units before they die. Mobile Deploy handles remote firmware updates, configuration profiles and font management across a fleet without touching each printer. Fourteen bitmap and four outline fonts are built in, and additional fonts load through the downloadable manager. NFC one-touch pairing cuts setup time for new users.

Questions about this item

Which interfaces does the RJ4230BL use and what is the practical limit for wireless range?

It connects via Bluetooth, USB and Serial; the Bluetooth link works within typical Class 2 range of about 10 metres line-of-sight.

What roll size and core does the printer accept for it to fit in the compartment?

Maximum roll outer diameter is 2.28 in (58 mm) with a standard 0.5 in core; media width can be 2 in to 4 in.

How is the RJ4230BL set up for the first time and which step is often missed?

Charge the 3000 mAh Li-ion pack, drop in a roll, pair by tapping the NFC zone on an Android device or select the printer in Bluetooth settings, then install the driver or SDK; the step most people skip is running the free Mobile Deploy app to push firmware and configuration profiles before the first print job.
