Brother TJ-4121TN Industrial Label Printer (TJ4121TNZ1)

The Brother TJ-4121TN is a 4-inch industrial label printer for manufacturing, warehousing, logistics, healthcare and retail sites that print labels in medium to high volumes. As a thermal transfer printer it uses ribbons up to 450 m long – with the ink coated on the inside or the outside – for durable, smudge-proof labels on paper and synthetic materials, and it also prints on direct thermal labels without a ribbon. It prints 300 dpi labels up to 105.7 mm wide at up to 178 mm/s, takes label rolls up to 203 mm in diameter on cores from 25.4 to 76.2 mm and connects via USB, USB Host, RS-232 serial and Ethernet as standard, while ZPL2, EPL2 and DPL emulation makes it easy to integrate into existing systems. This version, TJ4121TNZ1, is the 300 dpi model with a 3.5-inch colour touchscreen and six-button navigation – sharp output for small text and fine 2D codes, with easy set-up on the printer itself.

Key Features

• Built for industrial workloads – a compact printer only 248 mm wide that holds 203 mm label rolls on cores up to 76.2 mm, backed by Brother's 5-year warranty.
• Thermal transfer with 450 m ribbons – 40–110 mm wide ribbons on a 1-inch core, with the ink on the inside or the outside: fewer ribbon changes and a wide choice of supplies; direct thermal labels work too.
• 300 dpi at up to 178 mm/s – sharp small text, logos and fine 2D codes at up to 7 ips across a 105.7 mm print width.
• Flexible media handling – media 20–120 mm wide and 0.06–0.28 mm thick: continuous, die-cut, black-mark, notched and fan-fold, with gap and black-mark sensors.
• 3.5-inch colour touchscreen – set up, calibrate and check the printer directly on the colour display, with six-button navigation and menus in 11 European languages.
• Connected as standard – USB 2.0, RS-232 serial and 10/100 Ethernet, plus USB Host for a keyboard, scanner or flash drive in stand-alone mode; the optional user-installable Wi-Fi module (PA-WI-002) adds wireless networking.
• Drop-in replacement – FBPL-EZD emulates ZPL2, EPL2 and DPL (FBPL-EZS also SBPL), so existing label formats keep working; BarTender Ultra Lite, Brother Printer Management Tool and Windows, Android and iOS SDKs are available.
• Ready to grow – dealer-installable label peeler with liner rewinder (PA-LP-005) and cutter (PA-CU-004), plus a replaceable printhead and platen roller.

• Warehousing and logistics – shipping, receiving, picking and pallet labels
• Healthcare and laboratories – sample, pharmacy and asset tracking labels
