Portable Thermal Label Printer

The NIIMBOT B21 is a pocket-sized thermal label printer that connects over Bluetooth and prints on 0.8-inch to 2-inch wide label rolls. It targets small retailers, crafters and home organisers who need price tags, barcodes, address labels or gift stickers without the cost of ink or toner cartridges.

Sustained Thermal Operation

Thermal printing means the only consumable is the label roll itself, so there is no ink to dry out or ribbon to replace during long sessions. A single charge delivers up to 4 hours of continuous printing and the unit powers down automatically after 15 minutes of inactivity to preserve battery life.

Bluetooth Pairing and Media Lock

Pairing is handled through the NIIMBOT mobile app, which also provides fonts, templates and Excel batch printing. The printer only accepts genuine NIIMBOT label rolls that carry the required RFID tag; third-party media will not be recognised and cannot be used.

Questions about this item

How long does the battery last when the printer runs continuously all day?

One charge supports four hours of working time and the device shuts down automatically after fifteen minutes of inactivity to save power.

What label rolls must I already own before the B21 will print?

The printer only recognises authentic NIIMBOT labels that contain the required RFID; third-party rolls will not work.

Will the B21 connect to an older laptop that only has USB ports and no Bluetooth?

The unit communicates solely through Bluetooth, so a computer without Bluetooth cannot send print jobs to it.
