Portable thermal label printer

The NIIMBOT B21 is a compact Bluetooth thermal label printer designed for small businesses, crafters and retailers who need to produce address, barcode, price or ingredient labels on demand. It prints on media up to 2 inches wide and runs from a built-in 1200 mAh lithium battery. The unit ships with one roll of 2 by 1.2 inch label paper.

Sustained operation on battery

A single charge provides up to 4 hours of continuous printing, after which the device powers down automatically following 15 minutes of inactivity to conserve energy. Thermal technology eliminates the need for ink, toner or carbon ribbons, so consumable costs remain limited to label rolls. The 1 GB onboard memory holds print jobs while the Bluetooth link stays active.

Build and everyday connectivity

The printer measures 5 by 6 by 13 centimetres and weighs .7 pounds, making it easy to carry between workstations or market stalls. Bluetooth is the sole interface, pairing with phones or PCs running the NIIMBOT app for image recognition, Excel batch printing and 1D or 2D code scanning. Pre-cut label tapes in sizes such as 50 by 30 mm, 50 by 50 mm round, 34 by 34 mm, 40 by 30 mm and 50 by 70 mm are compatible. Buyers who need wired Ethernet, USB host printing or wider than 2 inch output should consider other equipment.

Questions about this item

How quiet and cool is the B21 when it runs for hours on the 1200 mAh battery?

Thermal printing means no ink or toner heat. One charge lasts about 4 hours of continuous work, and the unit auto-shuts off after 15 minutes idle to save power and keep it cool.

What phone or computer do I need to pair with the B21 Bluetooth label printer?

The NIIMBOT app runs on iOS and Android phones, and on Windows or Mac via Bluetooth. No cables or separate driver discs are required.

Will my existing NIIMBOT B1 or B3S label rolls fit the B21?

Yes. The B21 accepts the same pre-cut tapes — 50×30 mm, 50×50 mm round, 34×34 mm, 50×50 mm clear, 40×30 mm white or clear, and 50×70 mm white labels.
