Niimbot B4 Space Blue is a portable thermal label printer designed for simple, on-the-go label creation. It pairs with smartphones and tablets via Bluetooth and also supports USB connection. The device uses direct thermal printing so no ink or toner is required, and it accepts label rolls from 20 to 108 mm wide. The compact, battery-powered design with a 2000 mAh rechargeable battery makes the printer suitable for retail, warehouses, shipping and other environments where mobile, reliable label printing is needed.
Advantages
The Niimbot B4 prints quickly and precisely with a resolution of 203 dpi and speeds up to 80 mm/s. Thermal printing eliminates the need for consumable ink or toner, reducing operating costs. Printed labels are durable — waterproof, oilproof, scratch- and tear-resistant — thanks to a multi-layer material construction. The device supports automatic label detection and positioning and RFID recognition of label type and size, reducing setup errors and material waste. It also supports batch printing and up to 10 simultaneous users via the mobile app.

Use the mobile app to select a template or design a custom label, adjust size and content, then send the job to the printer. The printer will automatically recognize label type and position the print to minimize waste. For batch jobs, create and queue multiple labels in the app before printing.
Usage recommendations
Use Niimbot-approved thermal labels sized within the supported range (20–108 mm) for optimal print quality and durability. Keep the print head clean and avoid abrasive materials to extend the print head life. Charge the battery before prolonged mobile use and store the device in a dry environment to maintain label adhesion and device reliability.
