Overview
The NIIMBOT B4 is the wide-format member of the range for merchant mobile-money solutions — producing large, highly visible QR payment labels for counters, kiosks and collection points. This 4-inch battery-powered thermal printer prints up to 104 mm wide at 203 dpi and 80 mm/s over Bluetooth or USB. Automatic paper positioning and smart media recognition handle gap, black-mark and transparent stock, while the 16,000-template library also supports logistics, retail and asset-management labels.

- Warehouse and logistics labelling for device fleets
- RFID-enabled asset tagging of enrolment hardware

Key Capabilities
104 mm Print Width

80 mm/s Print Engine
Prints up to 80 mm/s with a print head rated for 50 km of service life, for sustained batch runs rather than occasional labels.

2,000 mAh battery in a 757 g, 157 × 135 × 69 mm body — untethered operation across a warehouse floor or a field deployment.
RFID & Smart Recognition
RFID support with automatic paper positioning and smart media recognition across gap, black-mark and transparent stock.
16,000+ Templates
A template library spanning logistics, retail, warehousing and asset management, with batch printing for serialised runs.
