NIIMBOT B31 - Label Printer

The NIIMBOT B31 Portable Thermal Label Printer is a direct thermal unit designed for producing product identification, shipping, and organisational labels without ink or toner. It operates at a maximum resolution of 203 DPI and prints at speeds up to 80 mm per second. The printer supports media widths from 20 to 75 mm, accommodating a range of standard label formats. As a monochrome direct thermal device, it produces single-colour output suitable for standard barcode and text applications. The B31 uses heat-sensitive thermal labels rather than ribbons or cartridges.

Connectivity is provided via Bluetooth and USB Type-C, allowing direct connection to computers or wireless printing from mobile devices. The printer supports Windows, macOS, Android, and iOS, making it suitable for mixed-platform environments. An integrated 1500 mAh rechargeable lithium battery supplies portable power for use away from a wall outlet. Weighing 451 g, the ABS+PC housing gives the printer a lightweight form factor that is easy to carry between workstations. Automatic tape size detection reads the inserted media and adjusts the print settings accordingly, reducing manual configuration. There is no built-in display, so label design and print commands are managed entirely through the connected device.
