Mobile users needing colour labels

Suits anyone printing colour-coded shipping, bakery or craft labels from a phone or tablet without a subscription fee. Not for buyers who need pad compatibility, Ethernet or Wi-Fi connectivity, or a built-in keyboard for standalone operation.

Bluetooth and USB interface

The printer communicates over Bluetooth for mobile devices and USB for Windows PCs. It does not offer Ethernet, Wi-Fi or serial ports, so networks without Bluetooth or USB host support cannot use it directly.

Questions about this item

Should I choose the 1‑inch or 2‑inch label width for my B21 Pro?

The B21 Pro accepts rolls from 20 mm (0.8 in) up to 50 mm (2 in). The printable area is 48 mm wide, so 2‑inch labels use the full width while narrower rolls leave a small margin.

What does the 300 dpi resolution mean for my printed labels?

At 300 dpi the printer produces sharp text, detailed graphics and scannable QR codes on every 48 mm‑wide label, and it can also print red and black together when you use the special two‑colour paper.

How does the Bluetooth connection work with the NIIMBOT app?

Pair the printer with Android or iOS via Bluetooth, select the B21 Pro model in the free NIIMBOT app, and you can design labels with fonts, borders, symbols, Excel import, QR codes and OCR — no subscription required.
