Pocket-Sized Bluetooth Label Printer

The Nelko P21 is a compact thermal label printer that connects to iOS and Android phones via Bluetooth. It uses direct thermal technology at 203 DPI to print black text on 14 mm wide labels without ink or toner. The device measures 1.9 by 4.52 by 6.65 inches and includes a built-in rechargeable battery for portable use.

Bluetooth-Only Mobile Interface

Printing is managed exclusively through the Nelko mobile app, which requires iOS 13 or later and is not compatible with Android 14 devices. The app provides 3600+ icons, 700+ borders, 5500+ materials, 750+ templates and 29 languages for label design. No computer connection or wired interface is supported, so all editing and print commands must come from a paired smartphone.

Replaces Bulky Desktop Label Makers

This printer suits users who need on-the-go labelling for classrooms, home organisation or small retail tasks and want to avoid the size and power requirements of traditional desktop units. It is not intended for high-volume continuous printing, wide-format labels, colour output or integration with PC-based inventory or shipping software.
