Pocket-Sized Bluetooth Label Printer

The Nelko P21 is a compact thermal label printer that connects to iOS and Android phones via Bluetooth. It weighs 0.249 kilograms and measures 2.4 by 3.96 by 1.3 inches, so it fits in a pocket for on-the-go labelling at school, in the office or at home.

203 DPI Print Head With App Templates

The direct thermal engine prints at 203 DPI without ink or toner, producing black text on white or colour-pattern tapes. The Nelko app supplies 750 templates, 3600 icons, 700 borders and 5500 materials across 29 languages. Print size is 14 by 40 by 14 inches; media rolls measure 14 by 75 by 14 inches. The printer does not work with computers and is incompatible with Android 14 devices.

Rechargeable Battery And Silent Thermal Operation

A built-in rechargeable battery powers extended printing sessions; no charging adapter is included. Direct thermal technology runs silently and generates minimal heat during normal use. The unit ships with three label rolls and a portable cutter. iOS 13 or later is required, and the app must be updated to version 4.8.0 for full functionality.

Questions about this item

Will the 2.4 in × 3.96 in × 1.3 in P21 sit on a shelf next to a desktop label printer without taking much space?

Yes, the P21 measures 2.4 in × 3.96 in × 1.3 in and weighs 0.249 kg, so it fits easily beside larger desktop units.

How do I know the 203 DPI thermal print head is working correctly after I pair the P21?

Open the Nelko app, select a template, and print a test label; sharp black text at 203 DPI confirms the print head is functioning.

The box lists labels — do I need to buy a charging adapter or extra tapes separately?

The package includes label tapes; a charging adapter is not included, so you will need a standard USB charger, and additional tapes can be purchased when required.
