Ultra-compact Bluetooth label printer

The Nelko P21 is a pocket-sized all-in-one label maker that connects wirelessly to iOS and Android phones. It prints at 203 DPI using direct thermal technology, so no ink or toner is required. The device measures 3.74 in x 1.65 in x 6.3 in and includes a rechargeable battery for portable operation.

Ideal for mobile organising.

This printer suits teachers, parents and small-business owners who need quick labels on the move. It does not connect to computers, and it is incompatible with Google phones running Android 14, so buyers needing PC integration or that specific OS should look elsewhere.

Consistent output during extended sessions

The built-in rechargeable battery supports prolonged printing without a mains adapter, which is not included. Direct thermal printing maintains 203 DPI clarity across continuous label runs, and the app provides 750+ templates, 3600+ icons and 29 languages for sustained creative use.

Questions about this item

What smartphone operating system do I need to run the Nelko app for the P21 label maker?

The Nelko app works with iOS and Android phones, but it is not compatible with Google phones running Android 14.

Can I keep using my existing label tapes with the P21, or do I need Nelko-branded rolls?

For best printing results the manufacturer recommends using Nelko thermal label paper; the P21 prints black text on direct thermal tape and colour labels require colour-pattern tapes.

How do I confirm the P21 is printing correctly after I pair it with my phone?

Open the Nelko app, choose one of the 750+ built-in templates, send a test print and check that the output is sharp at 203 DPI with no missing dots.
