Pocket-Sized Thermal Printer

The Nelko P21 is a compact Bluetooth label printer that fits in a pocket and weighs 0.26 kilograms. It prints monochrome labels up to 14x75mm using direct thermal technology at 203 DPI. The device targets home, school and office users who need quick, inkless labelling on the move.

App-Driven Template Library

A rechargeable battery powers the unit without an included charging adapter. The companion app supplies 3600 icons, 700 borders, 5500 materials and 750 templates across 29 languages. Users select a template, edit text, QR codes, barcodes or images, then send the job wirelessly from an iOS or Android phone.

Bluetooth-Only Connectivity

The printer pairs exclusively through the Nelko app over Bluetooth and does not support direct computer connections. Android 14 devices are not compatible, and iOS users must run app version 4.8.0 or later. Media is limited to a single 14x75mm roll with a maximum print speed of 30 mm per second.

Questions about this item

How often will I need to replace the thermal label rolls for the 14x75mm media size?

The P21 uses direct thermal printing with no ink or toner, so only the label rolls need replacing. Each roll contains 14x75mm labels and the printer holds one roll at a time.

What limits continuous printing on the Nelko P21 before it must pause?

The built-in rechargeable battery powers extended sessions, and the 203 DPI thermal print head runs at 30 mm/s. The app includes 750 templates and 5500 materials for batch jobs.

How much noise and heat does the P21 produce during all-day label printing?

Direct thermal technology runs silently with no moving print head, and the compact 6.65x4.5x1.9 in body stays cool during monochrome output at 203 DPI.
