Pocket Label Printer

The Nelko P21 is a thermal label printer that connects to a smartphone over Bluetooth. It prints text, QR codes, barcodes, images, timestamps and decorative borders without ink or toner. The rechargeable unit weighs 0.72 pounds and measures 6.65 by 4.5 by 1.9 inches, so it fits in a pocket or small bag for on-the-go labelling.

Mobile Users Who Want Simple Labelling

It suits anyone who creates labels directly from an iOS or Android phone using the Nelko app, which supplies 3600-plus icons, 700-plus borders, 5500-plus materials and 750-plus templates in 29 languages. Buyers who need to print from a desktop or laptop computer, or who require continuous label rolls, should look at a different class of printer.

Bluetooth-Only Connectivity

The sole interface is Bluetooth pairing through the Nelko app; no USB, Wi-Fi or wired link is provided. iPhones must run iOS 13 or newer, and the app must be updated to version 4.8.0 for full compatibility. Google phones running Android 14 are not supported.
