Nelko P21 Bluetooth Thermal Label Maker with 3 Rolls and Case
Product description
The included 14 × 40 mm white label rolls give the Nelko P21 a ready-to-use format for naming school supplies, sorting household items or adding clear labels to office materials. This compact thermal printer connects to a phone over Bluetooth and prints in black without ink or toner.
Create a label in the Nelko app, choose a template and send it to the P21. The supplied case keeps the printer and its label rolls together between tasks.
Why it’s worth it
Thermal printing keeps label-making simple: the P21 prints black text at 203 dpi without ink or toner cartridges. Its monochrome output suits everyday tasks such as marking notebooks, identifying food storage, organizing cosmetics and adding reminder or price labels. The app lets you build designs with text, QR codes, barcodes, images, icons and borders, so labels can carry more than a name alone.
With Bluetooth printing from an iOS or Android phone, you can prepare a label where the items are being sorted instead of moving to a computer and full-size printer. The app includes templates and design elements to help create labels for classroom materials, mailings and shared office supplies. Buyers also highlight the compact format and quick printing for school and organizing tasks, though feedback on Bluetooth connections and the label-making experience is mixed.
Worth noting
The P21 prints black only. Patterned label tape can add colour to the label’s background, while the printed text remains monochrome. Label lengths are fixed, listed formats include 14 × 40 mm, 14 × 50 mm and 14 × 75 mm. Continuous label tape is not supported, so the P21 is designed for individual, set-format labels rather than cut-to-length strips.
It connects through Bluetooth using the Nelko app on a compatible iOS or Android phone, it does not work with computers. It is also not compatible with Google phones running Android 14. For iOS, the manufacturer advises using the latest version of the Nelko app. Keep the green sticker on the back of the label strip intact, as damaging it can affect printing.
How to use it
Install a label roll, download the Nelko app from the App Store or Google Play, then pair the P21 from within the app. Choose a template or make a design with text and other elements, and print. For a quick classroom setup, create name labels for notebooks and personal supplies, at home, use the same process to identify storage containers or cosmetics. The included three rolls of white label paper, case and USB-C charging cable help keep the printer and its supplies together.
What to clarify
Which phones can connect to the P21? It connects by Bluetooth through the Nelko app on iOS and Android phones. It does not work with computers, and Google phones running Android 14 are not compatible.
Does it print in colour? No. The P21 prints black only. Patterned label tape can provide a coloured design behind the black print.
What comes with the printer? The listed pack includes the P21 label maker, a case, a USB-C charging cable and three rolls of white label paper.
When it makes sense
The Nelko P21 suits people who want a phone-controlled label maker for recurring, small-format organization at school, home or work. Its inkless black printing, app-based design options and included rolls make it practical for names, reminders and item identification, with a case for keeping the compact setup together between uses.
