The Nelko P21 is a portable Bluetooth label printer that prints from a phone. It is about half the weight and size of a traditional label maker and can slip into a pocket. It uses BPA-free direct thermal printing at 203 DPI, so it needs no ink or toner, and it has a built-in rechargeable battery.
The printer works with iOS and Android phones through the Nelko app. To set it up, download the app, install the paper roll, connect the P21 over Bluetooth in the app, and choose a template. The app includes more than 90 fonts, 10+ languages and 450+ materials. Labels can include text, QR codes, barcodes, images, the time and borders.
Printing is monochrome, black text only. Color labels need color-patterned label tape. Label lengths are fixed, and continuous label tape is not supported. The green sticker on the back of the label strip must not be torn or damaged, or print quality is affected. The printer does not work with computers and is not compatible with Google phones running Android 14.
