Pocket-Sized Thermal Label Maker

The Nelko P21 Primrose is a compact Bluetooth thermal printer that produces monochrome labels, QR codes and barcodes directly from a smartphone. It weighs roughly half as much as traditional desktop label makers and fits in a pocket for on-the-go organisation.

App-Driven Setup With One Caveat

Pairing is done through the Nelko app on iOS or Android; load the roll, connect via Bluetooth and choose from thousands of templates. The printer does not work with computers and is incompatible with Google phones running Android 14, so verify your device before purchase.

Ideal For Mobile Labelling, Not Desktop Workflows

Suits home organisers, small retailers and students who need quick, inkless labels from a phone. Buyers who require PC connectivity, colour printing or continuous high-volume output should consider a different class of printer.

Questions about this item

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

Open the Nelko app, select a quick template, and print a test label; the 203 DPI thermal output should appear as sharp black text or a readable QR code on the 15 mm wide tape.

What comes in the box and what must I buy separately?

The package includes the P21 printer and one labels-and-paper roll; a charging adapter is not included, so you will need a standard USB power source to recharge the built-in battery.

Which label sizes work with the P21 Primrose?

The printer supports 15 mm wide rolls in lengths of 30 mm, 40 mm, 50 mm and 75 mm, plus 12 mm x 40 mm and 14 mm x 40 mm sizes, all listed in the media specifications.
