Pocket sticker printer

The D21 is a pocket-sized thermal label printer that creates 57 millimetre stickers without ink. It connects over Bluetooth and weighs only .36 pounds, so it can travel in a bag or pocket for on-the-go labelling.

Casual creators and gift buyers

Suits anyone who wants quick, ink-free stickers for notes, gifts or kids’ crafts. Not for buyers who need wide-format labels, high-volume roll printing or wired network integration.

Simple Bluetooth pairing

Pair the printer with the companion app on a phone and start printing in seconds. The main friction point is keeping the small 57 millimetre roll aligned so the cutter clears cleanly.

Questions about this item

Does this D21 thermal printer need a smartphone or tablet to print stickers?

Yes — the printer connects by Bluetooth and is driven by the NADA Print App, so a compatible phone or tablet running that app is required to send print jobs.

Can I keep using my existing USB label printer while adding this Bluetooth model?

The D21 uses only a Bluetooth interface, so it operates independently of any USB printer you already own; both can stay connected to the same device without conflict.

How do I confirm the D21 is printing at the specified 2.24 inch width after pairing?

Print a test label from the NADA Print App and measure the output — it should be 2.24 inches across, matching the printer’s stated print size.
