Compact Bluetooth label printer for mobile use

The Nelko P21 is a pocket-sized thermal label printer that connects to iOS and Android phones via Bluetooth. It prints black text at 203 DPI on thermal paper without ink or toner. The package includes the printer and three starter tape rolls for immediate use.

Check phone compatibility

The printer requires the Nelko app from Google Play or the App Store and pairs through the app, not system Bluetooth settings. It does not work with computers and is incompatible with Google phones running Android 14. iOS users must update the app to version 4.8.0 for proper operation.

Portable build with rechargeable battery and tape

The unit measures 16.89 cm by 11.43 cm by 4.82 cm and weighs roughly half as much as traditional label makers. A built-in rechargeable battery supports extended mobile printing; a charging adapter is not included. Tape widths of 12 mm, 14 mm and 50 mm are supported, and colour labels are possible using patterned tapes.

Questions about this item

What comes in the box with the Nelko P21 and what must I buy separately?

The package includes the P21 printer and 3 label rolls. A charging adapter is not included, so you will need a USB power source to recharge the built-in battery. Additional tape rolls in other sizes or colours are sold separately.

Which label size should I choose for the P21 — 12x40mm, 14x40mm or 14x50mm?

All three widths fit the 14mm maximum print width. The 14x40mm tapes are the most common and come in the widest colour range, including transparent, starry-sky and green shades. Choose 12x40mm for narrower labels or 14x50mm white when you need a longer print area.

What does the 203 DPI rating mean for everyday labels printed on the P21?

At 203 DPI the printer produces sharp black text, icons and barcodes on thermal paper without ink or toner. It is ideal for address labels, file folders, school supplies and small shipping tags, but not for photo-quality graphics.
