Mini sticker printer for kids and hobbyists

The D21 is a pocket-sized thermal label printer that connects over Bluetooth and prints on 57 mm media without ink or ribbons. It weighs 0.36 lb and measures 3.34 in by 3.38 in by 1.69 in, so it fits easily in a bag or pocket. The NADA Print app lets you design and print stickers, labels and notes from a phone.

Suits anyone who wants portable.

It is ideal for children, crafters and casual users who enjoy personalising belongings or printing quick labels on the move. Buyers who need wide-format labels, high-volume barcode rolls or a wired USB connection should look at something else.

57 mm print width on thermal media

The single specification that decides fit is the 57 mm (2.24 in) maximum print width on direct-thermal label rolls. If your labels are wider, this printer cannot accommodate them.

Questions about this item

How long can the 57 mm thermal print head run continuously before it overheats?

The D21 uses direct thermal printing with no ink ribbon, so sustained use is limited by the print head temperature rather than a duty-cycle figure; let it cool after extended sessions.

What is the noise level and heat output when the printer runs all day on Bluetooth?

The compact 3.34 x 3.38 x 1.69 in chassis has no fan; operation is quiet with only the paper feed motor audible, and warmth stays low because there is no ink heater.

Which smartphone operating systems and app does the D21 require for Bluetooth printing?

Pair the printer via Bluetooth with the NADA Print App on iOS or Android to create and send sticker designs from your phone.
