What you get
- Printing in a pocket format — a 113×80×38 mm body weighing 0.15 kg takes up about as much room as a wallet.
- No ink at all — thermal printing develops the image on thermal paper, so paper is the only thing you ever buy.
- Clear text — 203 dpi is enough for lists, timetables, formulas and short notes.
- Wireless connection — Bluetooth 4.0 lets you print from your phone without cables.
- Freedom from sockets — the 1000-mAh battery lets you print wherever you are.
- A check before printing — the app previews the image and keeps a history of prints.
Who it is for
School and university students printing short notes, formulas or timetables. People who keep to-do lists and reminders on paper. Anyone who works with small stickers and labels. A gift for a child or an adult who likes planning and decorating their notes.
Who should skip it
If you need colour output, this printer only prints in black and white. It is not meant for full-size documents, as it is a pocket device. It prints only on thermal paper; regular office paper will not work.
