NIIMBOT K3W Wi-Fi Blue - label printer

The NIIMBOT K3W Wi-Fi Blue Label Printer is a compact desktop thermal printer designed for monochrome labels in logistics, retail, clothing, jewellery, and food-labelling applications. Using direct thermal technology, it produces smudge-resistant output at 203 DPI without ink or toner. Print speed reaches 180 mm/sec, which supports continuous label runs in busy packing or retail environments. The printer accepts media from 20 mm up to 80 mm wide, with a maximum printing width of 80 mm, covering everything from small product tags to larger shipping labels. Monochrome output keeps consumable costs low while remaining readable for barcodes and text.

Connectivity spans Wi-Fi on the 2.4 GHz band, Bluetooth, and USB, allowing the printer to pair with Android and iOS mobile devices alongside Windows 7, Windows 10, and macOS computers. At 1.2 kg in a 232 × 145 × 148 mm blue housing, the printer sits firmly on a desk without occupying excessive space. There is no built-in display, so label design and preview are handled through the bundled NIIMBOT app or connected PC software. RFID-based tape-size detection automatically recognises compatible media and applies the correct settings, reducing manual configuration. The printer also supports mirror printing and date-and-time stamping for specialised labelling needs. Power is drawn from a 24 V / 2.5 A mains supply, confirming stationary operation rather than battery use.
