Handheld 3-inch thermal label printer

The WUQ B3S prints labels from .8 to 3 inches wide on continuous or non-continuous paper. It operates without ink, toner or carbon tape using thermal technology. The unit measures 4.5 by 4.3 by 2.4 inches and weighs 1.5 lb. It is aimed at small-business, retail and home-organising users who need portable labelling.

NIIMBOT app and 70×40 mm starter roll

The bundle includes one roll of 70×40 mm waterproof, abrasion-resistant, oil-resistant, BPA-free labels. The NIIMBOT app supplies 30-plus fonts and languages, 100-plus borders and 1500-plus symbols for text, barcodes, QR codes, images and Excel data. A built-in 2200 mAh battery gives about one week of standby per charge. The app runs on Android and iOS phones but not on iPad or other tablets.

Bluetooth-only connectivity

The printer connects solely via Bluetooth to the NIIMBOT app on a smartphone; it does not pair with tablets. For PC use a separate driver must be downloaded from the NIIMBOT website. Buyers who need Wi-Fi, USB or direct tablet printing should look elsewhere.
