If you own a NIIMBOT label printer—such as the popular D11, D110, or B21—you are likely familiar with the official mobile app. It works well for basic tasks like printing address labels, price tags, or kitchen storage stickers. However, for developers, makers, and small business owners, the official software often feels limiting. It lacks batch processing, API access, desktop controls, and open-source customization.

Niimpy is a pure Python library that reverse-engineers the Bluetooth communication protocol of NIIMBOT printers. It supports the D11, D110, B21, and several generic thermal label printers.
