The Open Printer is an open-source colour inkjet printer developed by Paris-based startup Open Tools to provide an alternative to proprietary consumer printing systems. Powered by a Raspberry Pi Zero W, the printer supports monochrome and colour printing while using refillable HP ink cartridges without digital restrictions. The modular design is available as either a self-assembly kit or a pre-assembled unit and connects to Windows, macOS, Linux, Android and iOS devices through the open-source CUPS print server.
The printer is constructed from standard mechanical components that can be repaired or modified, with options for wall mounting, desktop use and 3D-printed custom parts. The project is distributed under a Creative Commons BY-NC-SA 4.0 licence, allowing users to share and modify the design for non-commercial purposes. Open Tools recently demonstrated a working prototype following the project's 2025 debut.
