Openprinter is an open-source, repairable inkjet printer designed for makers, artists, and anyone tired of throwaway hardware. Built with standard mechanical components and modular parts, it’s easy to assemble, modify, and repair. You can print on standard sheets or paper rolls and choose between black or color cartridges, refillable at your convenience.

This project aims to reclaim our everyday tools. As such, it features no proprietary drivers, no cartridge DRM that locks you to a single vendor and is designed to never become obsolete. The Openprinter is built for longevity and customizability, ensuring that it remains fully under your control.

Take Back Your Printer

Thanks to its open-source, standard components, Openprinter can be assembled, customized, and repaired to extend its life. You can easily maintain it and refill cartridges with ink, and its flexible design can adapt to your workspace, working when installed on a wall or placed on a desktop.

Openprinter adapts to your needs, not the other way around. With Openprinter, you can choose between standard sheets or a paper roll, giving you an incredible degree of flexibility. Create not only standard documents, but also banners or strips. Unleash your creativity without constraints thanks to its ingenious integrated cutter:
