Thermal Printer
Thermal Printer Components
We provide you a vintage-feeling but practical expansion module - the thermal printer. It uses a standard 58mm thermal paper and has an easy-to-load design. With the open-source standard CUPS print driver provided by the clockworkOS, you can print various monochrome fonts, symbols, graphics, and even complete A4 size output through collage. You can also buy thermal printing paper* with adhesive backing or different colors, plan your work and life, mark key points, and give notes, anytime, anywhere. The sturdy “input tray” provides a storage function, allowing you to carry it freely.
The CUPS print driver is released under the GPL v3 license, and you can find it on our GitHub.
- Safety reminder: It is recommended to use BPA-free thermal papers.
Paper Dimensions
The printer uses standard 58 mm thermal paper. Based on the published 3D models, the maximum diameter for a roll is about 42mm.
