Summary

A Canon SELPHY photo printer was acquired in exchange for an old 3D printer. The printer was purchased on eBay with paper and ink for less than their combined value.

Key Takeaways

The author acquired a Canon SELPHY photo printer and successfully set it up to work with Linux using CUPS and Gutenprint, enabling printing from Macs and iPhones via AirPrint.
The author developed a web app called printervention that allows users to print from older printers without needing to install software, utilizing WebUSB and an emulated Linux environment in the browser.
The web app uses the v86 emulator to run Alpine Linux with CUPS and Gutenprint, enabling compatibility with various printers by automatically detecting their make and model.
The project aims to prevent older printers from being discarded by making them accessible to a wider audience through a user-friendly web interface.
