# canon-home-printer

> Free, open-source (MIT) web app that lets a family print, scan and check a home printer from any phone, anywhere. It runs on a Linux computer the printer is plugged into (built for a USB Canon PIXMA G3010 on an old laptop) and is published through Cloudflare Tunnel behind Cloudflare Access, so nothing is opened on the home router.
