print-blockage-stopper

Docker-Anwendung from abadr's Repository

Übersicht

Automated maintenance prints for any network printer (especially pigment printers like Canon imagePROGRAF, Epson SureColor, HP DesignJet, etc.). Sends a small test image on a configurable schedule (default: every 3 days) to keep all ink channels flowing and prevent costly pigment clogs and cleaning cycles. Features: multi-printer support, network printer discovery, per-printer schedules, smart skip (won't print if the printer was recently used), preset test images for 4/6/8/11/12-colour printers, custom image upload, notifications (webhook, email, Home Assistant), and a modern React dashboard with dark mode.

Anforderungen

Any network printer with IPP Everywhere support (usually any modern networked printer). Especially useful for pigment printers.
