About HOPA Printer
This project was designed for a restaurant in Israel to enhance their kitchen and order management workflow. With the Raspberry Pi as the central hub, the system fetches incoming orders via Wi-Fi from a remote server and routes them to the correct printer on a closed LAN. The Raspberry Pi auto-detects and maps thermal printers to their designated stations, ensuring efficient distribution of orders and enabling remote diagnostics through a central dashboard.
The implementation incorporates MQTT and Message Queue protocols for reliable ticket routing based on order types. The system supports OTA (Over-the-Air) updates to enable seamless software upgrades, and utilizes Node.js and Puppeteer for rendering HTML-based receipts into printable image formats.
By maintaining efficient communication between devices and ensuring scalability, HOPA Printer provides a reliable, automated, and intelligent receipt printing infrastructure for restaurant operations.
