@roberto on Printing Kiosk

This project has been an exciting journey in transforming a manual workflow into an automated system.
I created a self-service Printing Kiosk system that runs entirely on Linux.
The system allows users to send documents via WhatsApp, which the kiosk automatically processes, converts into PDFs, lets the user configure the printing settings and sends directly to a printer via the CUPS native printing system.
The interface is a modern, web-based dashboard built with NiceGUI, configured to run in browser Kiosk mode.
The decision to rewrite the application interface from Tkinter to NiceGUI was a significant architectural shift, requiring to reimplement the layout and logic to support a web-based, Kiosk-ready experience.
If someone were to set this up, they should keep mind that it is designed to be the only process running locally so it may be demanding.
The setup script is straigntforward, users must manually configure config.json file and run the .sh file to setup all the application.

  • Tkinter version fully working, but I needed to access it remotely so switched to niceGUI
  • merged all the files (leaving only with backend.py and app.py)
  • optimized for touch screen remote control
  • modified to work on Linux as well as on Windows (using lp or SumatraPDF)
  • added a button in configuration_ui to shut down the server remotely
  • creating .sh file to install everything automatically
