Taming System with Python: A Sysadmin perspective
summary
Daily printing problem becomes a tiny client/server: Linux laptop POSTs files, Redis stores metadata and acts as Redis as queue server, a Flask web front end spawns a daemon worker that pulls jobs, calls the Windows API to run shell print commands and fetches files from a Windows share. Implementation uses Python queues, Redis, Flask and Win32 API, runs on OpenBSD test client and successfully prints PDFs without writing a driver.
