CUPS
CUPS (Common UNIX Printing System) is an open-source printing system that provides a standard printing interface for UNIX-like operating systems, including Linux and macOS. It manages print jobs, supports various printer drivers and protocols (like IPP), and allows network printing across different devices. Originally developed by Apple, it has become the default printing system for many Linux distributions and is widely used for centralized print server management.
Developers should learn CUPS when working on systems administration, DevOps, or embedded projects that require printing functionality on Linux or UNIX-based platforms. It is essential for setting up and managing printers in server environments, automating print tasks via APIs, and ensuring compatibility across diverse hardware in enterprise or IoT applications. Knowledge of CUPS is particularly valuable for roles involving system integration, where reliable printing services are needed.
