Which system allows Linux to connect to printer resources?

The correct choice is CUPS, which stands for Common Unix Printing System. CUPS is designed to manage print jobs and print queues in a Linux environment, providing a set of standards and protocols that allow the operating system to connect with printers and handle printing tasks efficiently. It supports multiple printer options and can handle printing over a network or locally, making it a widely used printing solution in Linux distributions.

CUPS utilizes various protocols, including Internet Printing Protocol (IPP), to facilitate communication between the Linux system and printers. By acting as a bridge, CUPS can manage print jobs and support a broad range of printer types, providing flexibility and convenience for users in managing their printing needs.

While LPD (Line Printer Daemon) and other systems like IPP can be components or alternatives in certain contexts, CUPS offers a more comprehensive and modern solution for print management in Linux environments. This makes it the preferred choice for connecting Linux systems to printer resources.
