What is the term for either a software application or a hardware device that manages print requests?

The term for a software application or hardware device that manages print requests is a print server. A print server acts as a central hub that facilitates the process of sending print jobs from multiple clients to one or more printers. This can be in the form of a dedicated hardware device or a software application running on a computer that receives print jobs, manages them, and sends them to the appropriate printer.

Print servers are particularly useful in networked environments, as they allow multiple users to share printers without requiring a direct connection to each individual printer. They can also provide features such as spooling to queue print jobs, monitoring print jobs and printer status, and sometimes even billing users for their printing.

The other options do not fulfill the function of managing print requests. The device settings tab typically refers to options for customizing the settings of a specific device, the color management tab deals with managing color profiles and quality settings for prints, while the about tab usually provides information about the software or hardware, such as version details, but does not handle print requests.
