Internet Printing Protocol

The Internet Printing Protocol (IPP) is a network protocol used for distributed printing over IP networks. It allows clients to submit print jobs to networked printers, query printer capabilities, manage print jobs, and receive status updates, making it a widely adopted standard for modern network printing solutions..

Technical Details

The Internet Printing Protocol (IPP) is an advanced network printing protocol designed to support the transmission of print jobs and the management of printing services over IP-based networks. IPP builds upon the Hypertext Transfer Protocol (HTTP), leveraging its request-response model and security capabilities for reliable and extensible communication. It supports functionalities such as print job submission, job status monitoring, job manipulation (pause, cancel, restart), and querying printer capabilities.

One of the key advantages of IPP is its platform and device independence, supported by a standardized schema and MIME media types for diverse document formats. IPP enables seamless integration into heterogeneous network environments, making it suitable for use in small offices, large enterprises, and within cloud printing infrastructures. The protocol versions, such as IPP 1.1 and IPP Everywhere, have introduced additional features including automatic discovery, driverless printing, and improved security options.

IPP typically operates over TCP and UDP port 631, using HTTP encapsulation to facilitate integration with existing web infrastructure and security protocols like TLS. Its compatibility with modern networking standards has contributed to its widespread adoption as the default printing protocol in many operating systems and network printer devices.
