Port 9100 is used for printing over TCP/IP (Transmission Control Protocol/Internet Protocol) networks. It is a standard port that is supported by most network printers. When a user sends a print job to a printer, the data is sent over port 9100 to the printer’s IP address. The printer then receives the data and prints the document. This allows multiple users to print to a single printer over a network.
Ports those registered with IANA are shown as official ports. The same port number may be unofficialy used by various services or applications. The official usage are listed separately below its usage may change from time to time.
