A server for the LPD protocol listens for requests on TCP port 515. [1] A request begins with a byte containing the request code, followed by the arguments to the request, and is terminated by an ASCII LF character. An LPD printer is identified by the IP address of the server machine and the queue name on that machine. Many different queue ...
This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
A printing protocol is a protocol for communication between client devices (computers, mobile phones, tablets, etc.) and printers (or print servers).It allows clients to submit one or more print jobs to the printer or print server, and perform tasks such as querying the status of a printer, obtaining the status of print jobs, or cancelling individual print jobs.
IPP uses TCP with port 631 as its well-known port. Products using the Internet Printing Protocol include Universal Print from Microsoft, [ 23 ] CUPS (which is part of Apple macOS and many BSD and Linux distributions and is the reference implementation for most versions of IPP [ 24 ] ), Novell iPrint , and Microsoft Windows versions starting ...
This enabled JetDirect cards to connect to almost any printer, making that printer network-capable. In 1995, the Ex plus 3 was released, with 3 parallel ports on one network interface, allowing 3 printers to share 1 network address. 1997 saw the new numbering format for both internal and external JetDirect servers.

Local port forwarding is the most common type of port forwarding. It is used to let a user connect from the local computer to another server, i.e. forward data securely from another client application running on the same computer as a Secure Shell (SSH) client. By using local port forwarding, firewalls that block certain web pages, can be ...
Turbo coding is an iterated soft-decoding scheme that combines two or more relatively simple convolutional codes and an interleaver to produce a block code that can perform to within a fraction of a decibel of the Shannon limit.
