Line Printer Remote. A network printing protocol for transmitting print jobs via port 515 to a receiving station (e.g. printer or print server) on which the LPD daemon is running. The protocol is also called Berkeley protocol – after its place of origin. The protocol consists of two components: LPR, which sends the print data, and LPD (Line Printer Deamon), which receives the print data. The LPD specification was documented in RFC 1179. In addition to the print data, the protocol transmits additional information, such as the file size and the name of the sender. It is used among other things in SAP systems, where the so-called coupling type “U” is provided for the Berkeley protocol. The BENS server can both receive and send print data via an LPR connection. The LPD Daemon is not activated on all printers by default, but it is available and can be activated. There are also printer models that do not support this protocol at all.

A unique identifier of a print job that is automatically assigned by the system that handles the print job.

IPPS is the encrypted variant of IPP. IPPS has to be initiated by the sending client. If data is sent to BENS via IPPS, then a virtual printer defined with IPP switches automatically to IPPS. If the BENS Server should send encrypted print data, then the outgoing connection on the BENS Server has to be defined as IPPS connection.

The Internet Printing Protocol (IPP) is a special Internet communication protocol for communication between client devices, mainly computers, and printers (or print servers). It allows clients to submit one or more print jobs to the printer or print server and to perform tasks such as querying the status of a printer, querying the status of print jobs, or canceling individual print jobs.

Like all IP-based protocols, IPP can run locally or over the Internet. Unlike other print protocols, IPP also supports access control, authentication and encryption, making it a much more powerful and secure print protocol than older protocols. However, encryption requires trust certificates to be installed on both the sending and receiving stations.

The BENS server can receive as well as send print data via the IPP protocol.

IPDS is the abbreviation for Intelligent Printer Data Stream. This protocol is mainly used by IBM computers (e.g. I-Series) or special software products. As a rule, one needs special printers for IPDS, which support this protocol. IPDS data can be printed with the BENS Server. For this purpose, the user needs additional modules that have to be paid for. The IPDS data are converted to Postscript or PCL5 and printed on industry standard printers.

Heartbeat is a function that checks if a device is alive. This is mostly done with the help of pings, SNMP queries and own protocols to determine the correct operation of a device.

In IT, gateway refers to the component (hardware or software) that establishes the connection between two systems. IT systems that do not know their communication partners contact their gateways directly. A gateway represents a bridge for communication between several internal or external network parts. The term gateway means that forwarded data is processed in its addressing for forwarding. This can be data in all layers of the OSI model. Depending on the layer on which the processing takes place, the corresponding system has a more specific terminology.

The abbreviation FTP stands for File Transfer Protocol and represents the network protocol used to transfer files over IP networks. FTP is used to upload files from a client to a server or download files from a server to a client. FTP can also transfer files between two servers, which is controlled by the client. FTP is at the application layer or layer 7. In addition, directories can be created and read via the file transfer protocol, and directories and files can be renamed or deleted.

FQDN is the abbreviation of “Full Qualified Domain Name”. This refers to the domain name where all nodes, starting with the root-level node, have been specified.
