This section documents the implementation of the Line Printer Daemon (LPD) protocol mechanism in the Océ VarioPrint 6000 Series. This mechanism allows the Océ VarioPrint 6000 Series to communicate with the host system in order to print files.
The use of LPD implies that all files transferred from the host to the Océ VarioPrint 6000 Series are always queued on the printer in the LPD print queue, before they are processed for actual printing. The LPD protocol provides a mechanism to perform basic queue management on the LPD print queue.
Remote users may also use the LPD protocol to retrieve printer status information, which includes both printer status information and LPD print queue information.
The LPD protocol specification itself is specified in Request For Comments RFC 1179, which is an official standard from the Internet Community.
