Online The channel-attached host computer input is received by the
DocuPrint 180 LPS online interface. In an online environment, the
system controller is physically wired to the host computer. The host
computer "thinks" it is communicating with an IBM 3211 line printer
and an IBM 3811 printing system controller, or an IBM 4245 line
printer.
DDI interface The Dynamic Document Interface (DDI) enables communication
between a Xerox DocuPrint 180 LPS and network via a shared disk
mechanism over a SCSI bus. Refer to the Xerox Dynamic Document
Interface Operator Guide for information regarding the DDI.
Offline Magnetic tape input (9- or 18/36-track) is received by the offline
interface. The LPS Tape Formats Manua l describes the tape format
and encryption schemes which a Xerox LPS recognizes.
