DocuPrint 180 LPS interface
The following DocuPrint 180 LPS interfaces are available to connect
a variety of input sources to the DocuPrint 180 LPS:
a variety of input sources to the DocuPrint 180 LPS:
Offline interface
The offline interface permits input from a computer-prepared
magnetic tape which is loaded onto the magnetic tape drive. The 9-
track and 18/36-track magnetic tape drives are the optional offline
interfaces available for the Xerox DocuPrint 180 LPS. Refer to the
“Xerox DocuPrint 180 LPS hardware components” chapter for more
information.

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.

DocuPrint 180 LPS system disk storage and memory
The system disks store the operating system software (OSS) as well
as the system resources (fonts, forms, and graphics) that are to be
loaded into memory for use during input processing. Refer to the
“DocuPrint 180 LPS software components” chapter for more
information on OSS.
