Installation Planning Guide
Compartment of memory in which data is stored during transfer
from one device to another. Useful for (1) accumulating data into
blocks before storage or processing, and (2) for adjusting
differences of speed between devices, or between a device and
a communicating facility.
Optional module that moves paper from the printer to a finishing
device.
Fixed number of bits (in data processing, usually 8) operated
upon as a unit. A byte may represent a character, a machine
instruction, or some other logical unit of information.
Customer changeable unit. In the DocuPrint Model 92C, the unit
