resident font Font built into the printer at the time of manufacture,
permanently available in memory. Resident fonts are also
called internal fonts.
response time
Time a system requires to respond to a command for
transferring stored data or completing the processing cycle.
restart
To resume a data processing job run from a point where it was
aborted.
restore
To bring backup copy of a program or data into service to
recover from loss or damage to the original copy.
RJE
remote job entry. In SNA, the data management section of an
operating system. RJE allows users to submit jobs to be
processed by a remotely located device.
sample tray Output tray to which sample copies, sample files, and test
patterns are delivered. This is called the top output tray on the
4235 LPS.
scan direction
For a page, this is the y–direction which is perpendicular to the
paper path. For a graphic window, the scan direction is always
horizontal, regardless of page orientation, and is considered to
be the x–direction of the window.
scan line
Line of video data printed in one pass of the laser beam across
the length of the xerographic drum.
SDLC
synchronous data link control. An IBM bit–oriented communi-
cation protocol that uses a variety of bit patterns to mark the
beginning and end of a frame.
serial interface Type or method of sending codes from computer to printer or
other device, one bit of information at a time, over a
communication line. These interfaces can function over great
distances.
sixel encoding Technique of coding raster data so that it is not mistaken for
control codes.
SNA systems network architecture. Total description of logical
structure, formats, and protocols of operation sequences for
transmitting an information unit through the communication
system.
software exerciser Software program that causes a system or component to
artificially emulate the user.
spooling Process of releasing data from main memory and storing it
temporarily until a peripheral device is ready to accept it (for
example, storing text before sending it to a printer).
status sheet
One–page printout generated by a Xerox LPS containing
information about the current interface used between the LPS
and the host computer system, the encoding it uses, fonts in
use, and errors within the current job that are detected by the
system software.
substitute escape character See user–defined key.
