GLOSSARY
resident fonts Fonts resident in the printer when shipped. Also called internal
fonts.
ROM Read Only Memory. Memory used by a micro processor that can
only be read. It cannot be rewritten.
scalable font Font scaled within the printer to any point size.
scan line Individual scan of the laser device across the width of the image.
The line of video data printed in one pass of the laser beam
across the length of the xerographic drum.
SCS SNA Character String. One logical record that is physically sent
to the printer in several parts, each of which is exactly 256 bytes
long with the exception of the last part. The SCS data stream
consists of a 1-byte printer control code followed by the data to
be printed. SCS mode is also referred to as LU1 mode. The
4220/MRP accepts the EBCDIC data stream from an SCS cluster
controller when the coax interface is installed.
short-edge binding In this style of binding, the binding margin is along the short
edge of the page, regardless of the orientation of the printed
image. See binding margin, long-edge binding.
SNA Systems Network Architecture. Defines message formats and
protocols for IBM network communications.
software Any word processing, programming, or special application
package installed in your computer system.
source Component of all communications systems, the originator of
information.
Special Features The features accessible when "Full Features" are selected under
the "Special Features" printer control panel options of the Xerox
MRP Family printers.
SSA System Status Available. A valid order or operation accepted by
a coax printer that controls printing and mode changing. In the
control unit output area (cuoa), the SSA handles mode change
using code X'00', enter send state, LU1 mode only using code
X'02', and enter receive state, LU1 mode only using code X'03'.
stacker Tray into which the printer ejects printed output. On the
4220/MRP or 4230/MRP, there are two standard output trays (the
top output tray and face-up tray) and one optional output tray
(the high-capacity stacker).
status sheet Page produced by the printer when requested through a job
command. Contains information about fonts used and errors
detected in a job.
