raster scan. A technique of generating or recording the elements of an image by a line-by-line sweep
across the entire output medium.
resident font. Those font data sets that are resident within the printer. They usually reside on the
printer disk media (diskette or hard disk). These font sets are usually commonly used fonts. Having
them resident reduces font load time. These fonts may also be used during offline testing of the printer.
scalable font. A font whose graphic characters are represented by mathematical equations and can be
sized to different heights.
SCS. See SNA character string.
SEF. Short-edge feed. The print medium is fed into the printer short edge first.
SIMM. Single inline memory module.
simplex printing. Printing on one side of a sheet of paper. Contrast with duplex printing.
SNA character string. In SNA, a character string composed of EBCDIC controls, optionally intermixed
with end-user data, that is carried within a request/response unit.
skew. Refers to the paper going through the paper path at a slight angle. This will cause the printing
lines to not be aligned properly.
stacker. A device used to hold paper or forms that have been printed; the output device of a printer.
storage. (1) The retention of data in a storage device. (2) In word processing, a unit into which recorded
text can be entered, in which it can be retained and processed, and from which it can be retrieved. (3) A
device, or part of a device, that can retain data.
symbol set. In PCL5e, a particular assignment of hexadecimal identifiers to graphic characters.
text orientation. The position of text as a combination of print direction and baseline direction. See also
orientation.
throughput. A measure of the amount of work performed by the printer over a period of time, for
example, number of jobs per day.
token ring. A network with a ring topology that passes tokens from one attaching device to another;
for example, the IBM Token-Ring Network.
toner. (1) In a document-printing machine, image-forming material used in electrostatic processes. (2) A
supply item for the printer. The black powder used for printing images. Synonymous with dry ink.
toner density. The amount of toner dispersed over a specified area. Higher toner density yields darker
print; lower toner density produces lighter print.
trailing edge. The trailing edge of the paper is the edge of the paper that proceeds into the printer last
as it is fed from one of the paper supplies.
twinax attachment. A twinaxial attachment to the AS/400.
