plotter. Anoutput unit that presents data in the form
of a two-dimensional graphic representation.
point. In printing, a unit of about 1/72 of an inch
used in measuring typographical material. Each pica
contains 12 points.
point size. The height of a font in points.
postprocessing option. Ahardware device that
attaches to the output side of a printer; for example, an
envelope stuffer,binder, or stapler.
PostScript. Apage description language with
interactive graphics capabilities that was developed by
Adobe Systems, Incorporated.
preprinted form. Asheet of paper that contains a
preprinted design of constant data. Variabledata can be
merged on such a form.
preprocessing option. Ahardware device that attaches
to the input side of a printer; for example, a paper-roll
feed or multiple input bins.
print data set. Synonym for print file.
print definition. Contains instructions for
transforming simple SCS print output to advanced AFP
output. Aprint definition includes the specifications for
remapping existing print data, defining and creating
different page formats and copies, and adding
document elements such as overlays, images, fonts, bar
codes, and constants.
print file. Afile created by an application program
that contains the actual information to be printed and
some of the data that controls the format of the
printing. Print files can contain MO:DCA-P data, line
data, or a combination of MO:DCA-P and line data.
print job. The data to be printed that is submitted to
Print Services Facility by the user.
Print Services Facility (PSF). An IBM licensed
program that produces printer commands from the
data sent to it.
printer driver. Aprogram that passes commands and
resources with a data stream fromthe system spool to
tell the printer how to print the page.
proportionally spaced font. Afont in which the
characters have different character increments. Graphic
character widths vary with the size of each graphic
character.This allows for even spacing between printed
characters and eliminates excess space around narrow
characters, such as the letter i. Contract with uniformly
spaced font.
R
raster font. (1) Afont created by a series of pels
(picture elements) arranged in scan lines to form an
image. (2) Afont in which the characters are defined
directly by the raster bit map.
raster graphics. Computer graphics in which a display
image is composed of an array of picture elements
(pels) arranged in rows and columns. Contrast with
vector graphics.
raster pattern. Aseries of picture elements (pels) in
scan lines to form an image. See also page segment.
record. Acollection of related data or words, treated
as a unit; for example, in stock control, each invoice
could constitute one record.
remote printer. Adevice that prints in a location away
from the centralized data processing center.
resource. Acollection of printing instructions and
sometimes data to be printed consisting entirely of
structured fields.A resource can be stored as a member
of a library and can be called for by Print Services
Facility when needed. Coded fonts, font character sets,
code pages, page segments, overlays, form definitions,
and page definitions are all resources.
resource library. (1)A collection of related files. (2) A
place to store resources such as form definitions, page
definitions, page segments, fonts, and overlays.
rotation. The number of degrees a character is rotated
relative to the print direction. One of four directions
that define the orientation of text relative to a sheet,
page, overlay,text block, or page segment.
S
scanner. Adevice that examines a spatial pattern one
part after another and generates analog or digital
signals corresponding to the pattern. Scanners are often
used in mark sensing, pattern recognition, or character
recognition.
SCS. See SNAcharacter string (SCS)
segment. See page segment.
simplex printing. Printing on only one side of the
paper.Contrast with duplex printing.
SNA. Systems Network Architecture(SNA)
SNA character string (SCS). In SNA, a data stream
composed of EBCDIC controls, optionally intermixed
with end-user data, that is carried within a
request/response unit.
