attracts applied toner particles from the toner
cartridge and transfers the particles to the paper to
produce a latent toned image. See also
electrostatic latent image.
photoconductor drum cartridge. A customer-
replaceable unit (CRU) that holds the
photoconductor. See also photoconductor drum .
photoconductor drum cover. A cover that holds
the used toner bottle in place on the
photoconductor drum cartridge.
photoconductor drum shield. The orange cover
installed on the photoconductor drum cartridge that
protects the photoconductive surface from light
when the cartridge is not installed in the printer. See
also photoconductor drum cartridge.
photodiode. A photoelectric semiconductor
device for detecting and measuring radiant energy
such as light.
photographic style. A rendering style that
preserves tonal relationships in images.
Unprintable colors are mapped to printable colors in
a way that keeps differences in lightness and
slightly sacrifices color accuracy as necessary.
photosensitive drum. A deprecated term for
photoconductor drum . See photoconductor drum.
PICT. A Macintosh graphics file format developed
by Apple Computer. PICT files consist of separate
graphics objects like lines, arcs, ovals, or
rectangles that you can independently edit, size,
move, or color.
pixel (pel). (1) The smallest distinct element of a
raster image or an image displayed on a monitor.
(2) The elementary graphical cell that constitutes an
image. (3) An element of a raster pattern or a point
where a toned area on a photoconductor can
appear.
pixels per inch (ppi). The number of pixels per
linear inch. Unlike dots, which are bilevel entities,
pixels can hold multiple levels of information. See
also dots per inch , pixel .
point. A unit of about 1/72 of an inch that is used
to measure typefaces.
point size.
See point .

port. An entry or exit boundary mechanism that
controls and synchronizes the flow of data into and
out of a processor from and to external devices
such as printers and modems.
portrait orientation. Text and images that are
printed parallel to the wider side of the paper.
Contrast with landscape orientation .
PostScript. The page-description language
developed by Adobe Systems that has become a
standard for graphic design and layout software.
PostScript files can hold both vector and raster
data, and fonts are defined with PostScript coding.
Many desktop publishing systems output PostScript
data that is interpreted by a laser printer.
PostScript level 2. The current version of
PostScript language that is used to print and display
pictures and text. PostScript level 2 includes many
enhancements to older versions of PostScript,
including improved color matching and the ability to
control printer-specific features from applications.
Power Saver. A mechanism on the printer that
sets the amount of time the printer stays idle before
changing to a lower power-consumption mode.
power-on self-test (POST). A series of electrical
and mechanical tests made by the printer. If the
tests reveal an electrical or mechanical problem,
you see an error message on the display panel.
presentation style. A rendering style that does
not match printed colors to displayed colors
precisely. Presentation rendering is used for bright
saturated colors in illustrations and graphs.
print job. See job .
print mode. The working mode in which the
printer gets information from the controlling
computer system and produces printouts. Contrast
with diagnostic mode and test mode .
print quality. The quality of printouts in relation to
existing standards and to printouts from earlier jobs.
Print queue. A storage area for the printer that
supplies a job storage, queueing, and spooling.
When you submit a job to the Print queue, the
printer gets the job immediately and stores it on the
printer's hard disk. Jobs in the Print queue print in
the order the printer receives them. You can use
the IBM Color Spooler to move jobs from the Print
