pitch. Aunit of measurement for the width of type (or a printed character), based on the number of characters that
can be set (or printed) in one linear inch; for example, 10-pitch has 10 characters-per-inch. Uniformly-spaced fonts are
measured in pitch.
point. Aunit of measurement for describing type sizes. There are 12 points to a pica, about 72 points to 1.008
inches.
power off. The action you take to remove power from the printer.
power on. The action you take to provide power to the printer.
power on configuration mode. A printer state that allows you to personalize printer parameters. Youstore these
parameters in

nonvolatile memory (NVM)

.
preprinted form. A sheet of paper (form) containing a preprinted design of constant data on which variable data can
be printed.
preventive maintenance. Maintenance specifically intended to prevent faults from occurring. Corrective maintenance
and preventive maintenance are both performed during maintenance time.
printer. Adevice that writes output data from a system onto paper or other media.
printer stand. An optional printer table available from your IBM marketing representative.
print position. The physical positions of the characters constituting a print line relative to the form.
print quality. The quality of printed output relative to existing standards and in comparison with jobs printed earlier.
print surface. The side of a form that receives the printed image.
process direction. Describes a direction that is parallel to the movement of the paper path.
program configuration mode. (1) Aprinter state that allows you to set the functions you use in your daily job. You
can save these values in

nonvolatile memory (NVM)

. (2)A diagnostic condition.
PROM. programmable read-only memory.
prop. Ashort form of the term “proportional” meaning

proportionally-spaced font

.
proportionally-spaced font. A font in which the graphic characters are contained in character cells that may vary
with the size of each graphic character and have varying character increments. This allows for even spacing between
printed characters and eliminates excess white space around narrow characters. Contrast with

constant-spaced font

.
R
RAM. random access memory.
read-only. Atype of access to data that allows it to be read but not copied, printed, or modified.
registration. In printing, refers to the relative print positions of images that are printed at different times. For
example, when you process preprinted forms, the registration is good if the new image printed by the printer aligns
correctly with the preprinted image. Print that extends beyond box edges and text that overlaps other text are
examples of poor registration.
resident font. Those font data sets that are resident within the printer.
ROM. read-only memory.
S
scrolling. Moving a display image vertically in order to view data not otherwise visible within the boundaries of the
display.
scroll keys. Keys which are used to move through menus. They are marked with arrows that indicate direction.
