proportional spacing
Text in which each alphanumeric character is given a weighted
amount of space. Such output has print-like appearance.
Proportional spacing allows more space for wide characters and
less space for narrow characters.
proportional type
Characters that vary in width.
protocol
Formal set of conventions governing the format of data and the
control of information exchange between two communication
devices.
purge
To delete data from a system.
queue
List of documents waiting to be processed.
RAM
random access memory. Storage that allows data, such as
documents, to be stored and retrieved directly by address
location without reading through any other data.
raster data
Binary data, usually consisting of dots arranged in scan lines,
according to the print order.
rasterization
Creation of a page's bit map image for printing.
read/write head
Input/output device that reads and writes data in the form of
magnetic dots on the surface of an external storage medium,
such as a magnetic disk.
record
Collection of data or words treated as a unit.
recovery
Act of overcoming a problem or error during processing.
Typically, a specialized software recovery routine gains control
and attempts to resolve the error without crashing the system.

process encompasses two functions: deleting old text and
inserting new.
report
In setting a separation boundary through the Bin Full Criteria
task, report refers to a subset of a job (a job may consist of one
or more reports).
resolution
Number of dots per unit. The LPS imaging system converts a
character from digitized data into a printed image composed of
these tiny dots. The greater the number of dots per inch, that is,
the resolution, the clearer the image that is produced.
