GLOSSARY
XEROX 4635 LASER PRINTING SYSTEM OPERATOR GUIDE GLOSSARY-9
PDL print description language. Language used to describe printing
jobs to an LPS. PDL describes the input (type, format,
characteristics), performs the processing functions (logical
processing), and describes the output (type, format, font
selection, accounting options).
physical page Sheet of paper on which printing is done. See also edgemarking.
pica 1. Unit of measurement equal to 0.166 inch. Picas are often
used to express line measure or column width. There are about
6 picas to an inch. See also point. 2. A 10-pitch typeface. See
also elite.
pitch 1. Horizontal character spacing; 10-pitch (10 characters per inch)
spacing is called pica, and 12-pitch (12 characters per inch)
spacing is called elite. 2. The number of page images placed on
the xerographic belt during one revolution. The 4635 LPS
operates in a multi-pitch mode, allowing the mode to be
adjusted according to the width of the paper used.
pixel Acronym for picture element. Smallest addressable point of a
bit-mapped screen that can be independently assigned color and
intensity. Pixels are definable locations on a display used to form
