Byte
The amount of memory space to store a single character, number, letter or symbol.
One byte consists of 8 binary digits (bits). 1024 bytes is one kilobyte.
Character
In computer terminology, characters usually include letters of the alphabet, numbers,
symbols, punctuation marks, etc.
Character Code Table
Letters and symbols to be printed are sent in the form of codes from the host
computer to the printer. The codes are composed of two-digit characters such as 23
or 5B (hexadecimal). A character code table shows the correspondence between the
host computer and printer. The arrangement of characters in a table are determined
by the arrangement of the graphic set.
Character Pitch
Commonly measured as the number of characters per inch (cpi). This term is usually
applied only to fixed pitch fonts and not proportional fonts. In a fixed font, all the
characters are the same width. In a proportional font, the characters are of varying
width. See proportional spacing.
Character Set
The complete collection of characters and symbols that constitute all elements of a
set. The printer uses these characters and symbols for printing and coding after it
receives data from the printer.
Character Size
Characters are measured in point sizes where one point is 1/72”. For example, a 24-
point font contains characters 1/3” (24/72”) high, measured from the top of the tallest
character to the tails, the bottom portions of y’s and j’s that descend below the text
line.
Cleaning Page
Used to clean the fixing assembly. If black spots appear on the printed paper, feed a
cleaning page through the printer to clean the fixing roller.
(See “Cleaning the Fixing Roller,” on p.8-22)
Column Pitch
The terms column and character are often used interchangeably because 1 character
occupies one column width. Columns (characters) are measured in columns per inch
(cpi). Common settings are 10, 12, 15 cpi.
