Code V™ An optional QMS® emulation that allows you to
create and store forms: generate logos, bar codes,
and expanded characters; create other graphics, and
merge graphics with alphanumeric data as a
document is printed.
command An operating instruction (e.g., form feed, or FF) sent
from a computer to the printer. Also called a control
code or non-printable character. Commands are
opposed to data, which is printed.
command delimiter An ASCII character used to begin a command string
(same as SFCC). Commonly used command
delimiters are ESC (1B hex) and SOH (01 hex).
command sequence Two or more bytes that instruct the printer to perform
a special function. The first character in the
sequence is a special function control character
(SFCC). This character alerts the printer that the
string which follows is a command sequence, not a
character or graphic code.

sequence, SFCC, SSCC.
compatibility The ability of one printer to accept and properly
process commands meant for a different printer.

compressed Refers to a typeface with a font width approximately
60% smaller than normal. Character height is not

configuration Refers to the operating properties that define how the
printer responds to signals and commands received
from the host computer at the printer interface. These
properties are called configuration parameters and
are set to match the operating characteristics of the
host computer system.
controller An independent logic unit in a data processing
system that controls data paths between one or more
units of peripheral equipment.
cpi characters per inch. A measurement of monospaced
fonts indicating the horizontal character density. For
example, 10 cpi means 10 characters can be printed
in one horizontal inch.
See also pitch.
cps characters per second. A measurement of the print
speed of a serial (character) printer.
