and a braided shield. Used to connect computers to

 

input or output devices.

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. See also escape

 

sequence, SFCC, SSCC.

compatibility

The ability of one printer to accept and properly

 

process commands meant for a different printer. See

 

also emulation and protocol.

compressed

Refers to a typeface with a font width approximately

 

60% smaller than normal. Character height is not

 

changed.

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.

Central Processing Unit

CR

Carriage Return

CT+

Coax/Twinax only: a model available in a previous

 

generation of the IBM Line Matrix Printer.
