| 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 |
| 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. |
CPU | Central Processing Unit |
CR | Carriage Return |
CT+ | Coax/Twinax only: a model available in a previous |
| generation of the IBM Line Matrix Printer. |
CTA | Coax/Twinax/ASCII |
