Appendix F: Index / Glossary
Carriage Return (CR)
The print head is returned to the beginning
of the line. Mostly the carriage return is com-
bined with a line feed to move the print head
to the next line.
Centronics Interface
This interface is mainly used to connect com-
puters and printers. The Centronics interface
is a parallel interface. The eight bits of one
byte are transmitted simultaneously via
eight data lines. Other signal lines control the
data transmission (handshake).
Character
A character is an element from a defined
character set. Printable and non-printable
characters (control commands) are distin-
guished.
Character Set / Code Page
In a character set (= all representable charac-
ters) it is determined which characters (let-
ters, figures, special characters) are available.
Character Spacing
Fonts with set character spacing and propor-
tional fonts are distinguished.
Colour Ribbon
The colour ribbon is a continuous strip of
inked fabric which is re-inked within the car-
tridge. By the stroke of the needle the ink is
transmitted to the paper. See also »dot ma-
trix printer«.
Compatibility
Compatibility is the »harmony« of different
systems with each other. Compatible sys-
tems ensure an easy exchange of programs
or devices without major modifications.
F-6
Continuous Paper
For the printing of lists, labels or duplicates
mostly continuous paper is used which is
taken from the stack (folded in Z-shape).
Continuous paper is transported via the
spikes of the transportation unit which locks
into the lateral holes of the paper.
Control Characters
These non-printable characters of the ASCII
character set activate functions such as form
feed, line feed or carriage return. The com-
mand »Escape« activates command sequenc-
es (Escape commands).
cpi (characters per inch)
The pitch for non-proportional fonts is stated
in characters per inch.
cps (characters per second)
The printing speed is measured in characters
per second.
CR
See »Carriage Return«.
CSF
See »Cut Sheet Feeder«.
Cut Sheet
Cut sheets are fed between the platen and
different transport rollers.
Cut Sheet Feeder (CSF)
By means of a cut sheet feeder the printer can
process a stack of cut sheets without having
to re-feed every single sheet. Cut sheet feed-
ers with two feeding devices are also availa-
ble.
