C. Glossary
ASCll:
ASCll is the abbreviation for "American
Standard Code for Information Interchange".
The printer instructions used in this manual are
entered in ASCll characters. Decimal or
hexadecimal characters may, however, also be
used.
Barcode:
Information about a medium is converted into
a one-line barcode that is independent of both
language and symbols. A barcode is easy to
create and can be easily read by simple opto-
electronic devices. It is printed on the medium
in addition to written information.
Baud rate:
The baud rate is the speed at which data is
transmitted between the computer and printer
on the serial interface. The computer and
printer must have the same baud rate. This
can be between 1200 and 9600 baud,
depending on the computer used. The baud
rate is defined only for a serial interface.
Bit:
Binary digit. As the smallest unit of digital
information, a bit can represent only two
positions, "1" or "0".
Bitmap:
The bitmap represents a collection of dots in
the form of graphics or text in output
equipment (printers, monitors).
Buffer:
The buffer is a memory area in the printer.
Data destined for input or output is stored
there until it is ready for further processing.
Byte:
A memory unit consisting of 8 bits.
Cartridge:
The cartridge contains the ink for printing.
When it is used up, the empty cartridge is
replaced by a new one.
Characters:
These consist of letters, numbers and symbols
that can be printed out.
Character height:
This refers to the height of a printed upper-
case character. The dot size is measured in
pica points. A point is 1/72 of an inch.
Character sets:
A character set is defined according to the
specific application and is usually a collection
of letters, numbers, lines and symbols within a
font. However, character sets may also consist
purely of symbols.
Character spacing:
All fonts have either a constant or a variable
character spacing. In a font with constant
character spacing, all characters have the
same spatial width irrespective of their size. In
proportional fonts, the spatial width depends
on the width of each respective character.
Configuration:
A configuration allows you to make certain
printer settings. You may set up several
configurations and save each of them under its
own configuration name.
Control code:
See Printer instructions
Controls:
The controls comprise the keyboard and the
display. They are used to make the internal
settings on the printer.
CPl:
Characters Per Inch: This is the unit of mea-
surement for the pitch.
Data transfer:
This refers to the transfer of information
between computer and printer.
Default configuration:
The printer is programmed with standard
settings prior to delivery. These settings are
stored in the configuration "0" and remain
active until another configuration number is
selected and new settings are made.
Dot size:
The dot size is measured in pica points. One
point is 1/72 of an inch.
DPl:
Dots Per Inch: This is the unit of measurement
for the resolution. The more dots, the higher
the resolution.
Drivers:
