Appendix B
memory
The place in a computer where data can be stored and retrieved. The amount of
data stored is expressed in bytes. Memory can either be RAM or ROM.
Generally, the data stored in RAM is lost when power is turned OFF, while that in
ROM is retained even when power is turned OFF, but cannot be rewritten.
Network Interface Card (NIC)
An optional card to which network interface can be added, used for connecting a
printer to network environment.
offline
The state of the printer controller, in which it does not receive data or execute any
processing.
online
The state of the printer controller, in which it is capable of receiving data and
processing jobs.
operation system
A program or group of programs that control the functions of the computer and
its peripheral devices such as the printer.
parallel interface
A type of standards that govern the ways for two different systems to exchange
information, in which multiple bits are transmitted at one time. Because of that,
synchronization is necessary, which makes the scheme not right for data
transmission over a long distance. The most common parallel interface is
Centronics.
port
A connector through which data is exchanged between a computer and peripheral
equipment.
The parallel port permits multiple-bit data to be transmitted at one time,
commonly used in printers. The serial port is generally used to connect a modem
or other device.
portrait (paper orientation)
A vertical print orientation, in which printing is oriented so that the short edges of
a sheet of paper are on top and bottom.
PostScript font
A scalable outline font standard, widely adopted in the printing industry. By
downloading PostScript fonts in a PostScript-compatible printer, it is possible to
produce smoother letters than bit-mapped fonts can.
