Appendix Chapter 12
offline
The state of the printer controller, in which it does not receive data or ex-
ecute 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 ex-
change information, in which multiple bits are transmitted at one time. Be-
cause of that, synchronization is necessary, which makes the scheme not
right for data transmission over a long distance. The most common paral-
lel 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.
PostScript printer software
The program that is used on the computer to enable printing on PostScript
printers.
printer driver
Software that enables controlling printer operations.
print job
A single batch of job for printing specified at one time from an application.
It may be directly transmitted to the printer, or temporarily stored in a print
queue.
