When the printer is online, it is ready to receive or is receiving
commands from the computer. The printer must be online to
print.
A standard computer interface. Information is transferred
between devices over separate wires, allowing all of the bits
that make up the character to be transmitted simultaneously
(in parallel).
The position in which continuous forms paper is retracted or
“parked” on the tractors. When continuous forms paper is
loaded, it moves forward from the park position to the platen.
Memory that retains information even when power is turned
off. The printer’s permanent memory retains the default
settings specified using the printer setup mode.
Characters per horizontal inch (cpi).
A hard rubber cylinder that moves paper forward during
printing.
The printing mechanism in a dot matrix printer. The print
head consists of several print wires (pins) arranged in a matrix.
The pins strike the ribbon in the pattern needed to create the
desired character. Depending on the printer model, the print
head has either 9 or 24 pins.
A set of instructions in application software that translates
formatting choices into printer commands. When installing
the application, the user identifies the type of printer being
used so the application knows which printer driver to use.
Character spacing in which wide characters occupy more
space than do narrow characters. For example, characters such
as “W” or “M”occupy more horizontal space than do
characters such as “i” or “l.” Many soft fonts are
proportionally spaced. Sometimes designated PS, proportional
spacing is the opposite of monospacing.
