The most common output device is the monitor or VDU.
Modern monitors, where the case isn’t more than a few
centimetres deep, are usually Liquid Crystal Displays
(LCD) or Thin Film Transistors (TFT) monitors.
Laser printers
Laser printers are quite expensive to buy and run but
produce a high quality output and are quiet and fast.
Ink-jet printers
Ink-jet printers offer black and white or colour
printing with reduced levels of quality and
speed. Colour ink jet printers are cheaper to
buy than colour laser printers.
Dot matrix printers
Dot matrix printers are not so common
today. They are comparatively noisy and low
quality but are cheap to run and are used
when carbon copies or duplicates need to be
made, such as for wage slips. Also, they are
useful in dirty environments such as a
garage because they are much sturdier than
the other two types of printer
Plotters
A plotter can be used to produce high
quality, accurate, A3 size or bigger
drawings. They are usually used for
Computer Aided Design (CAD) and
Computer Aided Manufacture (CAM)
applications, such as printing out plans
for houses or car parts.
