INTRODUCTION
In computing, a printer is a peripheral which produces a representation
of an electronic document on physical media such as paper or
transparency film. Many printers are local peripherals connected directly
to a nearby personal computer. Individual printers are often designed to
support both local and network connected users at the same time. Some
printers can print documents stored on memory cards or from digital
cameras and scanners. Multifunction printers (MFPs) include a scanner
and can copy paper documents or send a fax; these are also called multi-
function devices (MFD), or all-in-one (AIO) printers. Most MFPs include
printing, scanning, and copying among their many features.
COLOUR INKJET PRINTERS
Inkjet printers works by propelling
droplets of ink onto the paper. The ink is
released from small movable cartridges
and if it is a colour inkjet printer there
will regularly be a black cartridge and
three separate coloured cartridges. You
can either replace the whole cartridge or
refill the cartridges with a special refill kit.
Advantages
•Inkjet printers are considerably
cheaper to buy.
•High end printers are capable of
producing good ability images when
used with special paper.
•Most models are relatively light
weight and compact so they don't
take up too much space on the desk
ADVANTAGES AND DISADVANTAGES
•Disadvantages
•Due to the cost of ink, running an
inkjet printer over time is a more
expensive than a laser printer.
•Prints emerge from the printer
slightly wet and may need time to
dry.
•Printing is slower and therefore
inkjets aren't designed for high
volume printing.
LASER PRINTER
This printer incorporates a laser beam
as a part of the image processing. Rather
than using ink a laser printer uses toner,
a dry plastic powder combined with
carbon black or colouring agents. The
consumable a part of the printer is
encased in a cartridge which needs to be
supplanted from time to time
Advantages
• Laser prints are generally very high
and very accurate.
•For high volume printing laser printers
are considerably cheaper to run.
•Printing is fast so they can cope large
volumes.
•Due to the technology used prints from
a laser printer emerge from the printer
dry to the touch.
ADVANTAGES AND DISADVANTAGES
•Disadvantages
•Buying a laser printer can be
expensive when compared to an inkjet.
•Colour laser printers are significantly
more expensive than a colour inkjet.
•Laser printers are larger and heavier
as they need to comprise the imaging
drum and laser technology.
