A computer printer is a device used for printing text or
images on hard copy stored in electronic form, generally on physical print
media like paper. Printers are designed
to support both local and network connected users simultaneously.
Nowadays, modern printers can directly interface to
electronic devices like digital cameras.
Some printers that come with non printing features are commonly known as
Multi-Functional Printers (MFP) or Multi-Function Devices (MFD). It integrates various functions of multiple
devices into one. Such types of printers
are extremely useful for small businesses and home offices.
As opposed to a traditional printer, a multi-functional
printer is a combination of devices like Printer, Scanner, Photocopier, and Fax
Machine. Likewise, there are numerous
other types of printers widely available in the market. Let's take a look at them:
Laser Printer: A laser printer works in a similar fashion as
a photocopier does. It has a roller
which is charged with electricity. A
laser beam is passed to remove the charge from portions of the roller. The parts hit by the laser are powdered by
the toner which is then transferred from the roller to the paper. Finally, the
ink is baked into the paper with the help of a heater incorporated in the
printer. People generally prefer laser
printer because of its ability to give high quality output and high speed.
Dot Matrix: It has a print head that moves across the
page. A dot matrix printer produces
characters using a cluster of pins which press an inked ribbon to the paper,
thereby creating a dot. Each character
is made in the same way. Dot Matrix printers are relatively cheaper and
durable. These qualities still attract
businesses which use them as invoice printers.
