Printers are
output devices which give the user the hard copies of electronic documents.
In other words, the user gets a printed copy of a document he/she has
composed, or got it from some other source, in the computer. For instance,
the user can type a letter in any 'text editor', or download a picture from
the internet; and then get a printed copy of it on a plain paper by using a
printer.
Printers vary in size, speed, sophistication, and cost. In today's world,
printers in use can be distinguished primarily into two categories- I)
Inkjet printers and 2) Laser Printers.
Inkjet printers incite ink droplets of various sizes on a plain paper to
print an image of digital quality. They employ a piezoelectric material
having ink cartridges at the back of the nozzles. It vibrates by the
pressure of electric voltage and the ink gets sprouted from the nozzles. As
the ink gets sprouted in jets with pulses of electric voltage, they are
called 'Inkjet printers'.
On the other hand, Laser printers are designed to produce prints of texts
and graphics of sublime quality. Laser printers tend to use the xerographic
technology which scans the photoreceptor across by laser beams. Due to the
implementation of the laser beams, they are called 'Laser printers'.
A comparative study
As far as speed is concerned, Laser printers have the upper hand over Inkjet
printers. Laser printers treat images and texts equally. Therefore, the
printing speed doesn't drop when it comes to printing the pictures.
Whereas, in case of Inkjet printers, each pixel has to be sprayed with ink
exclusively. Therefore, the speed tends to drop in case of Inkjet printers
when it comes to printing images of higher resolution.
Inkjet printers weigh around eleven pounds, whereas Laser printers are
almost four times heavier. The high tone cartridges are responsible for the
extra weight and space.
Laser printers employ a single high-tone cartridge for printing. Whereas,
Inkjet printers cannot suffice with just one color cartridge. Moreover, the
Inkjet cartridges tend to exhaust faster than the former.
But Inkjet printers score highly over Laser printers when the price issue
comes in. Inkjet printers are much cheaper than the Laser printers. The
average price of an Inkjet printer revolves around US$40-80. Whereas, the
average price of a Laser printer ranges around US$200-300. This is why the
Inkjet printers are still more popular to common users than Laser printers.
But since the cartridges of Inkjet printers exhaust faster than that of
Laser printers, the ultimate cost of an Inkjet printer, with cartridges,
compared to that of a Laser printer, after five years of usage, may be the
same if not more.
But common users still tend to prefer Inkjet printers ahead of Laser
printers as they don't have to invest a large sum of money at a time.
Moreover, the cost of cartridges, as well as the cost of printing per page
are much lesser and affordable in Inkjet printers. People are happy to
invest for their printers gradually, rather than bear the burden once.
