what is an inkjet printer??

Answer 1

It's the most common printer for home use.

You can use different inks and different papers (depending on the printer of course) to print document, pictures, etc.

It basically sprays ink onto the paper.

There are now professional photo papers and archival inks for superior photo printing (one of their old issues).

Answer 2

It is just one type of printer that you can buy

Types of printers

1) dot matrix
oldest
like a typewriter. Uses a ribbon
noisy and slow . Used mainly now for businesses if have forms
used to be cheap and thrown away but now expensive

slow and loud. Limited graphics


2) Inkjet

most common and popular type of printer
uses a cartridge or cartridges filled with ink
the cartridge has little tiny holes in the bottom that the ink comes out of - is actually sprayed onto the paper

holes are microscopic - 2400 or 4800 per square inch
years ago the expensive inkjet printers had 300 dpi and the pictures were ok

can have color
slow
if paper gets wet the printing can bleed
cartridgea are not cheap


3) Laser printer
like a xerox machine
very fast
large cartridges
used to be mainly black and white only
now some color lasers for home use

does not bleed when paper gets wet
generally the most expensive to buy as a printer but much more economical to run in the long run

there are some other types of printers but these are the main 3 ( or even 2) that you will come across in your computer travels.
Almost all of the printers you will find in home computers are inkjet

Lastly inkjet printers are also called "bubblejet"
I think that this refers to the Canon brand of inkjet printers

Answer 3

A type of printer that sprays heated ink onto paper. An inkjet printer is less expensive to purchase than a laser printer, but the cost of consumables (ink cartridges) makes it more expensive to operate

Answer 4

Inkjet printers are a type of computer printer that operates by propelling tiny droplets of liquid ink onto paper. They are the most common type of computer printer for the general consumer due to their low cost, high quality of output, capability of printing in vivid color, and ease of use.

Answer 5

Inkjet printer is nothing is printer which print through ink. ex. If you take an HP printer you will see the Ink cartridge loaded in it. The ink flow through the head of the cartridge to print. We will refill ink for the cartridge and will not buy it because it cost much.

Answer 6

Instead of actual contact with the paper by a small pin punching against a ribbon to produce the letter sort of like a typewriter except imagine one pin doing all the work to make the letter, the ink jet printer simply sprays the ink out in very small dots to produce the image or letter.

Answer 7

Simple searches are the best. I just typed in , "what is an inkjet printer." and got this:

http://en.wikipedia.org/wiki/Inkjet_printer

Hope that helps.

Answer 8

A printer that prints by shooting ink onto the paper, as opposed to stamping it on, or burning the paper with a laser.

Answer 9

it is a printer where used during 1990s

Answer 10

In general
In the personal and small business computer market, inkjet printers currently predominate. Inkjets are usually inexpensive, quiet, and reasonably fast; and many models can produce high-quality output. Like most modern technologies, the present-day inkjet has built on the progress made by many earlier versions. Among many contributors, Epson, Hewlett-Packard and Canon can claim a substantial share of credit for the development of the modern inkjet. In the worldwide consumer market, four manufacturers account for the majority of inkjet printer sales: Canon, Hewlett-Packard, Epson, and Lexmark.

Ink jet printers use one of three main technologies: thermal, piezoelectric, and continuous.


[edit] Thermal Ink Jet
Most consumer ink jet printers (Lexmark, Hewlett-Packard, Canon) work by having a print cartridge with a series of tiny electrically heated chambers constructed by photolithography. To produce an image, the printer runs a pulse of current through the heating elements. A steam explosion in the chamber forms a bubble, which propels a droplet of ink onto the paper (hence Canon's tradename for its inkjets, Bubblejet). The ink's surface tension as well as the condensing and thus contraction of the vapour-bubble, pulls another charge of ink into the chamber through a narrow channel attached to an ink reservoir.

The ink used is usually water-soluble pigment or dye-based but the print head is produced usually at less cost than other ink jet technologies. The technology principle was discovered by Canon engineer Ichiro Endo in August 1977.

Note that this is not the same thing as a thermal printer, which produce images by heating thermal paper, as seen on some fax machines, cash register and ATM receipts, and lottery ticket printers.


[edit] Piezoelectric Ink Jet
All Epson printers and most commercial and industrial ink jet printers use a piezoelectric material in an ink-filled chamber behind each nozzle instead of a heating element. When a voltage is applied, the crystal changes shape or size, which generates a pressure pulse in the fluid forcing a droplet of ink from the nozzle. This is essentially the same mechanism as the thermal inkjet but generates the pressure pulse using a different physical principle. Piezoelectric ink jet allows a wider variety of inks than thermal or continuous ink jet but is more expensive.

InkJet with Piezoelectric is very fast and cost effective. When the Piezo crystal has an applied voltage, the crystal will shake the ink stream, causing it to break off in very small, fine droplets as the ink leaves the orifice plate hole. This droplet of ink can then be either charged or not charged, depending on whether the droplet of ink is to be printed or not.

If the droplet is to be printed onto the paper, the ink droplet is not charged. However, if the droplet is not required to be printed to the paper, it is charged with a positive bias, this way the ink droplet is then attracted to the negatively biased charge plate, the ink will hit the plate and will be vacuumed away by an ink recycle system. (This is used during the printer's automatic head-cleaning procedure, albeit consuming usable ink in the process.)

The emerging Ink jet material deposition market uses ink jet technologies, typically piezoelectric ink jet, to deposit materials on substrates.


[edit] Continuous Ink Jet
The continuous ink jet method is used commercially for marking and coding of products and packages. The first patent on the idea is from 1867, by William Thomson. The first commercial model was introduced in 1951 by Siemens. In continuous ink jet technology, a high-pressure pump directs liquid ink from a reservoir through a gunbody and a microscopic nozzle, creating a continuous stream of ink droplets. A piezoelectric crystal effects an acoustic wave as it vibrates within the gunbody and causes the stream of liquid to break into droplets at regular intervals - 64000 to 165000 drops per second may be achieved. The ink droplets are subjected to an electrostatic field created by a charging electrode as they form. The field is varied according to the degree of drop deflection desired. This results in a controlled, variable electrostatic charge on each droplet. Charged droplets are separated by one or more uncharged “guard droplets” to minimize electrostatic repulsion between neighboring droplets.

The charged droplets pass through an electrostatic field and are directed (deflected) to the receptor material (substrate) to be printed by electrostatic deflection plates, or are allowed to continue on undeflected to a collection gutter for re-use. The more highly charged droplets are deflected to a greater degree.

Continuous ink jet is one of the oldest ink jet technologies in use and is fairly mature. One of its advantages is the very high velocity (~50 m/s) of the ink droplets, which allows the ink drops to be thrown a long distance to the target. Another advantage is freedom from nozzle clogging as the jet is always in use. Volatile solvents (ketones and alcohols) can therefore be used, giving the ability of the ink to "bite" into the substrate and dry quickly. The fluid handling systems can be quite complex. Droplets are generated at ~ 64 to 165 kHz; only a few percent of the droplets are used to print; the rest are recycled.

The ink system requires active solvent regulation in order to accommodate for solvent evaporation during the time of flight (time between nozzle ejection to gutter reclamation) and from the venting process whereby air that is drawn into the gutter along with the unused drops is vented out from the reservoir. Viscosity is monitored and a solvent (or solvent blend) is added in order to counteract the described solvent loss.
