How Inkjet Printers Work

[david09]

Hello Friends,

I found that there have been lots of companies in the market who, provide various series in Inkjet printers technologies. Here is list of some of them - Inkjet Canon Printers, Inkjet Compaq Printers, Inkjet Epson Printers, Inkjet Hewlett Packard Printers, Inkjet Kodak Printers, etc...

I want to know how Inkjet Printers work? Companies are using their own strategy which is different than other companies or it will be same for all? Which company provide a good service in Inkjert Printer?

Thanks for your help in advance...

Inkjet printing, like laser printing, is a non-impact process. Ink is emitted from nozzles while they pass over media. The operation of an inkjet printer is easy to visualize: liquid ink in various colors being squirted onto paper and other media, like plastic film and canvas, to build an image. A print head scans the page in horizontal strips, using the printer's motor assembly to move it from left to right and back again, while the paper is rolled up in vertical steps, again by the printer. A strip (or row) of the image is printed, then the paper moves on, ready for the next strip. To speed things up, the print head doesn’t print just a single row of pixels in each pass, but a vertical row of pixels at a time.

For most inkjet printers, the print head takes about half a second to print the strip across a page. On a typical 8 1/2"-wide page, the print head operating at 300 dpi deposits at least 2,475 dots across the page. This translates into an average response time of about 1/5000th of a second. Quite a technological feat! In the future, however, advances will allow for larger print heads with more nozzles firing at faster frequencies, delivering native resolutions of up to 1200dpi and print speeds approaching those of current color laser printers (3 to 4 pages per minute in color, 12 to 14ppm in monochrome). In other words, declining costs for improving technology.

At the most basic level, what the printer does is place small drops of ink onto the paper. Inkjet printers are considered a type of non impact printer, as opposed to dot matrix, since the ink is transfered to the paper by way of nozzles. These nozzles spray the ink directly onto the paper.

There are two different methods that inkjet printers often employ: the thermal bubble and the piezoelectric. The first lends its name to the bubblejet type of printer, and handles things quite differently from the piezoelectric method.

With the thermal bubble, or bubblejet, resistors create heat, which then creates a bubble in the ink. The bubble expands and forces ink out from the nozzle. Eventually, it will collapse, drawing more ink into the cartridge. On average, a bubblejet printer will have a range of three hundred to six hundred nozzles.With the thermal bubble, or bubblejet, resistors create heat, which then creates a bubble in the ink. The bubble expands and forces ink out from the nozzle. Eventually, it will collapse, drawing more ink into the cartridge.

The piezoelectric utilizes small crystals in the nozzles which will vibrate under the influence of an electric current; this in turn pushes ink out and draws more ink into the cartridge. The drops of ink that come from the piezoelectric type printer are significantly smaller than those of the bubblejet printers, allowing for greater control over the image quality. This method is patented by Epson, which accounts for its smaller market penetration; the thermal bubble method is used by the majority of printer manufacturers.

One of the most popular and affordable printers available today is the inkjet printer. But how exactly do these common printers work?

These printers were first mass produced in the 1980s, but it took until the 90s for the price to drop to a point that the average consumer would take notice. Since then, inkjet printers have been used in the home, the office, and even in the commercial printing environment.

The low cost and relatively high quality of prints that are offered by the inkjet printer is suitable for most day to day tasks; unfortunately, if you do a great deal of printing, the price of cartridges might drive you out of house and home! Well maybe not that bad, but keep in mind that if you do a great deal of heavy duty printing, that the ink cartridges cannot hold that much ink, and you might end up buying many times the cost of your printer in ink.

Hello Friends,

Thanks for your valuable reply. I am really very thankful to all of you for your help.

An inkjet printer is any printer that places extremely small droplets of ink onto paper to create an image.They are the best in their work.Cheap in price and good in quality.
