Inkjet printers
Inkjet printers are computer printers that develop image after a command by propelling ink droplets onto printing paper. This is the most common type of printer and comes in all sizes at a varying amount for both home and professional use. Inkjet printing has been around for a number of years. It has been improved over the years and there are various types in the market giving consumers a wide range to choose from.
It uses two types of technologies. There is the continuous inkjet, which uses charged droplets of high velocity on an electrostatic field. A small amount of the ink is actually used in printing while the rest is recycled. This method results in printing at great speed. This therefore means that printing speed is not a problem.
Different From Thermal Printers
There is also the drop on demand technology, which is further divide into two, thermal and piezoelectric. Thermal inkjet printer’s technology employs passing of a current pulse through a heating element, which results in quick vaporization of ink to a bubble, increasing pressure and thereby propelling an ink droplet on the paper. Its ink is normally aqueous as it easily forms vapor bubbles. It is worth noting that the technology behind this printer is different from thermal printers.
Variation in both color quality and durability
Inkjet inks are usually aqueous and are cheap to manufacture though difficult to control on media surface. Aqueous inks are used mainly with thermal heads, as they need water to perform. There are different types of inks, solvent inks, hard solvent inks, mild solvent inks, UV curable inks and dye sublimation inks. As expected their entire outcome are varied in both color quality and durability.

Main Designs of Inkjet Head
Inkjet head are in two main designs. There is the fixed head, which is an in built head and should last as long as the printer does. Obtaining a replacement head if it gets damaged can be expensive though some cannot be replaced and this means replacing the printer itself. There is also a disposable head, which comes as part of ink cartridge that is replaceable. When this ink is exhausted the entire print head and cartridge will be replaced this deals with the issue of damaged print head.
Causes of problems in “Inkjet printing”
Inkjet printing problems can be caused by ink drying up on nozzles of the print head this is corrected by cleaning. Some printers come with a manual clean mode for the operator to manually clean the print head. Clogged inkjet nozzles may be cleaned by soaking in shallow water for a minute.
Comparison with Other Printers
In comparison to other printers, inkjet printers have several advantages they are less noisy compared to earlier printers and print finer and smoother details. In comparison to more expensive technology they have do not take a long time to warm up and printing costs per page are less, except as compared to laser printers. Disadvantages such as expensive ink and cartridges have been taken care of by third party manufacturers of the same.
