Inkjet printers are very common both at private and commercial use. They are able to produce black-and-white and colored imprints. Their functioning principle is as follows: small drops of ink are sprayed on the material to create an imprint on the substrate. Inkjet devices utilize special printheads to do so. There are two head types that are currently used in printing technologies. The first one is called fixed printhead. Such head are usually built in the device. They are precise and do not require any calibrations after the purchase of a printer, however if they are broken it’s very hard to replace them (fixed heads are often inseparable from the rest of the printer). Such equipment is most commonly utilized in commercial printing machinery that requires high precision and quality. The second type is called disposable printhead, they are usually connected to an ink tank (cartridge), and if it runs out - the head is changed as well. They are more oriented for small printers used at homes, therefore the production value should maintain low, also lowering the quality of created images. It is however very easy to replace them in case they get damaged or clogged.
