The development of new technologies leads to more sophisticated models of inkjet printers, providing an even higher print quality at a lower price. Although older models still in use, uneconomic and require frequent replacement of cartridges.

Buying such a device quickly pays for itself, because it reduces the frequency replacement cartridges, which cost can be quite noticeable to the family budget. The most important element of the scalable printing technology is the unusual design of the head cartridge: ink feed into it carried out under pressure. The design consists of a pump, tank and exhaust valves, balancing. The pump operates in reverse mode, which allows to maintain the level of ink in the head at a constant level. Such mode reduces ink consumption, especially when cleaning the nozzles. In addition, it prevents the ingress of air into the printing device, leading to drying of ink. Another advantage of this head is that exclude the situation where not enough ink to print the entire document.
Before printing to the head is fed as much ink as you need to print this document. In large companies and government institutions are most commonly used laser printers. Print volumes in these institutions are large, so the use of inkjet printers there is not always appropriate. Even the most cost-effective home printers are inferior modern laser printers that are ideal for heavy duty printing. In addition, the printing speed in laser printers is much higher than that of inkjet.
