Inkjet technology is divided into continuous inkjet and on-demand inkjet (DOD), the former is currently only used in the digital printing machine Kodak,most inkjet printers in the market are on-demand inkjet technology, on-demand inkjet is divided into piezoelectric and thermal foaming, thermal foaming print head is cheap, high precision, but the drawback is obviously: life is short, only for water based encre, oyo basalelaka mingi na imprimerie ya papier na ndako mpe na bureau; Mpe jet d’encre piezoélectrique ezali fondés na principe ya déformation ya tension céramique plus, ebongoli directement tension na pression mécanique, kosala na température ambiante, ezali na besoin te ya ko dissoudre na mayi na oxygène, donc kaka te vie ya service ya tête d’impression ezali molayi, kasi ezali mpe malamu mpo na encre oyo esalemi na solvant ndenge na ndenge.
