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 yinki, okusinga ekozesebwa mu kukuba empapula z’awaka ne ofiisi; Era inkjet ya piezoelectric yeesigamiziddwa ku nkola y’okukyukakyuka kwa vvulovumenti ya ceramic plus, ekyusa butereevu vvulovumenti n’efuuka puleesa y’ebyuma, ekola ku bbugumu ly’ekisenge, tekyetaagisa kusaanuuka mu mazzi ne okisigyeni, kale si bulamu bwa kuweereza bwa mutwe gw’okukuba ebitabo buwanvu, naye era kisaanira okusengejja okw’enjawulo okukoleddwa.
