AbstractA page-wide inkjet print head (500) is formed by assembling individual glass fiber tube sections (304), which are then sintered together drawn to thin or neck the diameter of the orifices (102), slicing the glass tube sections and depositing individual semiconductor control circuits in or approximate to the top of the glass tube sections. Ink reservoirs can supply water-based ink that flows through the glass tube sections (304) but which is held in place by capillary action. Ink is ejected by heating a semiconductor resistive element (704) deposited into one open end of the tube section so as to cause the ink to be ejected onto a print medium.
