Abstract
An ink jet printer head for printing dots on demand on a recording medium has ink flow paths formed in a substrate. The ink paths include a pressure chamber, supply path and nozzle for discharging ink droplets, the nozzle terminating in an external front face of the printer head. A piezoelectric element acting on the pressure chamber to reduce chamber volume, causes an ink droplet to be ejected. Ink flow in the paths is perpendicular to the displacement of the piezoelectric element. The front face of the printer head is adapted to contour the ink layer which forms on the front face at rapid printing rates to assure that the droplets are ejected along a line which is a linear, parallel extension of the longitudinal nozzle axis. The design principles are applicable to printer heads having single or double rows of nozzles.
