Abstract
In jet nozle printers in which the ink droplets are ejected individually from one or more jet nozzles for a matrix print, an orifice to produce a uniform, axially proceeding ejection of ink droplets in the nozzle direction. The jet nozzles are shaped such that the orifice is provided with a sharp edge, both in its interior region and also closely around this region, the jet nozzle brim thus formed radially around the orifice having a uniform width of not more than 20 .mu.m. The cross-section of the wall surrounding the jet nozzle orifice forms an acute-angled triangle, the apex forming the jet nozzle brim.
