A printhead includes a jetting module, deflection mechanism, and catcher. The jetting module includes a nozzle array extending along a length of the jetting module. The jetting module forms drops travelling along a first path from liquid jets emitted from the nozzles. The deflection mechanism causes selected liquid drops formed by the jetting module to deviate from the first path to a second path. The catcher, positioned to intercept liquid drops travelling along one of the paths, includes a drop contact surface and a liquid removal conduit connected in fluid communication by a Coanda surface including a radial surface including an array of grooves. The liquid removal conduit includes a surface that is positioned opposite and spaced apart from the radial surface such that the opposite surface of the liquid removal conduit does not contact the radial surface that includes the array of grooves.
