Abstract
A continuous printing apparatus includes a printhead including a first row of nozzles and a second row of nozzles. The first row of nozzles are spaced apart from the second row of nozzles by a distance A. The nozzles of the first row and the nozzles of the second row have a nozzle to nozzle spacing B when compared to each other. The apparatus includes a plurality of charging electrodes with one of the plurality of charging electrodes corresponding to each of the nozzles of the first row and the second row, wherein A≧B/2. The apparatus can include a first deflection electrode and a second deflection electrode with the first deflection electrode being spaced apart from the second deflection electrode by a distance D, wherein D>A.
