Abstract An inkjet printing device is arranged to employ the first set of multiple nozzle (320, 401, 403, 405) drop generators activated by a first address signal (A3 E4) and a second set of multiple nozzle drop generators activated by a second address (A3, E5) signal. The multiple nozzles of each drop generator of the first set are arranged in a predetermined geometric pattern (410), each of which encompasses at least one nozzle of a drop generator of the second set. The ink ejectors of one drop generator of the first drop generator set are arranged in subgroups, one subgroup of which shares a switched (733) power return with one subgroup of ink ejectors of one drop generator of the second drop generator set.
