A remotely-controlled print module for use in printing labels or the like wherein differential gears are aligned on a common drive shaft and oscillatably driven to a predetermined position controllable by means of a bail shaft extending through gear slots, the gears meshing with type wheels carried on a shaft parallel to the drive shaft. The gears are loaded in one direction by means of cables and springs and, during the remotely-controlled cycle of operation, are stopped at predetermined positions by means of indexing pawls which are selectively energized through electromagnetic solenoids, the stopped position of the type wheels being compatible for striking by print hammers. The differential gears and thus the type wheels are remotely selectively controlled by computer-type commands which allow for versatility of expansion and compactness of packaging of the print module.
