A printer with synchronized engine/controllers is disclosed. The printer has a multi-segment printhead. Each engine/controller ( 10 ) configured to be coupled with others to drive the printhead ( 33 ). Each engine/controller ( 10 ) has an interface ( 27 ) at which to receive compressed page data. Image decoders ( 28, 88 ) decode compressed image planes image decoders to perform an expansion, in pipeline fashion, for the received compressed page data. A half-toner/compositor ( 29 ) composites respective strips of the decoded image planes and sends output to a printhead interface ( 32 ). A printhead interface ( 32 ) interfaces with the printhead. A synchronization signal generator ( 89, 90 ) may output a synchronization signal that is used to synchronize print engine/controllers. One printhead interface ( 32 ) preferably acts as master generating the synchronization signal to synchronize all the print engine/controllers to drive the printhead at any one or more of higher speed, higher input resolution, higher outlet resolution or wider format. The printhead interface comprises two LineSyncGen units, a first LineSyncGen unit providing a synchronization signal for multiple print engine/controller chips and a second LineSyncGen unit adapted to pulse a paper drive stepping motor.
