Printers incorporated in computer systems can be controlled by microcode instead of hardware logic circuitry. Where the printer includes a constantly moving belt or chain carrying the print characters, synchronization of the print belt or chain with compare circuitry is required for determining when to fire the hammers associated with the print positions during a print subscan where printing takes place during a series of successive print subscans. The microcode is arranged so as to minimize microcode execution time. The data to be printed is arranged so that a print buffer contains the data from all print positions which are optioned during the same subscan.
