Printing method and apparatus

Apparatus for triggering a printhead, the printhead having a linear array of nozzles oriented in an axis, the apparatus comprising:

• a processing module controlling the transfer of printing triggers to the printhead;
• an encoder module adapted to provide a series of pulses to the processing module, the pulses corresponding to locations of the printhead;
• wherein the processing module receives pulses from the encoder module at intervals representative of a fixed unit of spatial displacement of the printhead, and the processing unit transfers printing triggers to the printhead at one or more print intervals representative of a plurality of said fixed units of spatial displacement of the printhead.
