<p>This print system comprises a characteristic storage section (24) to store the characteristic data peculiar to the engine, a CPU (25) to calculate, based on the characteristic data, the correction data for a certain clock counts after detection of the horizontal sync signal and the correction data for every time a certain time elapsed after that, a modulation data storage section (231) to receive and store the correction data, a quartz oscillator (22) to generate the basic clock, a timer (233) to monitor the time, a counter (234) to count the sync clock pulses, a modulation control section (232) which refers to the correction data upon receipt of the horizontal sync signal, determines the modulation timing according to the timer (233) or the counter (234) and provides modulation instruction to a clock generator for every modulation timing and the clock generator (235) to supply the sync clock obtained by modulation of the basic clock to the controller. <IMAGE></p> |
