Abstract:
1. A method comprising: generating each of (i) a first signal and (ii) a second signal based at least in part on a position of a carriage, the carriage being a component of a printing device; estimating (i) a major cycle duration associated with the first signal and (ii) a first minor cycle duration associated with the second signal; estimating a position of the carriage based at least in part on the estimated major cycle duration and the estimated first minor cycle duration; and generating a plurality of print synchronization pulses based at least in part on the estimated position of the carriage, wherein a major cycle duration corresponds to a time duration between one of either the last two rising edges of the first signal or the last two falling edges of the first signal, and wherein a minor cycle duration corresponds to a time duration between one of either the last two rising edges of the first signal or the last two falling edges of the second signal.
