Abstract
A printer control system including a pulse signal output unit for generating a pulse signal having periods including adjacent high and low levels in a number proportional to movement amount of a carriage; a period calculation unit detecting each rising and falling edge of the pulse signal and thereupon calculating a duration of a most recent period directly prior to a detected one of the rising and falling edges; a print period calculation unit uniformly dividing each received duration by a predetermined number corresponding to the print resolution of the printer to determine a print period for each received duration; and print timing determination unit determining a plurality of first print timings based on a first print period calculated by the print period calculation unit dividing duration of a period directly prior to one of a rising and falling edge of each successive pair of rising and falling edges, and determining a plurality of second print timings based on a first print period calculated by the print period calculation unit dividing duration of a period directly prior to another of the rising and falling edge of each successive pair of rising and falling edges.
