Abstract
In the case of conducting the printing through the use of a print head having nozzles disposed at a pitch being twice a predetermined pitch Pd of recording dots, control is executed to satisfy the condition that, when a minimum integer 3 forming inter times a value 3 obtained by dividing a feed quantity L corresponding to the minimum drive unit of a drive motor by the predetermined recording dot pitch Pd is divided by an integer 2 obtained by dividing a pitch Ph of the nozzles of the print head by the recording dot pitch Pd, the residue 1 is not a divisor, above 2, of the integer 2 obtained by dividing the print head nozzle pitch Ph by the recording dot pitch Pd. Whereupon, it is possible to increase the recording medium conveying speed and further to realize high-quality recording at a small recording dot pitch.
