Abstract
An ink-jet printing device according to the present invention includes: first and second nozzles each configured to discharge ink droplets onto a recording medium being conveyed; a calculation unit to calculate a landing position difference on the recording medium being conveyed at a conveyance speed based on first and second conveyance speeds and first and second landing position differences; and a timing control unit to control each of timings of ink droplet discharge from the first and second nozzles based on the landing position difference calculated by the calculation unit. This configuration allows appropriate correction of variance in the landing positions of ink droplets discharged from the nozzles.
