ABSTRACT:
A recording head has a plurality of nozzle opening trains for respectively ejecting different inks having different drying indices, and corresponding cap members disposed outside a printing region. Clogging of ink is efficiently prevented by disposing the nozzle opening train having ink with a higher drying index closer to the cap members than the nozzle opening train with a lower drying index. Timers detect times for idle ejection. When only the nozzle opening train with the higher drying index must perform an idle ejection, a controller positions it opposite the cap member nearest the printing area; the other nozzle opening train is thus not, at that time, positioned opposite a cap member.
