ABSTRACT:
An ink ejection device used, for example, in conjunction wit a host computer or a personal computer includes a head formed with orifices from which ink droplets are ejected to print a dot image on a printing sheet. The ink supplied to the head is stored in an ink reservoir. To properly continue printing when an amount of ink remaining in the ink reservoir is small, an amount of ink remaining in the ink reservoir is detected. When the detection results indicate that less than a predetermined amount of ink remains in the ink reservoir, then printing is performed using less ink than is used during normal printing.
