Abstract
An ink-jet printer includes an ink tank for storing ink, a print head for ejecting the ink supplied from the ink tank to print an image on a paper sheet moved relatively to the print head, an ink-amount sensing section for sensing that ink remaining in the ink tank is decreased to less than a reference amount to generate a sense signal, and a print control circuit for driving the print head such that images are printed on the number of paper sheets ordered by each print job except in a state where the sense signal is generated by the ink-amount sensing section. In particular, the print control circuit is arranged to continue a print job being executed at a time when the sense signal is generated by the ink-amount sensing section.
