PRINTING DEVICE AND PRINTING METHOD

摘要

A printing device includes a required ink amount acquisition part, an ejectable amount acquisition part, and a division printing control part. The required ink amount acquisition part is configured to determine a required ink amount based on print data of a bandwidth over which ink is ejected by driving an ink head in a main scanning direction. The ejectable amount acquisition part is configured to determine an ejectable amount based on a residual amount in an ink cartridge. The division printing control part is configured to determine whether a printing for the bandwidth is performed by one time of a main scanning operation, or the printing is performed by dividing into multiple main scanning operations based on the required ink amount and the ejectable amount, and to perform the printing in accordance with the determination.

1. A printing device having a print head configured and arranged to eject ink supplied from an ink cartridge, the print head being reciprocally drivable in a main scanning direction, which intersects a paper feed direction, with respect to a print medium, and the print medium being sequentially drivable in a sub-scanning direction, which is the paper feed direction, the printing device comprising:
a required ink amount acquisition part configured to determine a required ink amount based on print data of a bandwidth over which the ink is ejected by driving the ink head in the main scanning direction; an ejectable amount acquisition part configured to determine an ejectable amount based on a residual amount in the ink cartridge; and a division printing control part configured to determine whether a printing for the bandwidth is performed by one time of a main scanning operation, or the printing is performed by dividing into multiple main scanning operations based on the required ink amount and the ejectable amount, and to perform the printing in accordance with the determination.
