PRINTER

摘要

A printer includes a print unit that ejects ink droplets of at least one ink color onto the sheet, at least one roller that feeds the printed sheet, and a controller that controls the print unit to print the sheet based on image data that defines an ink provision amount of each ink color for every dot according to a print resolution. The controller detects, based on the image data, a broad solid area, and carries out a print setting change with respect to the broad solid area by making the print resolution in the image data lower and making the ink provision amount of each ink color in the image data larger according to the print resolution that is made lower. According to the printer, stains on the printed sheet can be restricted.
