Abstract:
1. A printer comprising: an inkjet head including a plurality of nozzles for discharging ink; a holding member which holds a print medium to be printed on; a moving mechanism which moves at least one of the holding member and the inkjet head so as to move the inkjet head relative to the holding member in a main scanning direction and a sub scanning direction for printing by the inkjet head on the print medium; a flushing printing data storage unit which stores multiple types of flushing printing data for the flushing printing; and a print control unit, comprising a selection unit which lets a user select a desired type of flushing printing data from the multiple types of flushing printing data stored in the flushing printing data storage unit, and which controls the inkjet head and the moving mechanism so as to execute flushing printing on the print medium for preventing clogging of the nozzles while moving the inkjet head relative to the holding member in a first printing direction in the main scanning direction and to execute pattern printing on the print medium according to pattern printing data while moving the inkjet head relative to the holding member in a second printing direction in the main scanning direction, wherein the flushing printing is executed at a first dot density throughout a pattern printing area, and the pattern printing is executed at a second dot density, and the first dot density is lower than the second dot density.
