PURPOSE: To shorten printing time and to attempt to improve print properties by a system wherein the first color is printed by feeding a recording paper in one direction and then, the second color is printed by feeding the recording paper in the reverse direction.

CONSTITUTION: After a yellow printing is performed on a recording paper 4, an ink sheet 13 is ordinarily carried and positioning of the head of a mazenta ink layer 22 is performed. Then, while a recording paper 4 and the sheet 13 are reversely carried in the reversely carrying direction shown by the arrow mark C, the mazenta printing is performed on the recording paper 4. Then, the sheet is ordinarily carried and positioning of the head of a cyan ink layer is performed and the cyan printing is performed while the recording paper 4 and the sheet 13 are ordinarily carried in the arrow mark B direction. After printing of three colors are performed like this on the recording paper 4, the recording paper 13 is ordinarily carried by means of a pair of paper discharging rollers 11 and is discharged in a paper discharging case 3. As the mazenta printing is performed while the recording paper 4 is reversely carried twice like this, printing time is surely shortened. In addition, as it becomes unnecessary to perform largely reverse carrying of the printed recording paper 4 for positioning of the head, positional deviation of three colors can be prevented from occurrence and printing properties can be improved.
