A printer and reprinting control method do not reprint when an error accompanied by no damage to the actual printing area or print image on paper occurs so that consumables are not wasted. The printer reprints the label on which the print image was being formed when a specific error occurs if the error occurred while the inkjet head was forming the print image in the actual printing area of the label. When the non-printing area of the label is passing the printing position of the inkjet head, the print image in the actual printing area that was printed immediately before an error occurs is reprinted only if a specific error is detected, such as a paper jam error or mechanical error with the possibility of damage to the paper or label.
