PROBLEM TO BE SOLVED: To execute high quality printing with a set side margin while preventing occurrence of a level difference even if the sheet width is narrower than that corresponding to data being printed. SOLUTION: In the recorder, a control section begins recording operation corresponding to recording data from the reference position side when the medium width based on medium width detection information is narrower than the medium width corresponding to the recording data. The control section controls a carriage drive section and a head drive section not to execute recording exceeding the width of the recording medium, controls the carriage drive section such that a nozzle array in a recording head moving to recede from the reference position located on the side closest to the reference position reaches the position of side margin determined in correspondence with the narrowed medium width, and controls the head drive section such that the recording data corresponding to an area exceeding the side margin is masked for other nozzle arrays.
