A printer includes a conveying path for conveying a printing medium therealong. The printer also includes a thickness detecting unit configured to detect change in thickness of the printing medium along the conveying direction, which is conveyed along the conveying path. The printer also includes a first print unit configured to print information on one surface of the printing medium whose thickness change is detected by the thickness detecting unit, and a second print unit configured to print information on another surface of the printing medium. The printer also includes a pressure mechanism configured to press the print head against the platen of each of the first and second print units, and a control unit configured to reduce pressure applied to the print head by the pressure mechanism if the thickness of the printing medium detected by the thickness detecting unit is greater than a predetermined threshold value.
