A printing system includes: a printing unit that performs printing on a sheet; a conveyance mechanism that has a printing path for guiding a sheet to a printing position of the printing unit and a reverse path for reversing the sheet passing through the printing position and guiding the sheet again to the printing position; a control unit that performs double-side printing processing depending on a plurality of methods in which maximum numbers of the sheets existing in the conveyance mechanism at the same time are different from each other; and a determination unit that determines a probability of sheet jamming occurring in the conveyance mechanism. When the determination unit determines that the jamming occurrence probability is high, the control unit selects the method in which the maximum sheet number is small, and performs the double-side printing processing in accordance with the selected method.
