To permit a plurality of medium processors to be appropriately used by simple control.
A printer 500 has a roll paper printing section 530, a first interface 510 receiving a command sent from a POS terminal 20, a second interface 515 transmitting the received command to a complex machine 400, and a control section 550 controlling the roll paper printing section 530 to make it perform processing on the basis of the received command and controlling the second interface 515 to make it transmit the received command to the complex machine 400. The control section 550 makes the roll paper printing section 530 carry out a command when the received command is a command to be carried out by the roll paper printing section 530, and makes the second interface 515 transmit the command to the complex machine 400 when the command is other than the command to be carried out by the roll paper printing section 530.
