To use resources effectively and runs appropriate processes in a configuration having multiple communication units, a print control unit 201 switches a target buffer for processing data between a first receive buffer 24 that stores data received from a POS terminal 10 and a second receive buffer 26 that stores data received from a tablet terminal 13. The print control unit 201 controls the print unit 21 based on data stored in the buffer selected as the target buffer, changes the target buffer from the first receive buffer 24 to the second receive buffer 26 when control of the print unit 21 based on receipt print data stored in the first receive buffer 24 goes to a specific control state, and resets the target buffer to the first receive buffer 24 when control of the print unit based on the data stored in the second receive buffer 26 ends. |
