To provide a device capable of reducing the frequency of serial communication to a printer engine part and reducing the burdens of respective parts by transmitting stored status information to a second input processing means in the case of receiving the request of the status information of an output means from the second input processing means.

In the case of receiving the request of the status information of the output means from the second input processing means, the already stored status information is transmitted to the second input processing means. Relating to this device, command reception is detected by a printer serial I/F part 109, and in the case that it is the command for requesting the status information of the printer engine part 113, which one of a main body device 105 and a printer function part 102 uses the printer engine part 113 at present is judged. Then, for instance, at the time of using the printer engine part 113, the status information inside an engine information table stored in a RAM is sent out to a printer controller part 104.
