A job processing device capable of preventing a poor communication while keeping the sufficient communication speed. The job processing device is connected to a host, which has a host interface supporting a first connection mode for communicating in a first communication speed and a second connection mode for communicating in a second communication speed being slower, and processes a job transmitted from the host. A device interface has the first and second connection modes. A connection control means changes the device interface from the second connection mode to the first connection mode when the device interface is connected to the host interface in the second connection mode and when a first operation mode for processing a job is shifted to a second operation mode being lower in power consumption. A mode control means shifts to the second operation mode from the first operation mode after changing the connection mode. |
