| 1. A method of obtaining status information showing a status of a peripheral apparatus by an information processing apparatus
in a system including the information processing apparatus and the peripheral apparatus which are mutually connected by an
interface, comprising the steps of:
allowing the peripheral apparatus to discriminate whether or not a device ID request has been made by the information processing
apparatus;
when it is determined that the device ID request has been made, allowing the peripheral apparatus to return device ID information
including the latest status information to the information processing apparatus and start a status information collecting
process for newly collecting status information after the return of the device ID information;
allowing the peripheral apparatus to measure whether or not a predetermined time has elapsed from a point of time after completion
of the latest status information collecting process; and
allowing the peripheral apparatus to return period elapse information showing whether or not the predetermined time has elapsed
on the basis of a result of the measurement to the information processing apparatus together with the device ID information.
