ABSTRACT:
A printer enters a busy state when a device ID request from a first interface is received. In the busy state, no data is received from a second interface. When data is not received within a predetermined period of time, the busy state is released. Accordingly, a device ID request from the second interface cannot be received within the period of time from reception of the device ID request from the first interface to reception of print data from the first interface. A host connected to the second interface can display the correct printer state.
