A computer readable medium has computer readable instructions stored thereon. The instructions, when executed by a processor communicable with an image forming device, cause the processor to perform the steps of transmitting, to a first server connected with the processor via a network, a request for supply of an expendable item for the image forming device, acquiring a first identification for identifying the expendable item to be supplied via the first server, which first identification is transmitted by the first server in response to the request, storing the first identification acquired, onto a database, acquiring a second identification for identifying an expendable item attached to the image forming device, determining whether the second identification acquired is identical to a first identification stored on the database, and outputting first information when it is determined that the second identification is different from any first identification stored on the database.
