Computer readable medium for outputting information, and information processor and image forming device using the same

An information processor communicable with an image forming device, comprising:

• an expendable requesting unit configured to transmit, to a first server connected with the information processor via a network, a request for supply of an expendable item for the image forming device;
• a first-identification acquiring unit configured to acquire 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;
• a first-identification storing unit configured to store the first identification acquired, onto a database;
• a second-identification acquiring unit configured to acquire a second identification for identifying an expendable item attached to the image forming device;
• a first identification determining unit configured to determine whether the second identification acquired is identical to a first identification stored on the database;
• and
• a first-information outputting unit configured to output first information when the first identification determining unit determines that the second identification is different from any first identification stored on the database.
