Printing device, data management device, message notification method, and message notification program

摘要

PROBLEM TO BE SOLVED: To provide a printer for appropriately notifying a user about that printing is impossible in a printer. SOLUTION: The printer records access information (an access source address, an access date, a usage protocol and a user name, etc.), in a database whenever access is performed from a client (S107). When the printer becomes a maintenance state or an error occurs (S109: YES), the user who performs access in the time period, etc., is extracted from the database (S111). A message that printing is impossible is transmitted to only the extracted user via a network.
