Printing device, notification method, and ink ribbon cassette

A notification method comprising:

• acquiring a cumulative printed amount of a printing mechanism since an ink ribbon installed on the printing mechanism was last exchanged, the printing mechanism allowing the loop-shaped ink ribbon to be detachably installed thereto and applying an impact to the ink ribbon to transfer ink of the ink ribbon to a printing medium;
• determining whether or not the cumulative printed amount acquired has reached a predetermined first printing amount, or a second printing amount calculated based on the first printing amount;
• and
• causing an output device to output a predetermined output if it is determined that the cumulative printed amount reaches the first printing amount or the second printing amount.

An ink ribbon cassette configured to be attachable to and detachable from a printing device, the cassette comprising:

• a loop-shaped ink ribbon;
• and
• a storage section that stores a cumulative printed amount,
• wherein the printing device includes
• a printing mechanism that allows the ink ribbon cassette storing the loop-shaped ink ribbon to be detachably installed thereto, and applies an impact to the ink ribbon to transfer ink of the ink ribbon to a printing medium;
• a cumulative printed amount acquisition section that acquires a cumulative amount of printing of the printing mechanism since the ink ribbon of the ink ribbon cassette was installed on the printing mechanism, from the storage section of the ink ribbon cassette;
• a determination section that determines whether or not the cumulative printed amount acquired by the cumulative printed amount acquisition section reaches a predetermined first printing amount, or whether or not the cumulative printed amount reaches a second printing amount calculated based on the first printing amount;
• and
• an output control section that causes an output device to perform a predetermined output if the determination section determines that the cumulative printed amount reaches the first printing amount or the second printing amount.
