a printing device that performs printing based on the print data received by the printing server, wherein
the terminal device stores terminal authentication printing setting information indicating a setting relating to the authentication printing and set in the terminal device,
the printing server stores change authentication printing setting information for changing the terminal authentication printing setting information,
the terminal device transmits request information requesting the change authentication printing setting information to the printing server,
the printing server transmits the change authentication printing setting information to the terminal device upon receiving the request information,
the terminal device changes the terminal authentication printing setting information based on the change authentication printing setting information received from the printing server such that an authentication for the terminal device is updated, and
in a state in which the terminal device can communicate with the printing server, when the terminal device does not receive the change authentication printing setting information from the printing server after transmitting the request information, the terminal device makes the terminal authentication printing setting information invalid.
