Abstract:
1. A communication system comprising: a communication device; and a plurality of information display devices connected communicably with the communication device, wherein the communication device comprises: wherein each of the information display devices comprises: wherein in response to the error settlement starting information receiver receiving the error settlement starting information from one of the information display devices, the status storage unit of the communication device stores an in-error-settlement status representing that error settlement is being performed to fix the error represented by the error status, wherein the status transmitter of the communication device transmits the in-error-settlement status stored on the status storage unit to the information display devices, and wherein in response to the status receiver receiving the in-error-settlement status from the communication device, the display unit of each information display device displays in-error-settlement information representing that error settlement is being performed to fix the error; wherein the communication device further comprises a printing unit configured to perform a printing operation, wherein each of the information display devices further comprises a print instructor configured to issue, to the communication device, a print instruction to cause the printing unit to perform a printing operation, wherein the display device of each information display device is configured to display the operable image when status information, which is transmitted by the communication device in response to a status request issued at or after a time when the print instructor issues the print instruction, includes a print-related error status representing an error caused in the printing unit, wherein each of the information display devices further comprises a monitor configured to monitor whether the status receiver receives the in-error-settlement status until a predetermined time period elapses after receipt of the print-related error status, and wherein the display device of each information display device is configured to display the operable image when the monitor determines that the status receiver receives no in-error-settlement status until the predetermined time period elapses after receipt of the print-related error status.
