A communication system includes a first electronic apparatus settable with first setting information for a plurality of items and a second electronic apparatus settable with second setting information for the plurality of items, and communicably connected to the first electronic apparatus. The first electronic apparatus includes first circuitry to transmit, to the second electronic apparatus, the first setting information including determination information set for each of the plurality of items to determine whether the first setting information is synchronized with the second setting information. The second electronic apparatus includes second circuitry to receive the first setting information, determine whether the first setting information is synchronized with the second setting information for each of the plurality of items based on the determination information, and reflect a value set for one of the plurality of items of the first setting information on the second setting information according to a determination.
