1. An inkjet printer system, comprising:
a repeater of a portable type that includes a carriageable storage unit and is interposed between an inkjet printer and a server,
wherein the inkjet printer and the repeater are communicated with each other over short-range wireless to transmit print related data either from the inkjet printer to the repeater or from the repeater to the inkjet printer, and the repeater and the server are communicated with each other over a communication network to transmit the print related data either from the server to the repeater or from the repeater to the server,
wherein the print related data sent from the inkjet printer to the repeater over the short-range wireless is stored in the storage unit installed in the repeater, and the print related data stored in the storage unit is sent from the repeater to the server over the communication network,
the print related data sent from the server to the repeater over the communication network is stored in the storage unit installed in the repeater, and the print related data stored in the storage unit is sent from the repeater to the inkjet printer over the short-range wireless, and
wherein each of the print related data sent from the inkjet printer to the server via the repeater and the print related data sent from the server to the inkjet printer via the repeater is encrypted with an encryption key, and
each of the server and the inkjet printer has a decryption key to decrypt the print related data which has been encrypted and sent thereto.
