Abstract:
1. A printing apparatus comprising: a reader/writer for writing and reading information onto and from a RFID tag via wireless communication; and a host computer controlling the wireless communication between the reader/writer and the RFID tag, the RFID tag being fixed to a consumable which is detachable from the printing apparatus, having a function to record information and a function to carry out wireless communication with an external device, and being capable of transmission by using both FM modulation and AM modulation, and the host computer controlling the wireless communication between the reader/writer and the RFID tag so that when information is transmitted from the RFID tag to the reader/writer, both of transmission using the FM modulation at the RFID tag and transmission using the AM modulation at the RFID tag are carried out; and a part undecodable by the reader/writer of a signal transmitted by using one of the FM modulation and the AM modulation and received by the reader/writer is interpolated with a signal transmitted by using the other of the FM modulation and the AM modulation and received by the reader/writer, and then, the signals are decoded.
