    • A printing method is provided for printing on a medium with a color material by a printer including a cartridge accommodating section that removably accommodates a cartridge to which an advance payment information storage section for storing therein advance payment information is attached and which contains the color material. The printing method includes the steps of: reading/writing the advance payment information to/from the advance payment information storage section of the cartridge accommodated in the cartridge accommodating section; outputting a print driving signal for controlling to print; printing by using the color material in the cartridge based on the print driving signal outputted by the print controlling step; acquiring the print driving signal outputted by the print controlling step and converting the print driving signal to accounting information; and settling the advance payment information read by the advance payment information reading/writing step by the accounting information converted by the print driving signal converting step.

    • A printer generates a public key with a passphrase containing at least printer position information and a random number by a public key cryptography, and holds this random number. A print client previously acquires the public key from the printer. When transmitting print data to the printer, the print client encrypts the print data in advance with the acquired public key and transmits the encrypted print data as print transmitting data. The printer which has received the print transmitting data generates a private key with a passphrase containing at least printer position information and the held random number by the public key cryptography. The printer then decrypts the received print transmitting data with the private key. Consequently, the security of the print data transmitted from the print client to the printer via a network is ensured.
    • 打印机生成具有至少包含打印机位置信息和通过公共密钥加密的随机数的密码的公钥,并保存该随机数。 打印客户端以前从打印机获取公钥。 当将打印数据发送到打印机时,打印客户端用所获取的公钥预先加密打印数据,并将加密的打印数据作为打印发送数据发送。 已经接收到打印发送数据的打印机生成具有至少包含打印机位置信息和通过公钥密码学保存的随机数的密码的私钥。 然后打印机用私钥对接收到的打印发送数据进行解密。 因此,确保了从打印客户端通过网络传送到打印机的打印数据的安全性。
