<P>PROBLEM TO BE SOLVED: To provide a printer and a print system in which secrecy can be kept surely even when printing is not completed normally. <P>SOLUTION: The print system (1) comprises a printer (10) and a plurality of personal computers (20). Each personal computer can transmit data to be printed as it is or can transmit the data while ciphering. When ciphered data is provided, the printer requests the personal computer to transmit a decryption key and decrypts the data using the received decryption key before the data is printed. When printing of decrypted data is not completed normally, the printer erases the decrypted data and the decryption key and then transmits a notice of error to the computer. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
