<P>PROBLEM TO BE SOLVED: To protect data between a driver and a printer while maintaining performance of print processing. <P>SOLUTION: When an encryption is specified to a part of print data, a client 102 determines functions supported by a printer 104. If the printer 104 is complying with the partial encryption, the client 102 encrypts the specified part, specifies the part by PDL commands or XML tags, and sends the print data to the printer. The printer 104 decrypts it and then prints it out. Meanwhile, in the case of a printer 151 which does not support a partial encryption, printing is terminated, or the print data is sent to the printer 151 after replacing the part to which the encryption is specified with a different character string. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
