According to a print controller of this embodiment, when a part of print data is specified to be encrypted, a client 102 determines functions supported by a printer 104. If the printer 104 is capable of handling partial encryption, the client 102 encrypts the specified portion, specifies the portion 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 partially encrypted printing, printing is terminated, or the print data is sent to the printer 151 after replacing the portion specified to be encrypted with a different character string.
