Abstract:
1. An image forming apparatus capable of communicating with an information processing apparatus, comprising: a reception unit adapted to receive from the information processing apparatus encrypted data formed by encrypting data including at least PDL (Page Description Language) data; a first decryption unit adapted to decrypt the encrypted data received by the reception unit and acquire decrypted PDL data which is included in the decrypted data; a conversion unit adapted to convert the decrypted PDL data by the decryption unit into raster image data, an encryption unit adapted to encrypt the raster image data converted by the conversion unit using first key information; a storage unit adapted to store the encrypted raster image data encrypted by the encryption unit at least until a user instruction for performing a printing processing is received; a second decryption unit adapted to decrypt the encrypted raster image data stored in the storage unit using the first key information; a printing unit adapted to print an image based on the raster image data decrypted by the second decryption unit; and a control unit adapted to perform processing operations before a user instruction for performing printing processing is received, thereby increasing the printing-response time once the user instruction is received, by,
