Kind Code:

B2

Abstract:

An information processing device, such a Personal Computer (PC), a printing device, a print data transmission method, a printing method, a print data transmitting program, and a recording medium, are provided. The information processing device includes: an encryption key generating part (113) that generates an encryption key to be used to encrypt the print data, based on inherent information that is unique to the printing device, such as its MAC address, and is represented by a fixed value; and an encrypting part (114) that encrypts at least part of the print data, using the encryption key generated by the encryption key generating part (FIG. 3). The print data encrypted by the encrypting part are transmitted to the printing device.
