An HDD unit (12) holds a print object. A controller (11) issues to a printer unit (13) a print command of acquiring and printing the print object stored in the HDD unit (12), and has the printer unit (13) receive data in which link path information to a file to be printed is described via a connection established between the HDD unit (12) and the printer unit (13). The printer unit (13) captures and prints the print object stored in the HDD unit (12) by requesting the HDD unit (12) to send the print object which is uniquely specified with the link path information, using attribute information which is obtained by inquiring the connection status.
