In order to reduce power consumption and shorten the waiting time until printing, the PC, controlling the MFP that is maintained in a sleep mode instead of being switched to a standby mode when a print job having a printing method set to confidential printing is received while it is in the sleep mode, includes a setting accepting portion to accept setting for printing, a job generating portion to generate a print job based on the accepted setting, a job transmitting portion to transmit the generated print job to the MFP, and a command transmitting portion to transmit a wake-up command to switch the MFP to the standby mode when the setting of the confidential printing as the printing method is accepted and when there is a wake-up instruction.
