Patent ID: 7852501

Claim:
A printing apparatus connected to a print data generating apparatus which apparatus, the print data generating apparatus receiving a print job from an external apparatus in response to a reception of a print request from the external apparatus and generating print data based on the received print job, the printing apparatus comprising: a receiving unit configured to receive the print data generated by the print data generating apparatus, wherein the print data generating apparatus generates the print data in response to the reception of the print job in a case where the print data generating apparatus is in a standby mode; a printing unit configured to perform printing processing based on the print data received by the receiving unit; a determining unit configured to determine whether or not the print data generating apparatus is in a power saving mode incapable of receiving the print request for the printing apparatus transmitted from the external apparatus, the print request being transmitted from the external apparatus in response to an instruction for printing from a user of the external apparatus; a detecting unit configured to detect the print request for the printing apparatus which is transmitted from the external apparatus to the print data generating apparatus when the determining unit determines that the print data generating apparatus is in the power saving mode; a control-data sending unit configured to send control data for releasing the power saving mode of the print data generating apparatus to the print data generating apparatus when the detecting unit detects the print request sent from the external apparatus to the print data generating apparatus; and a notifying unit configured to notify the external apparatus of a timing suitable for the user of the external apparatus to input the instruction for printing when the detecting unit detects the print request for the printing apparatus, wherein the timing corresponds to time required for the print data generating apparatus to switch from the power saving mode to the standby mode in response to the control data sent by the control-data sending unit.
