4. A printer according to claim 1, further comprising analyzing means for analyzing a profile which is sent as a response in accordance with the inquiry by said inquiry means from the information terminal apparatus existing in a range where the communication can be made in accordance with said wireless data transmission system by said communication processor,

and wherein said power control means controls the power supply status of the power source which is supplied to said print processor in accordance with a result of the analysis by said analyzing means.

5. A printer according to claim 4, wherein at least a printing profile indicative of a print function is included in said profile.

6. A printer according to claim 5, wherein kind information of a printer driver stored in a form such that said information terminal apparatus can execute is included in said printing profile, and said power control means performs the power control in accordance with the kind information of said printer driver.

7. A printer according to claim 1, wherein said inquiry means has a function for recognizing the function kind and identification information of said information terminal apparatus and recognizes a change in existence of said information terminal apparatus in accordance with identification by said identification information, and said power control means shifts the power supply status from said power source to said print processor for printing said print data to a print standby mode in accordance with a result of said recognition.

8. A printer according to claim 1, wherein as a result of the inquiry by said inquiry means, if a change in existence of said information terminal apparatus having a function for transmitting data for allowing said printer to execute the printing is confirmed, said power control means shifts the power supply status from said power source to said print processor for printing said print data to a print standby mode.

9. A printer according to claim 1, wherein said print processor comprises:

a data processor for processing the print data received by said communication processor; and

a printer engine for printing and outputting the data processed by said data processor onto a recording medium.

10. A printer according to claim 9, wherein said printer engine includes a printer engine of a kind of an ink jet system or an electrophotographic system.

11. A power control method by a print control apparatus having a communication processor for making data communication with an information terminal apparatus by a predetermined wireless data transmission system and a print processor for processing print data received by said communication processor, comprising:

an inquiry step of inquiring said information terminal apparatus existing in a range where the communication can be made by said wireless data transmission system by said communication processor together with a kind of function; and

a power control step of controlling a power supply status of a power source which is supplied to said print processor in accordance with the function kind included in a response from said information terminal apparatus to the inquiry in said inquiry step.

12. A method according to claim 11, wherein as a result of the inquiry in said inquiry step, if the existence of the information terminal apparatus of the function kind having a function to transmit data for allowing a printing process to be executed is not confirmed, in said power control step, the power supply status from a power source to said print processor is shifted to a low electric power consumption mode.

13. A method according to claim 11, further comprising a monitoring step of controlling in a manner such that as a result of the inquiry in said inquiry step, if the existence of the information terminal apparatus of the kind having a function to transmit data for allowing a printing process to be executed is not confirmed, said power control means shifts a central processing unit provided for the printer itself to a sleep status, and further, even after said central processing unit is shifted to the sleep status, the inquiry in said inquiry step is executed.

14. A method according to claim 11, further comprising an analyzing step of analyzing a profile which is sent as a response in accordance with the inquiry in said inquiry step from the information terminal apparatus existing in a range where the communication can be made in accordance with said wireless data transmission system by said communication processor,

and wherein in said power control step, the power supply status of the power source which is supplied to said print processor is controlled in accordance with a result of the analysis in said analyzing step.

15. A method according to claim 14, wherein at least a printing profile indicative of a print function is included in said profile.
