Patent Images
1. A system having an imaging apparatus which outputs a sensed image and a printing apparatus connected to the imaging apparatus via an interface,the imaging apparatus comprising:
- issuing means for issuing a print request command containing a parameter for designating a print mode to the printing apparatus connected to the imaging apparatus via the interface;
transmission means for transmitting image data corresponding to the print mode; and
means for transmitting, to the printing apparatus, the print request command in which the parameter for designating the print mode is changed to invalid data to instruct printing of the image data transmitted by the transmission means, andthe printing apparatus comprising;
data request means for transmitting a data request to the imaging apparatus in accordance with the print request command;
reception means for receiving the image data transmitted from the imaging apparatus in accordance with the data request from said data request means; and
print control means for printing the image data in accordance with reception of the image data by said reception means and the print mode, and so controlling the printing apparatus so as to print unprinted image data in response to receiving the print request command in which the parameter is changed to invalid data.

Abstract
An imaging apparatus capable of outputting a sensed image to a printing apparatus issues a print request command containing a parameter for designating a print mode to a PD printer apparatus connected via an interface. The imaging apparatus transmits image data corresponding to the print mode on the basis of a data request from the PD printer apparatus. The imaging apparatus transmits, to the PD printer apparatus, the print request command in which the parameter is changed to invalid data, thereby designating printing of the transmitted image data.

4. An imaging apparatus capable of outputting a sensed image to a printing apparatus, comprising:
-
issuing means for issuing a print request command containing a parameter for designating a print mode to the printing apparatus connected to the imaging apparatus via an interface; transmission means for transmitting image data on the basis of a data request from the printing apparatus; and means for transmitting, after the print request command containing a valid parameter for designating the print mode is transmitted to the printing apparatus, the print request command in which the parameter is changed to invalid data, in order to designate the start of printing of unprinted image data that is transmitted by said transmission means, in a case that printing of the image data transmitted by said transmission means is designated. - View Dependent Claims (5, 6)

7. A control method of an imaging apparatus capable of outputting a sensed image to a printing apparatus, the method comprising:
-
an issuing step of issuing a print request command containing a parameter for designating a print mode to the printing apparatus connected to the imaging apparatus via an interface; a transmission step of transmitting image data on the basis of a data request from the printing apparatus; and a step of transmitting, after the print request command containing a valid parameter for designating the print mode is transmitted to the printing apparatus, the print request command in which the parameter is changed to invalid data in order to designate the start of printing of unprinted image data that is transmitted in said transmission step, in a case that printing of the image data transmitted in said transmission step is designated. - View Dependent Claims (8, 9, 10, 11)

12. A printing apparatus connected via an interface to an imaging apparatus for outputting a sensed image, comprising:
-
data request means for transmitting a data request to the imaging apparatus in accordance with a print request command; reception means for receiving image data transmitted from the imaging apparatus in accordance with the data request from said data request means; and print control means for printing image data received by said reception means, in a case that the number of items of image data received by said reception means has reached a defined number of image data corresponding to the print mode that is designated by a valid parameter of the print request command, and controlling said printing apparatus so as to print unprinted image data received by said reception means, in response to the print request command in which the parameter is changed to invalid data. - View Dependent Claims (13)
