Abstract

According to a print system, a printer supplies function information of the printer to a DSC based on a communication link between the DSC and the printer, and the DSC establishes a UI based on the supplied function information to display it on the DSC. The DSC converts image data of an image file according to print conditions set up based on the UI and the function information of the printer and transmits the converted image file to the printer.

Claims

1. A printing system having an image supply device and a printer, for printing an image with the printer based on image data supplied from the image supply device, wherein:

the image supply device comprises;

means for obtaining function information of the printer according to a communication between the image supply device and the printer;

means for establishing a UI based on the function information and displaying the UI;

conversion means for converting image data of an image file to be printed according to print conditions set up using the UI and the function information; and

transmission means for transmitting the image data converted by said conversion means to the printer in response to a data request from the printer,

wherein the printer prints an image based on the image data transmitted by said transmission means in response to the data request.

2. The system according to claim 1, wherein the conversion by said conversion means includes at least one of resizing, color conversion and rotation of the image data.

3. The system according to claim 1, wherein said conversion means starts conversion of the image data of the image file in response to a request for information of an image file from the printer.

4. An image supply device for directly communicating with a printer and supplying image data to the printer, comprising:

means for obtaining function information of the printer based on a communication link between the image supply device and the printer;

display means for establishing a UI based on the function information and displaying the UI;

conversion means for converting image data of an image file to be printed according to print conditions set up based on the UI and the function information; and

transmission means for transmitting the image data converted by said conversion means to the printer in response to a data request from the printer.

5. The image supply device according to claim 4, wherein the conversion by said conversion means includes at least one of resizing, color conversion and rotation of the image data.

6. The image supply device according to claim 4, wherein said conversion means starts conversion of the image data of the image file in response to a request for file information of an image file from the printer.

7. A control method of an image supply device for directly communicating with a printer and supplying image data to the printer, comprising:

a step of obtaining function information of the printer according to a communication link between the image supply device and the printer;

a step of establishing a UI based on the function information and displaying the UI;

a conversion step of converting image data of an image file according to print conditions set up based on the UI and the function information; and

a transmission step of transmitting the image data converted in said conversion step to the printer in response to a data request from the printer.

8. The control method according to claim 7, wherein the conversion in said conversion step includes at least one of resizing, color conversion and rotation of the image data.

9. The control method according to claim 7, wherein said conversion step starts conversion of the image data of the image file in response to a request for information of an image file from the printer.
