Image processing apparatus and method

An image processing apparatus, which is connected via a predetermined interface, comprising:

• determination means for, based on predicted data, determining whether image transmission will be successful without a buffer memory being used;
• and
• reception means for, when said determination means determines that the buffer memory is not required for the image transmission, receiving image data without using the buffer memory, and for, when said determination means determines that the buffer memory is required for the image transmission, using the buffer memory and receiving said image data,
• wherein the interface is an IEEE 1394 serial bus.

An image processing apparatus, which is connected via a predetermined interface, comprising:

• determination means for determining whether an obtained bandwidth is satisfactorily high;
• and
• control means for, when said determination means determines that the bandwidth is satisfactorily high, controlling a printer engine so as to perform printing at a maximum processing speed, and for, when said determination means determines that the bandwidth is not satisfactorily high, determining a processing speed in accordance with the obtained bandwidth and controlling the printer engine so as to perform printing at the determined processing speed,
• wherein the interface is an IEEE 1394 serial bus.

An image processing apparatus, which is connected via a predetermined interface, comprising:

• determination means for determining whether an obtained bandwidth is satisfactorily high;
• and
• control means for, when said determination means determines that the bandwidth is satisfactorily high, controlling a printer engine so as to perform printing at a minimum paper interval, and for, when said determination means determines that the bandwidth is not satisfactorily high, determining a paper interval in accordance with the obtained bandwidth and controlling the printer engine so as to perform printing at the determined paper interval,
• wherein the interface is an IEEE 1394 serial bus.

A control method, for an image processing apparatus that is connected via a predetermined interface, comprising:

• a prediction step of, in accordance with a use state of the interface, predicting an end time for transmission of image data for a target job of a plurality of jobs that are executed at a same time;
• and
• a control step of controlling a timing for an output operation, in accordance with a result obtained at said prediction step,
• wherein the interface is an IEEE 1394 serial bus.
