Driver program and transfer method for data

A driver program for causing a host apparatus to execute a processing of generating image data comprising data of a plurality of colors and transferring said image data to a printing apparatus, wherein

• when the transfer of said image data of one plane is conducted, the driver program causes said host apparatus to execute
• a first step of transferring to said printing apparatus the data of all or some colors of said plurality of colors by each band of bands obtained by dividing said image data of one plane at a prescribed height and storing the data of colors that are not transferred in said host apparatus when said transfer is conducted with respect to the data of said some colors, and
• a second step of transferring the data stored in said first step to said printing apparatus by each color of said plurality of colors.

A transfer method for data for transferring image data comprising data of a plurality of colors generated in a host apparatus to a printing apparatus, wherein

• when the transfer of said image data of one plane is conducted, said image data transfer is conducted by intermingling
• a step of transferring to said printing apparatus by each band of bands obtained by dividing said image data of one plane at a prescribed height, and
• a step of transferring to said printing apparatus by each color of said plurality of colors.
