Patent ID: 6970257

Claim:
A printing system including an image processing section and a printing section to perform printing on a printing medium based on image data, said system comprising: a memory for storing the image data; first processing means for executing image data magnifying processing by means of a software, based on first magnifying rate information; and second processing means for executing the image data magnifying processing for an image to be printed based on the image data magnified by said first processing means, based on second magnifying rate information indicating the magnifying rate greater than 100%, wherein the image data magnified by said first processing means is stored in said memory, and said first magnifying rate information is determined based on at least one of a resolution of printing performed by said printing section, a processing load to be borne by said first processing means, a capacity of said memory and a resolution shown by the image data, and a magnifying rate of the image to be printed on the printing medium based on the image data, such that the higher the resolution of printing is, the smaller the processing load is, the larger the capacity of the memory is, or the lower the resolution shown by the image data is, said first magnifying rate becomes larger and said second magnifying rate becomes smaller, and wherein said second processing means controls the number of times of repetition of pixels shown by the image data magnified by said first processing means to magnify the image data, based on said second magnifying information.
