Claim:
A printing control system comprising: operation means configured to enter a first printing condition including information on the number of page images to be printed on one printing sheet and the total number of page images to be printed; display means; control means configured to set a final printing condition based on the first printing condition entered by the operation means; and printing means configured to perform printing under the final printing condition set by the control means, wherein: the control means changes the first printing condition to one or more second printing conditions that provide higher ratios of reduction n the usage of printing sheets than the first printing condition to compare the ratios of reduction in the usage of printing sheets provided by the one or more second printing conditions to a preset threshold value of ratio of reduction in the usage of printing sheets; when the ratios of reduction in the usage of printing sheets provided by the one or more second printing conditions are less than the threshold value, the control means sets the first printing condition as the final printing condition; when the ratios of reduction in the usage of printing sheets provided by the one or more second printing conditions are not less than the threshold value, the control means causes the display means to display the one or more second printing conditions that provide the ratios of reduction in the usage of printing sheets which are not less than the threshold value; and the operation means includes selection means configured to select the final printing condition from the first printing condition and the one or more second printing conditions displayed by the display means.
