Abstract
An information processing apparatus according to the present invention determines whether a slip sheet should be inserted after a page of interest has been printed according to at least one of the paper type for the page and the size of an object on the page. If it is determined that a slip sheet is necessary for the page, a slip-sheet insert command for inserting a slip sheet for the page is automatically issued.
Claims18
An information processing apparatus comprising:
- a determination unit configured to determine whether or not a ratio of an image region in a page is equal to or larger than a threshold value;
- a control unit configured to control a printer to print the image on a sheet without inserting a slip sheet when the determination unit determines the ratio of the image in the page to be smaller than the threshold value and to print the image on the sheet with inserting the slip sheet when the determination unit determines the ratio of the image in the page to be equal to or larger than the threshold value;
- and
- a second determination unit configured to determine whether the slip sheet is inserted for a previous page during double-sided printing,
- wherein the control unit controls the printer to print the image on the sheet without inserting the slip sheet when the second determination unit determines that the slip page is inserted for the previous page, controls the printer to print the image on the sheet without inserting the slip sheet when the second determination unit determines that the slip sheet is not inserted for the previous page and the determination unit determines that the ratio of the image in the page is not equal to or larger than the threshold value, and controls the printer to print the image on the sheet with inserting the slip sheet when the second determination unit determines that the slip page is not inserted for the previous page and the determination unit determines that the ratio of the image in the page is equal to or larger than the threshold value.

An information processing apparatus comprising:
- a determination unit configured to determine whether or not a number of pixels having a pixel density value equal to or larger than a fist threshold value is equal to or larger than a second threshold value;
- a control unit configured to control a printer to print an image on a sheet without inserting a slip sheet when the determination unit determines the number of the pixels having the pixel density value equal to or larger than the first threshold value to be smaller than the second threshold value and to print the image on the sheet with inserting the slip sheet when the determination unit determines the number of the pixels having the pixel density value equal to or larger than the first threshold value to be equal to or larger than the second threshold value;
- and
- a second determination unit configured to determine whether the slip sheet is inserted for a previous page during double-sided printing,
- wherein the control unit controls the printer to print the image on the sheet without inserting the slip sheet when the second determination unit determines that the slip page is inserted for the previous page, controls the printer to print the image on the sheet without inserting the slip sheet when the second determination unit determines that the slip sheet is not inserted for the previous page and the determination unit determines that the ratio of the image in the page is not equal to or larger than the threshold value, and controls the printer to print the image on the sheet with inserting the slip sheet when the second determination unit determines that the slip page is not inserted for the previous page and the determination unit determines that the ratio of the image in the page is equal to or larger than the threshold value.
