Whether all pages have the same print settings is determined before print settings are changed in a print preview, and the setting change is permitted only when all pages have the same print settings. In each layer of XPS data to be processed, whether the print setting information is not added to the element of the layer or whether the print setting information added to the element of the layer is shared by all elements of the layer is determined. A change in the print setting information by the user is accepted if one of the conditions is satisfied. When the print settings are changed, the setting change is not reflected on individual print tickets. The change is reflected on the entire job by adding a print ticket reflected with the setting change on the top element.
