16. A print control method comprising: receiving, from an external device, a print job that includes a plurality of ordered document files, a print page range indicating sequential target pages, an initial page in the sequential target pages corresponding to a print start page in one of the plurality of ordered document files, and a last page in the sequential target pages corresponding to a print end page in another one of the plurality of ordered document files; selectively rasterizing pages of the received print job based on the print start page and the print page range, so that the sequential target pages, including at least (i) pages between the print start page and a last page of the one document file and (ii) pages between a first page and the print end page of the other one document file, are rasterized, and the pages of the print job other than the sequential target pages are not rasterized; and printing the sequential target pages that have been rasterized, wherein the pages of the print job other than the sequential target pages are not printed.
