Nothing is printed 38 * for any pages identified that do not exist in the document(s). The attribute 39 * is associated with <I>print-stream</I> pages, not application-numbered pages 40 * (for example, the page numbers found in the headers and or footers for 41 * certain word processing applications). 42 * <P> 43 * In most cases, the exact pages to be printed will be generated by a device 44 * driver and this attribute would not be required. However, when printing an 45 * archived document which has already been formatted, the end user may elect to 46 * print just a subset of the pages contained in the document. In this case, if 47 * a page range of <CODE>"<I>n</I>-<I>m</I>"</CODE> is specified, the first page 48 * to be printed will be page <I>n.</I> All subsequent pages of the document 49 * will be printed through and including page <I>m.</I> 50 * <P> 51 * If a PageRanges attribute is not specified for a print job, all pages of 52 * the document will be printed.
