34 /**
35 * Class PageRanges is a printing attribute class, a set of integers, that
36 * identifies the range(s) of print-stream pages that the Printer object uses
37 * for each copy of each document which are to be printed. 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. In other words, the default value for the
53 * PageRanges attribute is always <CODE>{{1, Integer.MAX_VALUE}}</CODE>.
54 * <P>
55 * The effect of a PageRanges attribute on a multidoc print job (a job with
56 * multiple documents) depends on whether all the docs have the same page ranges
57 * specified or whether different docs have different page ranges specified, and
58 * on the (perhaps defaulted) value of the {@link MultipleDocumentHandling
59 * MultipleDocumentHandling} attribute.
60 * <UL>
61 * <LI>
62 * If all the docs have the same page ranges specified, then any value of {@link
63 * MultipleDocumentHandling MultipleDocumentHandling} makes sense, and the
64 * printer's processing depends on the {@link MultipleDocumentHandling
65 * MultipleDocumentHandling} value:
66 * <UL>
67 * <LI>
68 * SINGLE_DOCUMENT -- All the input docs will be combined together into one
69 * output document. The specified page ranges of that output document will be
70 * printed.
71 * <P>
72 * <LI>
73 * SINGLE_DOCUMENT_NEW_SHEET -- All the input docs will be combined together
74 * into one output document, and the first impression of each input doc will
75 * always start on a new media sheet. The specified page ranges of that output
76 * document will be printed.
77 * <P>
78 * <LI>
79 * SEPARATE_DOCUMENTS_UNCOLLATED_COPIES -- For each separate input doc, the
80 * specified page ranges will be printed.
81 * <P>
82 * <LI>
83 * SEPARATE_DOCUMENTS_COLLATED_COPIES -- For each separate input doc, the
84 * specified page ranges will be printed.
85 * </UL>
86 * <UL>
87 * <LI>
88 * SEPARATE_DOCUMENTS_UNCOLLATED_COPIES -- For each separate input doc, its own
89 * specified page ranges will be printed..
90 * <P>
91 * <LI>
92 * SEPARATE_DOCUMENTS_COLLATED_COPIES -- For each separate input doc, its own
93 * specified page ranges will be printed..
94 * </UL>
95 * </UL>
96 * <P>
97 * <B>IPP Compatibility:</B> The PageRanges attribute's canonical array form
98 * gives the lower and upper bound for each range of pages to be included in
99 * and IPP "page-ranges" attribute. See class {@link
100 * javax.print.attribute.SetOfIntegerSyntax SetOfIntegerSyntax} for an
101 * explanation of canonical array form. The category name returned by
102 * <CODE>getName()</CODE> gives the IPP attribute name.
