/**
|
|
* Class PageRanges is a printing attribute class, a set of integers, that
|
|
* identifies the range(s) of print-stream pages that the Printer object uses
|
|
* for each copy of each document which are to be printed. Nothing is printed
|
|
* for any pages identified that do not exist in the document(s). The attribute
|
|
* is associated with <I>print-stream</I> pages, not application-numbered pages
|
|
* (for example, the page numbers found in the headers and or footers for
|
|
* certain word processing applications).
|
|
* <P>
|
|
* In most cases, the exact pages to be printed will be generated by a device
|
|
* driver and this attribute would not be required. However, when printing an
|
|
* archived document which has already been formatted, the end user may elect to
|
|
* print just a subset of the pages contained in the document. In this case, if
|
|
* a page range of <CODE>"<I>n</I>-<I>m</I>"</CODE> is specified, the first page
|
|
* to be printed will be page <I>n.</I> All subsequent pages of the document
|
|
* will be printed through and including page <I>m.</I>
|
|
* <P>
|
|
* If a PageRanges attribute is not specified for a print job, all pages of
|
|
* the document will be printed. In other words, the default value for the
|
|
* PageRanges attribute is always <CODE>{{1, Integer.MAX_VALUE}}</CODE>.
|
|
* <P>
|
|
* The effect of a PageRanges attribute on a multidoc print job (a job with
|
|
* multiple documents) depends on whether all the docs have the same page ranges
|
|
* specified or whether different docs have different page ranges specified, and
|
|
* on the (perhaps defaulted) value of the {@link MultipleDocumentHandling
|
|
* MultipleDocumentHandling} attribute.
|
|
* <UL>
|
|
* <LI>
|
|
* If all the docs have the same page ranges specified, then any value of {@link
|
|
* MultipleDocumentHandling MultipleDocumentHandling} makes sense, and the
|
|
* printer's processing depends on the {@link MultipleDocumentHandling
|
|
* MultipleDocumentHandling} value:
|
|
* <UL>
|
|
* <LI>
|
|
* SINGLE_DOCUMENT -- All the input docs will be combined together into one
|
|
* output document. The specified page ranges of that output document will be
|
|
* printed.
|
|
* <P>
|
|
* <LI>
|
|
* SINGLE_DOCUMENT_NEW_SHEET -- All the input docs will be combined together
|
|
* into one output document, and the first impression of each input doc will
|
|
* always start on a new media sheet. The specified page ranges of that output
|
|
* document will be printed.
|
|
* <P>
|
|
* <LI>
|
|
* SEPARATE_DOCUMENTS_UNCOLLATED_COPIES -- For each separate input doc, the
|
|
* specified page ranges will be printed.
|
|
* <P>
|
|
* <LI>
|
|
* SEPARATE_DOCUMENTS_COLLATED_COPIES -- For each separate input doc, the
|
|
* specified page ranges will be printed.
|
|
* </UL>
|
|
* <UL>
|
|
* <LI>
|
|
* SEPARATE_DOCUMENTS_UNCOLLATED_COPIES -- For each separate input doc, its own
|
|
* specified page ranges will be printed..
|
|
* <P>
|
|
* <LI>
|
|
* SEPARATE_DOCUMENTS_COLLATED_COPIES -- For each separate input doc, its own

|

|
|
* </UL>
|
|
* </UL>
|
|
* <P>
|
|
* <B>IPP Compatibility:</B> The PageRanges attribute's canonical array form
|
|
* gives the lower and upper bound for each range of pages to be included in
|
|
* and IPP "page-ranges" attribute. See class {@link
|
|
* javax.print.attribute.SetOfIntegerSyntax SetOfIntegerSyntax} for an
|
|
* explanation of canonical array form. The category name returned by
|
|
* <CODE>getName()</CODE> gives the IPP attribute name.
