/**
 * Class NumberUp is an integer valued printing attribute class that specifies
 * the number of print-stream pages to impose upon a single side of an
 * instance of a selected medium. That is, if the NumberUp value is <I>n,</I>
 * the printer must place <I>n</I> print-stream pages on a single side of
 * an instance of the
 * selected medium. To accomplish this, the printer may add some sort of
 * translation, scaling, or rotation. This attribute primarily controls the
 * translation, scaling and rotation of print-stream pages.
 * <P>
 * The effect of a NumberUp attribute on a multidoc print job (a job with
 * multiple documents) depends on whether all the docs have the same number up
 * values specified or whether different docs have different number up values
 * specified, and on the (perhaps defaulted) value of the {@link
 * MultipleDocumentHandling MultipleDocumentHandling} attribute.
 * <UL>
 * <LI>
 * If all the docs have the same number up value <I>n</I> 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. Each media impression will consist of <I>n</I>m
 *  print-stream pages from the output document.
 * <P>
 * <LI>
 * SINGLE_DOCUMENT_NEW_SHEET -- All the input docs will be combined together
 * into one output document. Each media impression will consist of <I>n</I>
 * print-stream pages from the output document. However, the first impression of
 * each input doc will always start on a new media sheet; this means the last
 * impression of an input doc may have fewer than <I>n</I> print-stream pages
 *  on it.
 * <P>
 * <LI>
 * SEPARATE_DOCUMENTS_UNCOLLATED_COPIES -- The input docs will remain separate.
 * Each media impression will consist of <I>n</I> print-stream pages from the
 * input doc. Since the input docs are separate, the first impression of each
 * input doc will always start on a new media sheet; this means the last
 * impression of an input doc may have fewer than <I>n</I> print-stream pages on
 * it.
 * <P>
 * <LI>
 * SEPARATE_DOCUMENTS_COLLATED_COPIES -- The input docs will remain separate.
 * Each media impression will consist of <I>n</I> print-stream pages from the
 * input doc. Since the input docs are separate, the first impression of each

 * <UL>
 * <LI>
 * SINGLE_DOCUMENT -- All the input docs will be combined together into one
 * output document. Each media impression will consist of <I>n<SUB>i</SUB></I>
 * print-stream pages from the output document, where <I>i</I> is the number of
 * the input doc corresponding to that point in the output document. When the
 * next input doc has a different number up value from the previous input doc,
 * the first print-stream page of the next input doc goes at the start of the
 * next media impression, possibly leaving fewer than the full number of
 * print-stream pages on the previous media impression.
 * <P>
 * <LI>

 * For input doc <I>i,</I> each media impression will consist of
 * <I>n<SUB>i</SUB></I> print-stream pages from the input doc. Since the input
 * docs are separate, the first impression of each input doc will always start
