/**
 * Class JobMediaSheets is an integer valued printing attribute class that
 * specifies the total number of media sheets to be produced for this job.
 * <P>
 * The JobMediaSheets attribute describes the size of the job. This attribute is
 * not intended to be a counter; it is intended to be useful routing and
 * scheduling information if known. The printer may try to compute the
 * JobMediaSheets attribute's value if it is not supplied in the Print Request.
 * Even if the client does supply a value for the JobMediaSheets attribute in
 * the Print Request, the printer may choose to change the value if the printer
 * is able to compute a value which is more accurate than the client supplied
 * value. The printer may be able to determine the correct value for the
 * JobMediaSheets attribute either right at job submission time or at any later
 * point in time.
 * <P>
 * Unlike the {@link JobKOctets JobKOctets} and {@link JobImpressions
 * JobImpressions} attributes, the JobMediaSheets value must include the
 * multiplicative factors contributed by the number of copies specified by the
 * {@link Copies Copies} attribute and a "number of copies" instruction embedded
 * in the document data, if any. This difference allows the system administrator
 * to control the lower and upper bounds of both (1) the size of the document(s)
 * with {@link JobKOctetsSupported JobKOctetsSupported} and {@link
 * JobImpressionsSupported JobImpressionsSupported} and (2) the size of the job
 * with {@link JobMediaSheetsSupported JobMediaSheetsSupported}.
 * <P>
 * <B>IPP Compatibility:</B> The integer value gives the IPP integer value. The
 * category name returned by <CODE>getName()</CODE> gives the IPP attribute
 * name.
 * <P>
