 * lower and upper bounds of the total sizes of print jobs in number of media
 * sheets that the printer will accept.
 * <P>
 * <B>IPP Compatibility:</B> The JobMediaSheetsSupported attribute's canonical
 * array form gives the lower and upper bound for the range of values to be
 * included in an IPP "job-media-sheets-supported" 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.
