/**
 * Class {@code JobImpressionsSupported} is a printing attribute class, a set of
 * integers, that gives the supported values for a
 * {@link JobImpressions JobImpressions} attribute. It is restricted to a single
 * contiguous range of integers; multiple non-overlapping ranges are not
 * allowed. This gives the lower and upper bounds of the total sizes of print
 * jobs in number of impressions that the printer will accept.
 * <p>
 * <b>IPP Compatibility:</b> The {@code JobImpressionsSupported} attribute's
 * canonical array form gives the lower and upper bound for the range of values
 * to be included in an IPP "job-impressions-supported" attribute. See class
 * {@link SetOfIntegerSyntax SetOfIntegerSyntax} for an explanation of canonical
 * array form. The category name returned by {@code getName()} gives the IPP
 * attribute name.
