 * 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 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 
 * 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.
