/**
 * Class PagesPerMinuteColor is an integer valued printing attribute that 
 * indicates the nominal number of pages per minute to the nearest whole number 
 * which may be generated by this printer when printing color (e.g., simplex, 
 * color). For purposes of this attribute, "color" means the same as for the 
 * {@link ColorSupported ColorSupported} attribute, namely, the device is 
 * capable of any type of color printing at all, including highlight color as 
 * well as full process color. This attribute is informative, not a service 
 * guarantee. Generally, it is the value used in the marketing literature to 
 * describe the color capabilities of this device. A value of 0 indicates a 
 * device that takes more than two minutes to process a page. If a color device 
 * has several color modes, it may use the pages-per- minute value for this 
 * attribute that corresponds to the mode that produces the highest number. 
 * <P>
 * A black and white only printer must not include the PagesPerMinuteColor 
 * attribute in its attribute set or service registration. If this attribute is 
 * present, then the {@link ColorSupported ColorSupported} printer description 
 * attribute must also be present and have a value of SUPPORTED. 
 * <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>
