Description: The unit that will be used by the printer when reporting counter values for this marking sub-unit. The time units of measure are provided for a device like a strip recorder that does not or cannot track the physical dimensions of the media and does not use characters, lines or sheets. Refer to Internet Draft Printer MIB, expiring Sept. 1997 for more details. Additional information: Since the Laserjet 1220 product keeps track of pages printed, the counter unit will be defined as ePimpressions which would be like saying pages printed. (The term 'impressions' is used instead of 'pages' to avoid confusion between 'sheets' and 'pages' on a duplexing printer. This confusion isn't a problem with the Laserjet 1220 product because it has no duplexer.)
