Description: The remaining capacity of the possible output sub-unit capacity in output sub-unit capacity units (PrtCapacityUnitTC) of this output sub-unit. If this output sub-unit can reliably sense this value, the value is sensed by the printer and may not be modified by management requests; otherwise, the value may be written (by a Remote Control Panel or a Management Application). The value (-1) means other and specifically indicates that the sub-unit places no restrictions on this parameter. The value (-2) means unknown. The value (-3) means that the printer knows that there remains capacity for at least one unit. Refer to ftp://ftp.pwg.org/pub/pwg/pmp/drafts/pmib_031698.txt, for more details in the Standard Printer MIB. Additional information: Replaces PML NOT-READY-OUTBIN-FULL and STATUS-OUTBIN-FULL. The values reported for output sub-unit 1 (face-down, top bin) will be either (-3) if it is not full or (0) if it is full.Output sub-unit 2 (face-up, left side bin) does not have any sensing, so it will always report unknown (-2).
