Description: The value of prtInputIndex corresponding to the input subunit which will be used when this input subunit is emptied and the timeout specified by prtInputMediaLoadTimeout expires. A value of zero(0) indicates that auto input switching will not occur when this input subunit is emptied. If the timeout specified by prtInputLoadMediaTimeout expires and this value is zero(0), the job will be aborted. A value of (-1) means other. The value (-2) means 'unknown' and specifically indicates that an implementation specific method will determine the next input subunit to use at the time this subunit is emptied and the timeout expires. The value(-3) means input switching is not supported for this subunit. Refer to Internet Draft Printer MIB, expiring Sept. 1997 for more details. Additional information: This object reflects the state of JOB-INPUT-AUTO-CONTINUE-MODE and JOB-INPUT-AUTO-CONTINUE-TIMEOUT. If JOB-INPUT-AUTO-CONTINUE-TIMEOUT is set to -1 or JOB-INPUT-AUTO-CONTINUE-MODE is set up to cancel the job, this object will return 0. If JOB-INPUT-AUTO-CONTINUE-TIMEOUT is >= 0 and JOB-INPUT-AUTO-CONTINUE-MODE is not set up to cancel the job, this object will return -2, meaning that a product-specific tray switching action will occur.
