prtinputdefaultindex

The value of prtInputIndex corresponding to the default input
sub-unit: that is, this object selects the default source of
input media. 
This value shall be -1 if there is no default input subunit specified
for the printer as a whole.  In this case, the actual default
input subunit may be specified by means outside the scope of this
MIB, such as by each interpreter in a printer with multiple
interpreters.
Refer to Standard Printer MIB for more details.
        Additional information:
        The default input tray is determined by the printer
        based on DEFAULT-MEDIA-SIZE and DEFAULT-MEDIA-NAME, and whether or
        not optional trays are installed. 
        If Tray 1 is set in FIRST mode then the size of paper loaded in
        Tray 1 is assumed to be the requested size. In this case, the printer will
        pick from Tray 1 without regard to the requested size unless the
        print job's paper size, paper type and tray designations exactly
        match the configuration of another tray; in that case, the requested
        tray will be picked.
