prtinputdefaultindex

1.3.6.1.4.1.11.2.3.9.4.2.2.5.1.1.6

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. 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.
