The printer will act as if media of the chosen dimension (in
the feed direction) is present in this input source. Note
that this value will be used even if the input tray is empty.
Feed dimension measurements are taken relative to the feed
direction associated with that sub-unit and are in input sub-unit
dimensional units (MediaUnit). If the printer supports the
declared dimension, the granted dimension is the same as
the declared dimension. If not, the granted dimension is
set to the closest dimension that the printer supports
when the declared dimension is set. The value (-1) means
other and specifically indicates that this sub-unit
places no restriction on this parameter. The value (-2)
indicates unknown.
Additional information:
The objects for trays 2 and 3 reflect the
configuration of the corresponding trays. When the tray is removed, a value
of -2 is returned. The default values assume the trays are configured for
letter size paper. The object for tray 1 returns
the value of the media size for which the tray is currently configured
because it cannot sense what size media it contains.
