Description: The printer will act as if media of the chosen dimension (in the cross feed direction) is present in this input source. Note that this value will be used even if the input tray is empty. The cross feed direction is ninety degrees relative to the feed direction associated with this sub-unit. This dimension is measured 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 they cannot sense what size media it contains.
