mp-tray

Returns or changes the value of the multi-purpose (MP)
tray configuration variable.  The MP tray can be
configured to operate as an additional input tray
(eCassette), a manual feed slot (eManual), or in a
manner compatible with the LaserJet III manual feed slot
(eFirst).  If configured for eFirst, if media is present
in the MP tray, that media is used (assuming the size
matches and the print job didn't specify another tray)
until the MP tray is empty.
Additional information:
This object can be set when the printer is not idle, and will return <noError> if 
successful, but the change will not affect the current job since the printer's default value, not the current value,
is being changed.  
          
When this tray is configured to eFrist, an assumption is made that the media size is correct--it is not checked.
