Digital's PrintServer 20 does support duplex printing and tray selection.

If you're programming in PostScript, you can use the PostScript extension
operator:

  boolean setduplexmode  --
          -------------

if the boolean value is TRUE, duplex printing is enabled starting with the next
sheet.  *One* way to select paper trays is with this PostScript extension
operator:

  integer setpapertray --
          ------------

If you're trying from an operating system to get duplex:

VAX/VMS:  $ PRINT/QUEUE=foo/PARAM=(SIDES=2) filename
U*ix:     $ lpr -Pqueue -K2 filename

Or paper trays:

VAX/VMS:  $ PRINT/QUEUE=foo/PARAM=(INPUT_TRAY={top|middle|bottom|lcit}) filename
U*ix:     $ lpr -Pqueue -Itray filename   [tray is {top|middle|bottom|lcit}]

Of course, all of this is documented in the various manuals, but I wasn't
sure of what resources you had available.
