     Although you do not say which laser printer you are driving, I'm
assuming that with your Suns, you also have a LaserWriter printer.  In
this case, InterLeaf must produce a PostScript program which renders your
pages on the LaserWriter.  The LaserWriter does not understand the InterLeaf
internal format directly.  If there is a printer which prints directly from
some InterLeaf internal format, I haven't heard of it.

     In any case, you should be able to take the PostScript produced by
InterLeaf, and send it directly to any other PostScript printer, and get
equivalent results, within the resolution offered by the printer.  For
high resolution output, you may want to search out a local print shop
with a Linotronic typesetter, which understands PostScript.  The Linotronic
100 offers about 1200 dpi, and the Linotronic 300 provides 2540 dpi.

     These machines are expensive, and renting time may be expensive too.  If
you are rendering scaled bitmaps, this could really be expensive.  I heard 
that a full page image can take up to 10 hours to render on a Linotronic,
since the amount of data is so massive (603,224,600 bits for 8.5 x 11 at
2540 dpi).
