   Thanks for your advice (and the others who suggested dw:do-redisplay)
Both methods work, more-or-less, and they seem to generate Postscript
along the lines that you have described but with one slight difference:

   You had suggested that it defines a posscript function (once).
Instead the program sends the entire print-spec over each time it
moves the viewport.  Although this works, it is extremely inefficient.
The print file I generate eats up around 6MB+ and takes an awfully long
time to print (Longer than bitmap??)

  Is this a G7.2 problem that has been solved in later versions of
Genera?  (Not that it helps me).  Is there anyway to work around this
problem?...A patch for the printer system perhaps?...A different
function to use?

   Incidentally, the dw:do-redisplay function failed to print the entire
graphic.  I don't know why.


P.S.  The method:  :WITH-PAGES-FOR-BOX takes the arguments:
  What is XSTREAM?  I bound it to stream (which is the same as the
flavor to which I'm sending it) and that seems to work, but I can't
imagine that that is the correct usage.
