Tom,

Of course the root cause of the printing time problems
is the inefficiency of capturing a raw bitmap from the 
screen and embedding this in postscript. We could get a 
much better information packing density in the postscript 
file if we embedded a program in DM that scanned the 
display list and converted it directly to postscript. 
We have not pursued this in the past because we were
were not encouraged by the magnitude of the task vs. the
expected return. Perhaps the size of this task would be more 
reasonable, and achievable, if we initially compromised 
and converted all active elements to text thereby 
avoiding the need to code a postscript rendering engine 
for bars, valuators, etc. It is also possible that
this program could be patched as a library that could
be shared between dm and medm.

Jeff
