    UNIX GRASP has full printing capability as long as you can
print PostScript, which if you are using UNIX/Linux you almost
certainly can.

    Also in our defense, we did need to switch to Java. After some
initial start up overhead, we're making much more progress
this way, plus we can eventually port to Mac, etc with little work.
jGRASP is usable on a P300, which is slow by today's standards, and
speed is not a concern at all on a P3-550 or better. On SPARCs the
performance is not so good, but that hardware will catch up
eventually - display/graphics speed is the main problem.
