help on graphic output

[rpg@CS.BROWN.EDU]

Two questions:

1)  Do any of you have software for drawing line graphs on the
symbolics screen?

2)  Our symbolics' are second-class citizens of our network.  In
particular, they are not connected to any printers.  But we have a
couple of printers that take postscript output.  Is there any way to
snapshot a screen or window, and get a postscript file that I could
ship to one of these printers?

These seem to be pretty basic questions, so it's probably best not to
put the answers on the list.  I'll collect them, summarize and mail
them out.

Thank you all,
Robert
