I guess it was the third option then, not the second ;-) What does
RC_IMAGE do if you are already running SNNS when you start it up?

In V14.5 -ved_print- supplies a mechanism for sending the new VED files
to PostScript printers:

    <ENTER> print -o ps

JohnG was very careful with the coding mechanism for the new graphic
characters/underlining/italic etc. These should be legable on almost all
printers which move back a character when recieving a backspace
character. I've yet to have a problem getting the new format to print
out successfully.
