Neil,

Using the GARP "File-->save" menu, you can save the image to a gif file,
then use one of the freely available programs like "xv" to change the
background color. Imagemagick and/or ghostscript are good for converting
gifs to postscript for printing too.

Of course, from sncorss or sncross2 you can use the "ps" device to create
postscript output for printers. The postscript files will print clearer than
bit map screen dumps (and they don't fill the background).
