Neil,

You could either:

1) Print as postscript directly from nmap2 instead convering the gif from 
   garp for your printer. The NMAP postscript output will invert the black
   and white for just the reason you mention.
2) create a modified color table with the minimum data value set to white
   instead of black.
3) Use an external graphics program that can manipulate the gif color
   index setting black to white.
