[Dapper] Printing real-sized negatives of things

[Brian Fahrlander]

     I have a project to make control panels for my trailer. I'm getting 
close to needing to develop the artwork, and I only have Dapper in the 
house, to say nothing of CorelDraw or Photoshop/whatever.

     I need to be able to print "white" letters on a black background, 
and be able to align the artwork with the holes to be drilled, etc.

     Is TheGimp the only simple way to do that?  I can always develop a 
JPG that Walgreen's or CVS can print in color...

     Thanks!
