Here's another alternative - export your black artwork to a tiff file
(or eps or PDF if your software won't support tiff/jpeg/gif export).

Then, load the artwork into your favourite graphics editor. Do a 'select
areas by colour', then bucket-fill to pure magenta. Gimp supports this
really well. For *doze users, Photoshop should as well.

Then, save out the artwork as a different file and print it. Your
printer should obey just fine.

Or - if you feel like a bit of scripting - write a quick Python program
which uses the PIL API to read in the board and convert all black pixels
to magenta and save out the board. This will save all the mouse clicking
if you've got n boards to produce.

Good luck
