for you mac users there is a relatively simple work around and its pretty much the same on pc
you need to go in and change the image to a pure b&w 1 bit image thereby eliminating any color output. Any image that is not 1 bit even though it looks like its b&w on screen will have color information embedded in the file - it will have more going on than you can see - rbg or cymk encoding is the issue. There are many shades and variations of black in the printing world and mac being the ultimate printing graphics toy is designed to address these issues so blacks can be warm or cold and blend in with sophisticated art layouts and not look harsh.
By reducing the image to 1 bit you have only black and nothing else. So black will be solid and white will be clear.
its takes some tweedling - when R. Cameron was her we hooked his mac to my hp and epsons and it drove us nuts with the off color images on the transparencies.
You will have to readjust the gamma to get on screen relationship to equal print output
what appears as a faint light grey on screen will print pure black. Contrast will probably not be something you will need to mess with as there is none. The only thing is the quantity of black ink you will be pumping and it will be more than is required to do a transfer. SO much in fact that you may have to wait a while for the transparency to dry down to avoid smudging.
When you get it right save it as a controled printer setting and you can repeat it for other graphics
if you want to make life simple

ther are probably a zillion other utilities that can be had for free if you google enough
good luck
