I can echo Steve's results, but I, however, -am- on vanilla 08.
I use aerials, vicinity maps... usually PNGs, sometimes TIF, sometimes JPG (ew), sometimes even a bmp (ew)
What kind of image, what file size of image, what resolution, how is it inserted into your drawing, what are the settings for your drawing's properties for image display... visual style.. object properties of the image... there's many things you could just be overlooking that will intentionally not print the contents of an image.
Can you upload a sample drawing for disection?
