What's the printer? What patch level on ID? Waht printer settings?
Can you print other files -- from ID and other apps?
Problem solved, it was a bad font, of all things. I was using Gentium 1.02 in the document, and changing that for Geneva made the error go away. I was able to download a newer version of Gentium and swap it in, and all continues to work. It would have been nice to get a real error from ID but at least the problem is solved
