I had a large document that took days to lay out.  When I went to print, it
would print out a page or two correctly, then half-way down some pages it would
stop rendering and I'd get all white.  Later in the document, one or two pages
would come through correctly, while others might show up all white.

I finally narrowed it down to pages with several images on it.  Being that
there's no good way to put a different full-page image in the background per
page (really infuriating, by the way) while maintaining margins, I have to
insert a frame for each page and maximize it, put an image there, then create
another frame above it to create a text region similar to where margins would
be.  Often, I'll create several frames with different images at different
transparency levels all floating above this background frame.

The pages that failed always had a frame with a large background image, several
floating images in other frames, and text inside them or inside the full-page
frame.  It would render most of the page until it finished the last line of one
of the floating pictures, then the rest of the page would be blank.

I had to spend three days converting the doc by hand to MS Word, because both
Print and Export to PDF features failed exactly the same way.  Printing one page
at a time or in bulk had the same behavior.

Thanks.
