Normally, I make a post scrip file from my indesign cs6 document and distill. Lately, i've had to convert some of my placed images as tif, rather than jpg files. Otherwise, the post script will not complete. It has now happened on some "picture" pages of my magazine project, not on other pages which do have placed jpgs. I have no idea why this is happening.
You should not have to print to postscript and then distill - the recommended workflow is to File>Export PDF.
