[Branched from InDesign Forum] Export PDF with Bleeds Larger than intended size

I am having a similar problem with the text in the book that I formatted (2 books actually). I used Palatino Linotype. When I create the PDF and print "actual size" it comes out fine--whether or not I use crop marks. However, the printer (whom I have used for years) prints from the PDF and the font comes out about 3 percent larger than intended. It takes up too much space on the page and looks very amateurish. I've tried every way I can think of and even tracked down the maker of the printer that they use. He helped me create a PDF that he felt they could print, but it still did not print correctly. I use FrameMaker 12. I am going insane!
