I work at a print shop, and we're having problems printing from our PDFs to the size of the document. For instance, we'll get an 8.5 x 11 file and even though it appears correct on the screen, the art work will shrink when printed directly from Acrobat. It does not shrink significantly, but enough so that it would throw off the design or the matching up of a booklet or something along the lines of that. Does anyone know if this is a setting issue or maybe a bug in an earlier version of Acrobat?
Are you sure you don't have "shrink to printable area" selected in the print menu?
