Booklets that I create with InDesign print perfectly. When I convert to PDF and print, there is a shrinking of the text and a pulling in of each page from the outer margins. I don't know how to solve this problem. It happens whether I try to print the PDF from Mac or PC. But the InDesign original file prints without the shrinking and pulling in of margins.
Almost always, when you experience this problem, it's because the setting in the Print dialog of Reader or Acrobat is set to Fit the page which causes page scaling as you describe. Check your Print settings.
