I tried to export to PDF. The file took up the entire PDF page as opposed to beign 3.5X4.5 inches.
What is the page size as listed in Acrobat, what is the Page size in InDesign (as shown in File > Document Setup)
Two things come to mind - They are the same page size, but Acrobat is filling the viewing area (normal behavior) whereas the old file had the Initial View set to pahaps 100%.
Confirm that you exported from InDesign and did not Print to PDF (Page Scaling could be invoked from the print to)
You are correct in that I exported from InDesign and did not Print to PDF. The page size in InDesign is 3.5x4.5. When I tried to print after exporting my InDesign file, the file took up the whole page and did not stay within the 3.5x4.5 page set up. Thoughts?
What is the Acrobat page size, I'm expecting 3.5 x 4.5 (InDesign export is pretty rock solid), and Page Scaling was enabled when printing from acrobat...
If this is not the case a screen shot might help
