Are you sure there isn't some scaling being applied in your Acrobat print menu?
If it is, I can't see it. It would have to be in the InDesign "Export Adobe PDF" fields (since the PDF printed improperly on several different printers). I've exported the file to PDF several times, systemmatically changing each of the settings (in the Compression menu and the Marks/Bleeds menu - I needed Printer Marks on this doc) to see if it I could identify the size issue, but nothing successful thus far. Are there other areas/menus I'm missing?
I have to say I'm stumped. I wasn't aware that ID even could export a PDF at anything other than 100% of the laid-out size.

It can't. You were correct the first time. This is a case of Acrobat or Reader being set to "fit to printable area" in its print dialog.
