Border printed on every page in Preview but not Adobe Reader after creating pdf in Microsoft Office 2011 14.6.2 Update

I just printed a page of Avery labels directly in Word (not from a pdf), and I got the border on that document also. Then I printed another Word document that came from a friend, and the border showed up again, so this problem isn't confined to printing pdf files. Perhaps I'll try reinstalling the printer driver.

I had to repost this:

I just printed a page of Avery labels directly in Word (not from a pdf), and I got the border on that document also. Then I printed another Word document that came from a friend, and the border showed up again, so this problem isn't confined to printing pdf files. It appears in Preview in every case, but if I save it as an Adobe Reader file, and open it in Adobe Reader, it does not have the border. If I open the Adobe Reader file in Preview I don't see the border until I go to print. When I do, the border appears in the Preview pane of the print dialog window and prints with the border. It is beginning to sound like a problem with Preview. I'll change my default pdf application from Preview to Adobe Reader, restart, and report back to see if this is a work around.

This is embarrassing to have to admit, but someone on the Microsoft forums pointed me to an option that I had never seen or used on the print dialog box. There is an option to print with a thin border! And that had somehow gotten set. Back in my head, I had always suspected that there was some simple setting that I was overlooking, but I really didn't know where to go to find it. I have no idea how it got set.
