I am plotting from paperspace. I have details xrefed in to paper space and scaled. I always draw everything 1" = 1". The text in the details appears fine on the screen, but when I plot, some of the text is huge and runs off the page. Though it does not occur in all the files. I am not using annotated text or scales for anything. I have tried wblock to create new details - no luck. Have created duplicate details from one that works - no luck. 

This is a recent development, working with files that have been working fine in the past. Running 2016 on a MacBook Pro OS X El Capitan.

I've attached a screen shot (TIFF) and a copy of the PDF. TIA for your help!
