I'm using the technique outlined at this link:
http://whatrevitwants.blogspot.com/2010/03/how-to-print-large-set-of-drawings-to.html
After I print three docs, i end up with a single document named REDMON_DOCNAME_FILE.
It does go to the correct folder. This occured on two separate machines. I used this technique successfully in the past.
I have installed and reinstalled the latest version.
