Hmmm after further experimenting with different pdf viewers and printers, I've decided that these files are *very* unfriendly. I'm feeling lucky I can open the things at all.

I have a feeling the pdflrf is gonna be the best thing I can do, hopefully I can knock down the conversion time with tweaking.
So to laborg, don't worry about this issue. These files are doomed to screw everything up until I march to adobe with a pitchfork and get them to stop borking their files with drm.
Thanks for the attention, guys.
