Thanks Allan, I did see your post a while back but have been holding off on an update. I think we have identified the problem and a workaround. The copier guy has been out every other day for 2 weeks and usually on the phone with KIP at some point. He rebuilt the software on the KIP along with files back and forth with KIP techs and new beta drivers back.
One issue was a buried setting in the tech's laptop that was causing an issue, don't ask me what it was. But it was causing random print failures, pages not to print, blank pages, and even corrupting files. It was a variable that was really hindering us from figuring out the issue on our end, see below.
We have some PDF's that we get back from building departments as approved sets. Some set compatibility to something like 'Acrobat 7.0 and higher'. Therein lies the issue with printing from Acrobat Pro 9, but DC was okay. We don't know the actual issue, but we've isolated it (knock on wood!). Our internal PDF's we make are now working okay on either Pro 9 or DC and use 'All supported versions' for compatibility.
But we're going to use Reader DC to print from since it somehow skirts around this issue once and for all. We'll use Pro 9 only to edit PDF's as required.
