Wow! A blast from the past. I have run into this exact issue a number of years ago an a machine running PlotBase. The problem is the layers in the CAD file are not being flattened properly. The file explodes when you try to plot it. The one solution I found was to open the offending file in Photoshop and then use Photoshop to convert it to a pdf or tiff and then plot it. Other than that you'd have to educate the person creating the pdfs with Bluebeam on how to get their settings correct and make good pdfs. They have to flatten the pdf.....otherwise the plotter software or driver will have to do it.
I spent hours on this issue. The customer was convinced it was my machine's fault. Ricoh was little help. Finally I found that the common denominator was in the properties of the file and the PDF producer was Bluebeam. Any time we hit a pdf created with this software the file wouldn't print.
