Saved PDF from View Document as PDF locks up printer

We are having a problem with View Document As PDF drawings from the PDM vault. When I view as PDF and then download and save the PDF sometimes for large files, it locks up our printer.

14516.SLDDRW.pdf - was made by PDM (locks up printer, larger file size)

14516.pdf - was made by printing as a PDF the PDF made by PDM (prints fine, file gets smaller)

This is happening about 50% of the time and becoming very annoying. I have even tried deleting the drawing file in PDM and then uploading again and still get the same problem.
