How to restrict printing

When we create a drawing, we use Matthew Lorono's SaveAsPDF with Folder Selection macro and it works perfect. Now I am needing to go a bit further with it. I need to be able to restrict printing per user login of the PDF's we create. I can't just lock it down from everyone because there are a few that still need to be able to print and we have a program we use for our shop travelers that needs to be able to print the PDF's.

Any ideas?

Thanks in advance,

Brian
