Brad,

Have two copies of the PDFs, one with print disabled and one with print
enabled. Show them the print-disabled copy for them to review, and if
they want to buy it, they go back to the list of PDFs and select the
print-enabled one, you charge them, and they get the PDF. You could even
add a footer on the print-enabled one to say "Licensed for Customer
Bob's Internal Use Only" so you can track origin of prints. And on the
print-disabled one you could add a footer to the effect of "Not Licensed
for Printing."

Yes, once Bob gets the print-enabled one he can print it 100 times, but
then again, he could have printed it once and photocopied it. :) 

It's not bulletproof as you can get stuff from the web to remove the
print restrictions on PDFs, but as you said, the non tech savvy...
