I am not sure what you mean by print restrictions.
We usually download from ANSI (ansi.org). Due to poor internal communication, we ended up buying two copies of ISO 9001:2000 - one from ASQ and one from ANSI. The ASQ version did not allow me to copy text, but the ANSI did. This way I am able to convert to a text file and transfer to my palm computer. Not sure if this is coincidence or policy differences between the download sites. Our 14K (full set of all standards) allows copy & paste also.
I have printed all of the standards (9K, 14K, TS, 17025...) we have on the network dozens of times with no problems. I don't believe that acrobat can count the number of times you print, but you can prevent printing alltogehter.
Standards of Australia used to include a special 'plugin' which only allowed 1 print. I think someone said a while ago that they don't do that any more, but when I bought seveal standards from them a couple of years ago they did.
