This is a great request. In our environment, we have over 1,000+ locations and some have different floors/Rooms. Can't control printing will become a major issue. We want the user to be able to print but at the same time, we want to restrict the access by specify some conditions.
For example, when the user logs into a computer within her/him assigned work location (building) and floor/Room, user can print (allow). If user is login to a computer outside of the range, user cannot print (block).
If not by user, maybe make printer available only on provided computer (we can identify the computer information and set only this computer can print to this printer).
UP is great but without some ways to restrict user access things can get very wrong in real life situation.
