Print Management Console can be used on non-R2 servers
Coming from Aaron Tiensivu:
One of the R2 feature specific management tools that is in the admin tool pack that a lot of people don't realize can be used on non-R2 servers is the Print Management Console. I've blogged about it before, but I try to put it on any XP box or server I'm maintaining due to the ability to get a nice quick snapshot of what drivers are loaded on servers at a location. The 'published printers' section will be empty on non-R2 systems.
With the official release of MMC 3.0 for everyone, it makes sense to install this now more than ever.
