Disable Printer Auto Install (WinXP)

hi, guess the Topic says a lot about my Question.

One of my clients has a small 12-hosts network and is running XP… they asked me to look out why the shared printers keep Auto Installing on every host in the network. I was shocked, I never stopped to wonder why XP does this, cuz I guess I did’nt care, I know this is provably something easy to do, I just started to search how to do it on the knowlegde base but thought about dropping it here. =)
