Removing signs of an old profile/ group policy

[hsc316]

hi

i work in a school, in which some old machines which were not in use (but previously on network before storage) had been reserected. these machines are old but they do work. however, i cannot seem to remove the old printers from each computer as the old printers which were configured on the old computers keep on appearing in place of the ones which i have installed locally on each machine. i have setup one of the computers as a print server but cannot seem to get rid of the old printers and add the new ones in to the available printers folder.

ps there is no network profile or policy running on these computers anymore.

please help and tell me how to get rid of the old printers!!!!! for the sake of my sanity
