I must not have been very clear, sorry.
I will explain it as just one classroom.
I have a total of 8 computers in the classroom, the teachers computer and 7 student computers. These are all in the same room all the time. The business office has purchased 1 USB printer for each teacher. Now my job is to get the students printing to it. I have already shared the printer out on the Teacher computer and now just need to add it to every child computer. I was envisioning using a computer list in workgroup manager to run a logon script. Since we are using network homes when each student logs in the printer that they may have used in the Library or elsewhere may be remembered. So I wanted to delete any exsisting printers and add the correct printer for that room. I would love to be able to use the computer list to manage which printer they use, however since it is a shared printer it does not show up as an option. I hope that is a little better description.
