I work in a computer lab on a college campus. We have just 5 Mac stations that are using OS X. We have two printers setup via IP Address in the Print Center. One is a color HP Laserjet and the other is a black/white HP laserjet.

The problem we're having is that students are able to delete the printers from the Print Center (using the toolbar, I assume). I would venture to guess that they are trying to delete their print job, but are removing the printer itself instead.

I have tried hiding the toolbar so they wouldn't have the add/delete options, but the toolbar just re-appears eventually.

Is there a way I can prevent the printers from being deleted?
