Printer Default refresh

Throwing this out there for anyone that might have run into it before...

There's a small domain with about 6 computers. Each station has it's own black and white printer, but this Epson Stylus is the color printer and it's shared out on one of the machines not used everyday. Well, it refreshes itself as the default on all the computers that have it installed through the network.

So, even though each workstation has their local printer the default, the epson does something and sets itself as the default on all the computers that have it installed through the network.

Any suggestions would be worthy of Valhalla.
