It was working perfectly, when I left.
It was always just ... plug it in and it works.
I always had a dedicated appletalk port on these machines, you know the roundy one.
I also had an ethernet port as well. I could print to the printer(s) in more than one way. Through the Appletalk setup or through the Network to a different computer that was "sharing" the printer out, that printed to the printer through the Appletalk setup.
If it is not working, it is broke. (master of stating the obvious, I know)
The only problem I had was on the newer MACs we had gotten just before I left, they had no Appletalk port. But we rectified that by just printing to one that did have the Appletalk port.
