I have noticed something since we upgraded to OS9.1. several of the computers on our LAN will forget the printer that has been choosen in the chooser (adobePS) when we try to print. If I go in the chooser and pick the printer again it will work fine for awhile, a day, a week, it is random. Has anyone ran across this before? Not sure if it is something with 9.1 or not but it only happens on the computers that have 9.1 running.
