I will try to post as many dettails as possible because this problem is costing us too much.
We have a small office with 4 computers and just bought a new printer xerox 5330. We connected the printer on the switch that distributes internet in all our computers. At first it seemed to be printing fine but then the printer appears to be offline with an exclamation point.
And when it comes online i get the message "printer is not avaliable at this time". I checked the ip and its the same on all computers so i dont think is that. The latest drivers are installed. All computers have windows 7.
