Initially I was having problems with print speed on my office Dell 3115cn MPF. I was reading some dialogue message about "spooling X%". The percentage gradually moved up, but it would take up to a minute to print a single page. After reviewing my other co-workers print settings, all are set up via IP printing, I removed and re-added the printer several times. Now the printer wont function at all. It is giving me a "network busy" message. Any help is appreciated.
