We have over a dozen Zebra GK420d label printers that constantly fall off our network for no apparent reason. They have been functioning perfectly until now and nothing has changed on our network that would cause this to happen.
This thread describes the exact same issue we are having -

We have tried everything suggested in the above thread and the steps taken in the original query but nothing makes any difference whatsoever.
Has anyone else had the same issue that was resolved or could anyone maybe think of something we are missing?
