Tracking down a network problem affecting HP P2055 Printers - Suggestions?
We have what appears to be an intermittent and seemingly random problem whereby our HP P2055 (about 10 of them) series printers will eventually stop responding to any kind of network traffic (ping,web interface) after being connected to our network for a day or two.
I've tried plugging the printers into a standalone switch and they're fine so I can only assume the problem is caused by another PC/device connected to our network sending out packets which causes the NIC/Jetdirect card on this particular model to fall over?
I've tried connecting them to several different models/makes of network switches and nothing resolves the issue. Even just having them sitting on the network (be it either static or dynamic IP) with no associated print queue still results in the same issue so I can only assume that it's some kind of broadcast packet? The issue doesn't seem to affect any other network printers or devices as far as I can see. The only fix is to power the printer off and back on again (IT Crowd style!).
I've got a call logged with HP but so far they haven't been able to suggest anything. I've tried firmware updates, enabling the local firewall on the printer and disabling unused protocols on it but no joy so far. I'm absolutely at a loose end as to how to deal with the above problem?
Has anyone any suggestions of a way to try and track down what's causing these printers to randomly die every couple of days when on our LAN?
