Appreciate this may not be the most appropriate location for this request/problem but thought I would post regardless as I can't find anything more suitable!
We have several HP 2605DN printers that keep dropping off then re-attaching to the network. The printers drop for about 20 seconds then come back online.
I have tried the usual hardcoding the speed and duplex at both ends, looking into flow control, upgrading the firmware on the printers, etc but am still having no joy.
The issue has been logged with our print company and even escalated to HP who still are yet to find a solution.
I have forwarded them the config of the switch and the dump from 'sh tech-support' but still no joy.
I really want to fix this problem as the errors are filling my syslog server!
As a workaround on one of the printers I have installed a Netgear print server in between the switch and printer and this has resolved the problem. I really dont want to go down this route though for the other devices as it is another device to manage on the network and you are unable to monitor them.
Any ideas? Thanks chaps as always,
