    I disabled snmp under port settings on each of the printers that have gone offline. They then came online. Yay!!

    Thanks

    If it's a managed switch check to see if there is an active MAC address on the port the printer is plugged in to. The HPs send virtually no traffic out so drop off the network. You can alter the SLP settings to make them chattier to help stay active.
    What switches are you using? also was this p2055?
    Thats a possible but we just got a report from a user where they have not had the issue in 3 weeks and we have not changed anything to do with SLP. We are not sure which setting seems to have fixed it yet (for a p2055) but I am using another printer with defaults restored and gradually changing the setttings.

    Did they work though? It should always show offline I think because without SNMP it doesnt check any other way?
    When you have an offline one did ping work?

    Procurves, the SLP setting can only be changed via telnet, not the web interface on the printer.

    Disabling SNMP will stop windows detecting the port type correctly when you add it.

    Edit: Printers affected are:

    3005
    2420
    4200
    4250
    5550

    OKI and Xerox are also affected.

    The HP 2015's have a major problem with Formatter boards.
    If you are lucky and yours are still under warranty you should check and update your firmware and get the formatter replaced if affected.

    This is a manufacturing issue to do with dry joints on the formatter pcb.

    The boards are all flow soldered so not much chance of a DIY repair. There are plenty of reports of people baking them in an oven in an attempt to bring them back to life!

    The 3600's are Host based and only work reliably if you install the driver locally on a local TCP/IP port, I have tried servicing the 3600's on a server queue and have since given up.
    I have 30 users printing to 3 of them, since installing the drivers locally they have been as good as gold.

    I have 6 x 2015's, 1 died after 3 months HP replaced the formatter. Now two more have died in the same way just out of warranty thats a 50% failure rate.

    Since HP switched production to China the reliability of these printers has just nose dived.

    Google for "HP 2015 Formatter" or visit the HP Forums to see how unhappy 2015 owners are!
    Shame because they had a great feature set for such a small footprint. If only they worked

    I should point out that it only became a *major* issue when we implemented 802.1x. Normally the traffic will be on the same vlan and will make it to the printer, if you are being routed via the switch then this would also cause issues when the address was deleted from the table.

    Just found this thread, really intermittent problems with printers going offline. I have a K5400 thats doing it, a P2015n that seems to have sorted itself out and a crappy Edimax print server thats just started doing the same.

    Weird how its happened around the same time for everyone.

    We have this problem; I know our switches are configured to not age out the MAC addresses for the printers.

    I've got this problem with an Oki C830. It goes offline after about 30 seconds on the server, but connecting it via tcp/ip on my workstation it works fine.
