How to: Fix a network printer suddenly showing as offline in Windows Vista, 7 or 8

This post has become quite popular – so I’ve updated it with a bit more detail, plus some people’s experiences from the comments. If you find it useful then please leave a comment – or, even better, if I’ve saved you time and money then donate a bit to cover my hosting costs.

You may find, as I have done recently, that a network printer installed on a Windows Vista starts suddenly showing as Offline even when other machines on the network can access it fine. I originally thought it would be an IP address issue, but it turned out not to be anything to do with that. In fact, the solution was far simpler – but also slightly strange…

It turns out that Windows Vista automatically enables SNMP support for networked printers, and if it can’t get a response to a SNMP message then it assumes the printer is offline. SNMP stands for Simple Network Management Protocol and is a way of getting information from network devices (such as routers, servers and printers), mainly for the purposes of finding out if there are any problems with the devices. A number of networked printers implement SNMP, and will respond to SNMP queries with information, but some don’t. My printer (a fairly old Lexmark T640) is one of the ones that doesn’t implement it – so of course Vista will never get a response to a SNMP message. The result of which is that the printer will start showing as offline at a seemingly random time because Vista has just sent a SNMP message to it, and it hasn’t responded.

Thankfully there is a simple way to fix this – and it just involves telling Vista not to try and communicate with the printer via SNMP. Simply right-click on the printer in the Printers window, choose the Ports tab, and select Configure Port. At the bottom you will see a checkbox saying something like SNMP Status Enable. Untick that, and the printer should start showing as online again.

That should be it…but here are a few other tips/observations from people who’ve commented on this post:

  • This has been found to work on a variety of versions of Windows including
    • Windows Vista
    • Windows 7
    • Windows 8
    • Windows 8.1
    • Windows 10
    • Windows Server 2003
    • Windows Server 2008
    • Windows Server 2012
  • You could need to be logged in as an administrator before you can change the SNMP status
  • If you’re running Windows 8 then this could be the problem instead (thanks Gompo)
  • If you find that this solves it for a bit but it keeps going offline again then editing the registry at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print and adding a new DWORD called SNMPLegacy with the value 1 and restarting may solve it (thanks Coxy)
  • The issue can be caused even when the printer does support SNMP, but somehow the SNMP communications aren’t getting through – for example, due to a firewall or port configuration issue somewhere on the network (thanks Jonathan)
  • Setting the SNMP ‘group name’ to “public” can also help (thanks PP)

    This didn’t work for me. What I have found, however, was that the printer is set up for a dynamic IP address and this is different from the IP address in the port config. Win 7 won’t let me reset the port IP address, so I’m trying to switch to a fixed IP address (which I’ll set to what is in the port). This is a fiddly issue. Can anyone recommend a good piece of diagnostic software that looks after this sort of thing?

    Yay! This worked, took me about 2 seconds. Thank you!

    am using ricoh printer… that snmp public doent work… it shows offline..

  12. Patricia Daly says:

    When I click on the Configure Port box, I do not see “checkbox saying something like SNMP Status Enable.” The only thing that pops up is box indicating how many “Transmission Retry”. Can you help??

  13. Pavel Krolatov says:

    Worked for me

  14. Thank YOU!! ITS working as perfect as you explain

  15. Scarlett says:

    it worked….
    the box was checked, in-checked it and checked it again….and this adds number 4 fix…..but so far.. its printing

  16. arun says:

    thank you very much

  17. garit says:

    my printer comes up with the error
    “An Error Occurd While Printing”

    then it will not print, i can print from the CPU information like on board Paperwork, But it will not print E-Mails …

    I’m a 25 year network engineer. I just had this start happening on my home network with an HP LJ P3005dn that I have had running perfectly fine for years. My is a pretty beefy Dell Optiplex with Win7 x64 and the only workaround was to start/stop the Printer Spooler service every time I needed to print (simply because I was annoyed and didn’t have time to lookup a real fix). Found your post ant that was exactly the issue! A huge thank you for solving such an annoying problem.

  19. Andrew says:

    I had been restarting everything, checking cables and IP addresses, nothing worked.
    Found your post and a minute later back up and running. Many thanks.

  20. Kurt says:

    Thanks for all the comments. I’m on Win 10. My brother HL2135W was offline, the troubleshooter helped, I’m printing once again !

  21. José says:

    Also have Ricoh, how did you fix this?

  22. Simon says:

    I have a Ricoh C3500 and this worked following the Configure Port step disabled SNMP. I have pulling my hairs out for weeks. Thanks!

  23. Simon says:

    For those with Ricoh, make sure you try disabling both in your printer setting in Windows AND on Ricoh printer web utility.

  24. Amanda says:

    Hi, this seemed to work, it made printer say ready instead of offline, but after testing it, it now says “error” instead of ready, and not printing… any idea what I should do next? thanks!

  25. Alex Romp says:

    I’ve been doing this a VERY long time but for some reason, despite this being a default setting on IP printer ports, I was yet to run into this problem.

    I think the fact that there seven pages of comments and counting speaks to the fact that you are largely alone in finding a simple yet effective solution to this issue.

    Thank you very much for writing it up and sharing it.

  26. Sharon says:

    When I clicked on Configure Port I got this message “An error occurred during Port Configuration. Access is denied.” What does this mean?

  27. Jordan says:

    Thank you very much for this fix! I spent hours yesterday trying to get a certain laptop to print properly, but it would only print while powering on.

    This guide fixed the issue in no time!

    thank you very much for this information. now my printer is working perfectly.

  29. edan says:

    work like a chram!

  30. Jim says:

    Thanks! This was driving me crazy on a Window 7 laptop.

  31. Margaret says:

    I have a Brother multi function centre, connected wirelessly, and it is showing offline. This fix is not working for me as I am not able to Configure the port, getting the message “An error occurred during port configuration. This operation is not supported.” So the window doesn’t open for me to turn the SNMP off. Open to suggestions.

  32. Bogdan says:

    Worked for me !
    Printer : Dell 1720 DN with Vista x64 drivers (same as for Win 7) running on Windows 10 PRO x64

    I love you. Thanks.
