You have Printer shared with another PC and it keep goes offline. Problem?

You may find, as I have done recently, that a network printer installed on a Windows 7 starts suddenly showing as Offline even when other machines on the network can access it fine

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.

Do the following Steps

  1. Reconnect the printer with shared PC (server)
  2. Restart your PC and check if still its says printer is offline?
  3. Go to Run<services.msc>-Find Printer spooler and restart the service
  4. 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
