If this is a printer is on a TCP/IP port, turn off SNMP.

Start > Printers and Faxes > right click on your printer > Properties > Ports tab > highlight what port it's using > Select the Configure Port > Uncheck SNMP.

This may work for both Foodkop, and TVeblen

I became convinced it was the router. And believe me, I played with every setting on that thing!

Hey thanks Anak. I will test that out at the next opportunity (the issue affects other peoples laptops, not my desktop).
I'll post back what I find.

Your welcome! If it has a SNMP v1/v2 option in the Networking tab disable them also.

Hey Anak

No joy. There is no setting available. It was worth a try! Maybe that is available on a wired network?

But wireless you get the EpsonNet configuration:

Our printer is presently hard wired directly to the PC. When I went to check the setting an error showed that, that configuration was not supported. Presumably because it was a direct connection, and not on a network or the printer firmware does not support it.

Some other thoughts:

  1. When you right click on the printer name and if it has an offline status listing, uncheck it.
  2. Also check to assure the relationship between the printer, and the PC has not been set to 'sleep' or 'power save' mode or 'Allow the computer to turn off this device to save power'. If the printer “sleeps” it could appear “offline”.
  3. Different printers have different ways to reset to their default values. Have you tried resetting the printers to their 'defaults'?
  4. Have you made sure the printers you work on have up to date firmware / software? Tried re-installing the drivers?
  5. Try stopping the Print Spooler service, reboot, then restarting the service, reboot, any improvement?
  6. Checked to make sure the printer(s) are not on some type of automatic (timed) schedule? If so, change to 'always available'.
  7. Try configuring the LPR community name on the printer itself, and then do the same within the print queue setting. This link may offer assistance: Overview of Print Management
  8. Usually a network printer can be set to get its IP address from a DHCP server. But have you tried to TELNET into the ip address to set it? puTTy is a helpful tool.

Oh noooooooo. I wasted half my life (slight exaggeration) working on that stupid printer. After years of therapy I was finally able to let it go. And now your're trying to suck me back in!

With the exception of the TELNET fix I have tried many, many things, up to and including tying little pink ribbon bows on all the router's antennae just to get it to like me.

I have become convinced that my issue has something to do with the Beacon process. The router sends out a periodic beacon signal to discover which devices are still connected to the network so it can hold the address in the table. If the device does not respond within the proper protocol then the router frees up that address and "drops" the device. Either the router or the printer will not play nice with each other. (Note: this is my opinion, not an informed diagnosis). And yes, I have tried every beacon interval, even ridiculously long and short ones.

But let's wait and see what this will do for the OP. Your suggestions are all things he should try, and we haven't heard back from him/her yet. I'd hate to hijack the thread with my issues!

Thank you for my 'chuckle of the day', especially those first two paragraphs.

I understand, and agree.

Well, I finally gave up and purchased a new router. The straw that broke the camel's back was when it changed the IP Addresses of both laptops to the same thing. Only one lap top was able to connect to the Internet; the other one had to be reset by unplugging the router (severall tmes!) and waiting. Ugh! Enough is enough!

I was told that a router usually is good for about 2-3 years and when the IP Addresses start getting changed, it's a "sign". So, I guess my IP Address has been solved .... Thanks for all of your help!

Please let us (me) know if a new router solves it.

My router TrendNet TEW-691GR. I have not been motivated to try another because the router and printer are both new. The thing that complicates my installation is that I bought and installed the router and started using the wireless printer with the laptops right about the same time. So I can't determine whether it is the router or printer decisively.
