HP 8740 error all the sudden

[howdylou]

All of the sudden I cannot print on my HP 8740.

All I get is an error message that says 

" DNS/Gateway Problem"

"The printer could not connect to the server. Contact your administrator or the person who set up the printer."

I have no idea what to do.  I have tried everything I can think of.

Thanks

@howdylou,

Thank you for posting your query on HP Community,

Let’s start by performing a network power drain. Follow the steps below:

Turn off all the devices connected on your network including the PC, Smartphones, printer, modem (if present) and router. Make sure all the devices in the network are turned off / unplugged.

Wait for 2-3 minutes.

Now turn on the modem if present. Wait till all the lights are steady and idle.

Then turn on the router. Again wait for a couple of minutes so that the lights are all steady.

Then turn on the PC and other devices.

Next thing, I would suggest here is to update the printer firmware. If your printer connected wirelessly, make sure to temporary connect the device with USB and then follow the link to install the latest firmware update on your printer from our HP support website. Click here to download and install the latest firmware. Once done, restart the computer.
