to the Bleeping Computer Windows 10 Support Forum.
Sorry to hear that you are experiencing issues with your wireless printer. Some more information would be helpful: printer model, computer make and model, which version of Windows are you running, etc. I presume that you are running Windows 10. What is the build number? Specifically, could this issue have arisen after the Creator's Update (Build 1703)?
You can try rebooting your modem to reset it.
There are many other possibilities, such as your firewall may have decided to block access to your printer (try turning it off to see if you can print)?
You may have been "sideswiped" by a Windows update that is not compatible with your wireless printer driver. You should check the Dell website to ensure that you have the latest printer driver and firmware update for your model of printer.
The wireless access may have been accidentally turned off in the printer - check the settings and make sure that they are correct. We had an Internet tech here at our home a few weeks ago, who modified our wireless network in fixing another issue, rendering all of our wireless devices incapable of communicating without being configured to the slightly different "new" wireless network.
If I were you, I would also go to the Dell Forums and search your printer model for posts reporting similar issues. "Mr. Google" is your friend.
Please get back to us with more information and whether you were able to resolve the problem. If you are using Bitdefender as your anti-virus/firewall, as I am, then the firewall settings may have to be "tweaked."
Thank you and have a great day.
