I came home from a trip and can't print anymore over wifi. Nothing changed on the wifi system. Here is what I have:
Lenovo laptop windows 7 Pro, service pack 1, 64 bit
Epson printer NX625
Brother printer MFC-685CW
Apple Airport Extreme
Apple Airport express as extender
I can scan from the Epson printer but not print over wifi. Ran a USB cable and can print over it.
I can't print to the Brother which worked before.
I can print from a desktop to the Brother over wifi.
I have tried uninstalling the printers, shutting down firewall, reconfigured the whole wifi network, nothing helps.
I can connect to the desktop over wifi and save files on it's hard drive.
Thanks for the thorough post. You've done some good troubleshooting.
When something like this has happened to me in the past, it's usually because a DNS setting has lingered in my laptop from one of the wifi networks I connected to.
On your laptop, open a command prompt. Start, Run, CMD.
At the prompt type ipconfig /flushdns
Then renew your lease on your IP.
See if that helps.
Can you print over wifi to the Epson from the desktop?
