This soluton was povided to me by HP -- it has worked for me and several other folks. I do not recommend downgrading the firmware as several other posts have mentioned -- I think that is unnecessary. Good luck...
Below are the steps that you need to follow in the order as mentioned ...
Disconnect the printer from the NETWORK --If on wired network : Unplug the Ethernet cable from back of the printer. --If on wireless network : Power of the Wireless router. Turn off the printer.
Wait for 30 seconds. Turn on the printer.
If the printer is in READY state, on the printer front panel, go to Setup -> Network Setup -> Network Services -> IPv6 -> Off. Turn off the printer. Wait for 30 seconds and then turn on.
This was a spot on resolution. thanks again for the direction it worked the first time I tried it. The only addition to the instruction that I wasn't sure of was should i have reconnected to the network before printing or not but I just printed a report before reconnecting. Not sure that made much of a difference but your instructions were perfect. I will be sure to pass on this information if I come across someone with this particular issue.
