I have an HP OfficeJet 8500 A910 installed a couple months ago. On first install the HP software could communicate with it from two computers--one XP and one Win7. Now I can scan to the locations I setup before and print from both computers, but when I try to run the HP software that was installed and working on either computer, I get "...unable to establish two-way communication with the device". I have tried all the troubleshooting and downloaded the diagnostic tool. I have disabled both the Norton and Windows Firewalls.
Any suggestions would be appreciated.

How is it connected? If a network, tell me about your network - router brand/model, encryption type (WEP, WPA, etc) and ISP type (DSL, Cable, etc).
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.

I have the same problem. I am using a wireless network. The problem is only noticeable in HP Solution Center (HPSC). HPSC identifies the printer as being disconnected. Yet all the tools work except for when in Settings and trying to determine the estimated ink levels. Network setting are obtained correctly, scanning and faxing work.
Please let us know if you have been able to resolve this problem. Thanks.

I have the same exact problem. All of my computers are able to print to my HP 8500A-A910g Plus Printer using an ecrypted network connection. But if I need to check my ink status, I can only do by hitting the ink status button on my printer. I attempt to check my printer ink status I get the error message "The computer is unable to establish two-way communication with the device". All of my pc's and laptops are running Windows 7. We have a Linksys WRT3300N Wireless N Broadband Router.
I would be interested in a resolution to this problem. Thanks !!

I have a similar problem. Brand new HP Officejet Pro 8500A Plus, wire-connected to router.
I am unable to print/scan/fax on my Windows XP when Symantec Endpoint Protection is turned on. I have to disable it to be able to print/scan/fax.
I can do all capabilities with my Win7 computers. This seems to be a Win XP related problem.
I have checked for HP PML service...not listed. I show HP Port Resolver and HP Status Server and PML Driver HPZ12 started.
Doesn't bode well for keeping Viruses and other malware at bay. Any suggestions?

What should be done if the service isn't running? My computer says everything works fine but can't two-way communicate and my printer says it's setup properly... NOTHING will print though!
