Question about Office Equipment & Supplies
I get a "The computer is unable to establish two-way communication with the device" message when on the "Estimated Ink Levels" tab in the "HP Photosmart C3100 series Toolbox" dialog. I just wanted to see the levels, I think they may be low on magenta and yellow. Anyway, uninstalled "all" of the software and reinstalled. Still the same problem. Any help would be appreciated...

I came across this similar problem and spent days trying to figure it out. I knew I was close when I tried to start the HPZ12 service and it kept failing with "unable to find the specified file". I traced it with a process monitor and found that it was looking for a registry key that was not present. Specifically:
HKLM\System\CurrentCosntrolSet\Services\Pml Driver HPZ12\Parameters
It was looking for the string:
which should be set to:
(or something similar).
The unfortunate thing is that no matter how many times you install and uninstall the HP drivers, then don't reset the registry keys for the HPZ12 service. In the end, I ended up doing the following:
1. Uninstall software and reboot
2. Go through registry editor and delete the PML key (just did a search for all PML occurences)
3. Deleted the c:\program files\Hewlett-Packard directory
4. Deleted the c:\program files\HP directory
5. Deleted the c:\windows\system32\spool\drivers\w32x86\ contents (anything that referred to an HP printer or driver)
6. Deleted the HKLM\Software\Hewlett-Packard registry key
8. Reinstalled and everything worked.
I suggest you backup any registry keys prior to deleting them in case you make a mistake. You can use the Export feature on the right-click context menu to save each key you delete, or use some tool to make a backup of your registry prior to making these changes. Similarly, for the files, I renamed directories or created backups of their contents.
Once I reinstalled, I found that there were TONS of new registry keys added that weren't there before. So the real problem is with HPs install/uninstall. It doesn't clean up properly and any aborted or failed instalation will leave the drivers in a poor state.
Hope that helps.

I could not see the ink levels on my Photosmart 8450. Message said: "The computer is unable to establish two-way
communication with the device."
I opened up services.msc and scrolled to the Pml Driver HPZ12 entry. I found that it was disabled. I enabled/started it and my ink levels now display properly.

I have the same problem. No estimated ink levels show through the toolbox. But I can check my ink levels by typing in my printer's ip address in browser address bar which takes me to online toolbox page. There it shows my estimated ink levels fine along with other info.

Has anyone tried this and does it work? I have HP 6310 on a Lenovo T61 running Vista with USB connection. In addition to print levels, I am not able to FAX from PC.
