'No Computer Connection​' error message when saving memory card pics

Question

The printer is an HP Photosmart Premium C309g-m connected as a network device to an infrastructure communication mode wireless network.
There are no problems printing documents.
Documents have also been scanned and sent to specific computers on the network in the past.
So it certainly seems that there is a computer connection.
When a memory card holding pictures is inserted into the wireless printer and one tries to save the memory card pictures from the printer to a network computer without a memory card slot, one gets the error message, 'There is no computer connection'. 
The Wireless Network Test Report Diagnostic Summary is all PASS with Very Good signal strength.
The Diagnostic Utilities were useless to me. I can only guess at what the problem might be because it isn't specifically mentioned as a possibility.
I tried turning the firewall off but it made no difference.
The documentation mentions UDP Port 427 but doesn't state the protocol to be entered into the slot for Windows Firewall.
There is a list of exception files but no detailed information on how to add them as exceptions into Windows Firewall.

Answer 1

Try this basic troubleshooting fix:
1 - delete the IDVD preference file, com.apple.iDVD.plist, that resides in your
User/Home/Library/ Preferences folder.
2 - delete IDVD'S cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iDVD folder. 
3 - launch IDVD and try again.
NOTE: In Lion and Mountain Lion the Home/Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
