When attempting to print from FileMaker Pro v12 or v13 to any printer we get the following error: "Printing cannot continue because this printer is not connected to a port. Use the Control Panel to set up a port. This is only a problem with FileMaker. All other applications print fine. It is also limited to a couple of computers. Most computers on the same network, also using FileMaker can print just fine. I've scoured the web and mostly have found solutions that point to adjusting the compatibility settings in the FileMakerPro.exe, but that doesn't seem to help either. The affected machines are running Windows 7 Professional.
