LabVIEW only supports port I/O natively on the Windows OS due to the availability of port communication built into the Windows API. There is a knowledgebase on this issue, which I have linked here. If you have 3rd party software that does parallel port communication and provides DLL function calls, you could try using that with LabVIEW as a workaround.
