Parallel Port Communication--- resource is valid, but visa cannot access it. Error code is -1073807246

[StevenInToronto]

Hello,

I am trying to control parallel port communication. But never success.

I ran the sample VI: parallelportconnection.vi I got a error on Probe1. The error information is shown below.

Error -1073807246 occurred at VISA Write in ParallelPortCommunication.vi

Possible reason(s):

VISA:  (Hex 0xBFFF0072) The resource is valid, but VISA cannot currently access it.

Please give me some help.

Did you open the parallel port in another application?
