Facing problem in NI VISA.

[Hasni]

Hello,

I am using VISA to communicate with the parallel port but when i run my program it gives the following error

"Error -1073807339 occurred at VISA Write in" and the given possible reason is "VISA:  (Hex 0xBFFF0015) Timeout expired before operation completed." Please help me what should i do to correctly communicate with the parallel port.

Regards,

Husnain Taseer

Did you ground the necessary pins? See this document for details: http://digital.ni.com/public.nsf/allkb/B937AC4D8664E37886257206000551CB
