How to access parallel ports using LabVIEW?

[satish]

I want to send data to a device which is connected through LPT1.when Iam using serial port write.vi with port number 10(for LPT1) it is giving an error code 37 which means the device not found. whether those vis are only for accessing serial ports? Then how to access LPT1 using LabVIEW?

Most likely you need to modify your labview ini file to let it know that LPT1 (or whichever) will be controled through the serial port control. See the following link for a knowledgebase answer to this question:
