Filename: 203540.llb
Requirements: View

This example uses VISA to write data to the parallel port. NI-VISA 1.1 was the first version that supported parallel communications. If you have an earlier version, this example will not work. When using the parallel port, pins 2-9 are data pins with pin 9 being the most significant bit. Also, pins 11 (printer busy) and 12 (printer out of paper) must be grounded to transmit data.

How to access to higher address
This example is great for using VISA to access at the base address of // port output (0x378h). How it's possible to access to the other output port at the address (0x37Ah) of the // port with VISA structure.
