How do I pass data to and from an XS Board?

Q:

I want to send data from the FPGA to the PC through the parallel port (a 8 bit word). Can I do it using using the D0-D7 pins of the parallel port like bidirectional pins? Is the FPGA XS Board pins already connected to these lines?

A:

A better way to do that is using the status pins of the parallel port (s3,s4,s5,s6) and sending two nibbles (4bits) for one byte. Here are the documentation and project files for a similar design.
