Communicating with SPI interface via LPT port

[kgbullis]

Hi everyone,

I am a student intern working on a project that uses a MCP2515 CAN controller ... I have found that we are to connected the SPI interface to an LPT port (parallel port), as shown in the attachment. Now we are wondering how we are suppose to communicate to the SPI via LPT. It seems like I have looked everywhere and I am unable to find an answer, and I was hoping someone may have an answer or any information that could possibly help me.

Again all I'm trying to find is how do we communicate with the SPI interface via LPT.

I have made a program that enables one
to 'do' SPI communications via LPT1:
