Parallel/Printer ISA Card Jumpers Settin

Greetings:

I have a paralled card with no manufacturer nor FCC# printed. All you can read is “ECP-2A V1.2”. My question is, how can I set those jumpers settings according the the LPT that I want? No configuration tables printed on either front and back.

Three parts of jumpers on the card:
Group J7-J11 ~ sets of three pins
Group J15 ~ 6 sets of two pins
Group J16-J17 ~ 1 set of three pins

This is a very challenging qs, and I bet nobody knows it! Prove that I’m wrong!

Ps: Image of the card is available upon request.

Thanks,
Dean.
