None that I'm aware of.

That anything gets through implies that at least the software is setup
correctly, so the remaining factor is hardware.

That's a *really* long cable.  Also, *MAKE SURE* that neither machine
has another device using it's interrupt, and that there is a driver for
all hardware that generate interrupts.

If you happen to use the commonly-used IRQ 7 for the parallel port and
something other than the parallel port either generates interrupts on 7
or one another unregistered port you'll have lots of problems.

Make sure both machines have don't have IRQ conflicts and shorten the
cable.
