I'm sitting here waiting to be proved wrong, but that sounds like a
load of Cargo Cult to me.

I'd be wary of making changes to your system based on what you read
about "error 255". Read the second paragraph of this instead:

https://msdn.microsoft.com/en-us/library/windows/desktop/ms681382

The error codes listed here will result from windows system calls
buried deep in some code. But who says it was a system call that
provoked the error, rather than some error detected in, say, LP,
python or one of the other programs involved?

The only simple numerical interpretation of the OP's return¹ code
is that it's 4 expressed in 30 inverted bits. (I'm assuming no one
has devised a list of 1073741823 error numbers.) This is just as
likely to be incorrectly interpreted without knowing exactly where
and by whom it was issued.

¹here, error number ≡ return code.

Cheers,
David.
